According to one embodiment of the present application, there is provided an embodiment of an animation generation method of a model, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer-executable instructions, and that although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different from that herein.

In a possible implementation manner, the embodiment of the present application provides a method for generating an animation of a model, and fig. 2 is a flowchart of a method for generating an animation of a model according to the embodiment of the present application, as shown in fig. 2, and the method includes the following steps:

step S201, a plurality of first models are obtained, wherein the plurality of first models are used for generating crushing animation of the second model.

In the technical solution provided in step S201, the second model may be a complete model, and the plurality of first models are crushing models of the second model, that is, the plurality of first models may be a plurality of sub-models corresponding to the second model, where the plurality of first models are used to generate the crushing animation of the second model.

For example, after the model is crushed, a complete model may be crushed into a plurality of sub-models, wherein the complete model may be regarded as a second model, the plurality of sub-models may be regarded as a plurality of first models, based on which the plurality of sub-models after the second model is crushed may be acquired first, and a crushing animation of the complete model may be generated based on the plurality of sub-models.

Step S202, merging the plurality of first models into a second model, wherein the vertex of at least one first model is used for determining the vertex of the second model.

In the technical solution provided in step S202, after obtaining the plurality of first models, because each first model is a sub-model of the second model, based on this, the plurality of first models may be combined to obtain the second model, where in the process of combining the plurality of first models, vertices of the combined second model may be determined according to vertex information of the first models, where the vertex information includes at least a vertex position, a vertex index, a vertex sequence, and an associated vertex of at least one vertex of the first model.

In this embodiment, after a complete second model is broken, the complete second model may be broken into a plurality of first models, in which case, a vertex in the second model may correspond to a vertex in two or more broken first sub-models, a position of the vertex in the second model may be determined based on vertex information of the vertex in each first model, based on which a position of each vertex in the second model may be determined based on a vertex position of the vertex in each first model in the plurality of first models, and then the plurality of first models may be combined based on the determined vertex position of the vertex in the second model in each first model, to obtain the second model.

Step S203, determining first weight information of vertices of the second model, where the first weight information is used to represent a degree of influence of each first target bone in at least one first target bone bound by the vertices of the second model on motion of the vertices driving the second model.

In the above step S203, each first model may bind at least one bone, where the center of the first model corresponds to the center of the bound bone, each first model corresponds to the bone to which it is bound, the vertex of each first model is bound to its corresponding bone, and the motion of the bone may drive the motion of the bound vertex, after the merging of the plurality of first models into the second model, since there may be overlapping vertices or edges of two or more first models in the plurality of first models, i.e. the vertex of the two or more first models corresponds to one vertex of the second model after merging, in which case one vertex of the second model may be affected by the two or more bones to which it is bound, based on which the first weight information of the vertex of the second model may be determined, the first weight information being used to represent the driving effect of the vertex of the second model on the motion of each first target in the at least one first target bone to which the vertex of the second model is bound.

In this embodiment, since bones are bound at the center of the first models, and the vertices in each first model are bound to bones that it is erected, in this case, when a plurality of first models are combined to obtain a second model, bones bound by vertices of the first model combined to vertices of the second model can be regarded as first target bones bound by the vertices in the second model, and each vertex in the second model is affected by all the first target bones bound thereto. Wherein if the vertex in the second model is merged from a vertex in a first model, in which case the vertex in the second model is affected only by a first target bone; if the vertices in the second model are merged from two or more vertices in the first model, in which case the vertices in the second model are affected by a plurality of first target bones, based on which the first weight information of the vertices of the second model can be determined according to the degree of influence of the first target bones bound by the respective vertices in the second model on driving the motion of the respective vertices, which degree of influence can be expressed by a weight value.

For example, assuming that a certain vertex in the second model is affected by two first target bones, for convenience of description, the vertex may be referred to herein as a vertex a, and the two first target bones may be referred to as a first target bone X and a first target bone Y, respectively, where the weight value of the vertex a affected by the first target bone X is 0.4, and the weight value of the vertex a affected by the first target bone Y is 0.6, based on this, the first weight information of the vertex a of the second model may be determined according to the weight values of all the first target bones affected by the vertex a, where the weight information of the vertex a includes the weight values of all the first target bones affected by which the vertex a is bound. Based on the method, first weight information for each vertex in the second model may be determined.

Step S204, determining second weight information of vertexes of at least one first model based on the first weight information, wherein the second weight information is used for representing the influence degree of each second target bone in at least one second target bone to which the corresponding vertexes of each first model are bound on the movement of the vertexes driving the first model.

In the step S204, as can be seen from the foregoing description, the first weight information of the vertex of the second model may include a plurality of weight values, where the plurality of weight values are the degrees of influence on the motion of the vertex driving the second model by all the first target bones to which the vertex of the second model is subjected, and since the second model is obtained by combining the plurality of first models, after determining the first weight information of the vertex of the second model, the second weight information of the vertex of at least one first model may be determined based on the first weight information, where the second weight information is used to represent the degrees of influence on the motion of the vertex driving the first model by each of the at least one second target bones to which the vertex of each corresponding first model is bound.

In this embodiment, as can be seen from the foregoing description, the first weight information of the vertices of the second model may include one or more weight values, where the weight values are used to represent the degree to which the vertices in the second model are affected by the first target bone to which they are bound. Based on this, the second weight information of the vertices of the at least one first model may be determined from the weight values in the first weight information of the vertices of the second model.

Continuing with the previous example, assume that the weight values included in the second weight information of the vertex a in the second model are 0.4 and 0.6, wherein 0.4 is used to represent the degree of influence on the driving of the movement of the first target bone X to which the vertex a in the second model is bound; 0.6 is used to represent the extent of the effect of the first target bone Y to which the vertex a in the second model is bound on driving the motion of the vertex. Since the vertex a of the second model is obtained by merging the vertices of the first model, it is assumed that the vertex a of the second model is obtained by merging the vertex a1 of the first model M and the vertex a2 of the first model N, wherein the first model M corresponds to the first target bone X and the second model N corresponds to the first target bone Y, based on this, the weight value 0.4 of the influence of the first target bone X on the vertex a of the second model can be used as the second weight information of the vertex a1 of the first model M corresponding to the vertex a, and the weight value 0.6 of the influence of the first target bone Y on the vertex a of the second model can be used as the second weight information of the vertex a2 of the first model N corresponding to the first target bone Y. Based on the method, second weight information for vertices of each first model may be determined.

Step S205, controlling the corresponding first models to move based on the second weight information to obtain skeleton animation of each first model, wherein the skeleton animation of the plurality of first models forms the broken animation of the second model.

In the step S205, since the first weight information is used to represent the influence degree of each second target bone in the at least one second target bone to which the vertex of each first model is bound, the movement of the vertex driving the first model may be driven by the movement of the bone, based on this, after the first weight information of the vertex of each first model is determined, the movement of each corresponding first model may be controlled based on the first weight information, so as to obtain the bone animation of each first model, where the bone animations of the plurality of first models form the crushing animation of the second model.

In this embodiment, since the second weight information includes the influence degree of each second target bone in at least one second target bone to which the vertex of each first model is bound, the motion of the vertex can be driven by the motion of the bone, so that the vertex in the first model can be controlled to move based on the second weight information, the motion of the vertex can drive the model to move, and further, the bone animation of the first model is generated, wherein the bone animations of the plurality of first models are played simultaneously to form the broken animation of the second model.

In at least some embodiments of the present application, a plurality of first models may be combined into a second model, so as to determine first weight information of each vertex of the second model, determine weight information of the vertex of the first model based on the weight information, and then control movement of the first model based on the weight information of the vertex of the first model to obtain a skeletal animation of the first model.

The above method of this embodiment is further exemplified below.

As an alternative embodiment, the animation generation method of the model further includes: binding at least one bone to each first model to obtain a plurality of bones of a plurality of first models; combining the plurality of bones into a skeleton of a second model; in the skeleton of the second model, at least one first target skeleton to which vertices of the second model are bound is determined.

In this embodiment, at least one bone may be bound to each first model, so as to obtain a plurality of bones of the first models, where the vertex of each first model is bound to the bone corresponding to the model, and movement of the bone may drive movement of the vertex of the model, and then the bones may be combined into a skeleton of the second model, where at least the first target bone to which the vertex of the second model is bound may be determined.

For example, since the vertex of each first model is bound to the bone corresponding to the model, and each first model is a broken model of the second model, based on this, the vertices of the plurality of first models can be combined according to the position of the vertex of each first model in the corresponding vertex of the second model, and since the vertex is bound to the bone, based on this, in the process of vertex combination, bone combination can be achieved, and the combined bone can form the bone of the second model. Since the vertices in the first model may be changed to one vertex in the second model after the two vertices in the two first models are merged at the time of merging, and since the two vertices in the two first models are bound to at least one bone, respectively, in this case, the bone to which the vertices in the first model before merging are bound may be regarded as the first target bone to which the vertices in the second model after merging are bound. Wherein if the vertex in the second model corresponds to a vertex in a first model, the first target bone bound by the vertex in the second model is one; if the vertices in the second model correspond to at least two vertices in at least two first models, in which case the first target bone to which the vertices in the second model are bound is two or more.

As an alternative embodiment, merging the plurality of bones into the skeleton of the second model comprises: and establishing a level relation among a plurality of bones based on the vertexes of each first model to obtain a skeleton of the second model.

In this embodiment, since the first model is a broken model of the second model, the bones bound by the first model are independent and are not affected by each other, but after merging the bones to obtain the skeleton of the second model, the movements between the bones are mutually affected, i.e. the movement of one bone affects the movement of the other bone, in which case a level relationship between the bones needs to be established, which may be a father-son relationship between the bones, and the father bone and the son bone may be determined based on the level relationship between the bones, wherein the movement of the father bone may drive the movement of the son bone, and the movement of the son bone may not affect the movement of the father bone. A hierarchical relationship between the multi-calcaneus bones may be established based on the vertices of each first model to obtain a skeleton of the second model.

Alternatively, since the vertices of the first models may bind a plurality of bones, a level relationship between bones may be determined according to a degree of influence of the bones bound by each first model on driving the motion of the vertices, wherein a level of bones may be determined according to a magnitude of influence of the bones bound by the vertices on driving the motion of the vertices, for example, a level of bones having a large influence is higher than a level of bones having a small influence.

For example, as can be seen from the foregoing description, the degree of influence of the bone bound by the vertex on driving the vertex can be represented by a weight value, and the greater the weight value, the greater the degree of influence of the bone bound by the vertex on driving the vertex; the smaller the weight value, the smaller the influence degree of the bones bound by the vertexes on the motion driving of the vertexes, and based on the influence degree, the level relation among the bones can be determined based on the weight value of the vertexes. For example, two bones bound by a vertex in the first model correspond, the first bone bound by the vertex has a weight value of 0.3 for the degree of influence of driving the vertex, and the second bone bound by the vertex has a weight value of 0.7 for the degree of influence of driving the vertex, and since 0.7 is greater than 0.3, in this case, it can be determined that the level of the second bone is greater than that of the first bone, that is, the second bone can be regarded as a parent bone and the first bone can be regarded as a child bone.

As an alternative embodiment, the animation generation method of the model further includes: at least one second target bone to which the vertex of each first model is bound is determined in the plurality of bones.

In this embodiment, at least one bone is bound to each of the plurality of first models, based on which the plurality of first models are bound to a plurality of bones, and the bones are combined to obtain a skeleton of the second model, where the skeleton bound to the vertex of the second model is a first target skeleton, and since the second model is combined to the plurality of first models, one vertex in the second model may correspond to one vertex in one first model, or may be combined to two or more vertices in the first model, that is, one vertex in the second model may correspond to two or more vertices in the first model, based on which the vertex in the second model may be bound to one first target skeleton, or may be bound to a plurality of first target bones. Thus, a second target bone to which vertices in the first model corresponding to vertices in the second model are bound may be determined based on the first target bone to which vertices in the second model are bound.

For example, assume that the target skeleton bound by the vertex a in the second model includes a first target skeleton X and a first target skeleton Y, where the first target skeleton X corresponds to the first model M and the second target skeleton Y corresponds to the second model N, where the vertex a is obtained by merging the vertex a1 in the first model M and the vertex a2 in the second model N, based on which the first target skeleton X may be determined as a second target skeleton bound by the vertex a1 in the first model M and the first target skeleton Y may be determined as a second target skeleton bound by the vertex a2 in the first model N.

As an optional implementation manner, step S203, determining the first weight information of the vertex of the second model includes: and determining first weight information matched with the crushing animation of the second model, wherein the first weight information is used for controlling each first target bone to drive the vertex of the second model to move so as to enable at least one first model corresponding to the vertex of the second model to generate the bone animation.

In this embodiment, since the second model is obtained by combining a plurality of first models, the plurality of first models are crushing sub-models of the second model, based on which first weight information matched with the crushing animation of the second model can be determined, where the first weight information is used to control each first target bone to drive the vertex of the second model to move, so that at least one first model corresponding to the vertex of the second model generates the bone animation.

For example, when a plurality of first models are combined to obtain a second model, the bone bound by the vertex of the first model combined to the vertex of the second model may be regarded as the first target bone bound by the vertex in the second model, and each vertex in the second model is affected by all the first target bones bound thereto. Wherein if the vertex in the second model is merged from a vertex in a first model, in which case the vertex in the second model is affected only by a first target bone; if a vertex in the second model is merged from two or more vertices in the first model, the vertex in the second model may be affected by a plurality of first target bones in this case. All first target bone effects on vertices in the second model may be represented by first weight information that may be used to control movement of vertices of each first target bone driving the second model.

For example, it is assumed that a certain vertex in the second model is affected by two first target bones, where the weight value of the vertex affected by the first target bone is 0.4, and the weight value of the vertex affected by the second first target bone is 0.6, based on this, it is possible to control each first target bone to drive the vertex of the second model to move according to the weight values of all the first target bones affected by the vertex a, so that at least one first model corresponding to the vertex of the second model generates a bone animation.

As an optional implementation manner, step S204, based on the first weight information, determines second weight information of the vertex of at least one first model, including: and adjusting the first weight information based on the vertex of at least one first model corresponding to the vertex of the second model to obtain second weight information of the vertex of at least one first model.

In this embodiment, after determining the first weight information of the vertex in the second model, the second weight information of the vertex of the at least one first model may be obtained based on the vertex of the at least one first model corresponding to the vertex of the second model, and the first weight information may be adjusted.

For example, the first weight information of the vertex of the second model may include one or more weight values, where the weight values are used to represent the degree of influence of the vertex in the second model by the first target bone bound thereto, and the vertex in the second model may be obtained by merging one or more vertices in the first model, where a mapping relationship exists between the vertex in the first model and the first target bone in the second model, based on which the vertex of the at least one first model corresponding to the vertex of the second model may be determined first, and then, based on the mapping relationship between the vertex in the first model and the first target bone in the second model, the first target bone corresponding to the vertex in the first model is determined, and the weight value of the influence of the first target bone bound by the vertex of the second model in the first weight information on driving the movement of the vertex is used as the second weight information of the vertex in the first model.

As an optional implementation manner, step S202, merging the plurality of first models into the second model includes: baking the first models respectively; and merging the baked first models to obtain a second model.

In this embodiment, in the process of merging the plurality of first models, baking operations may be performed on the plurality of first models, and merging the plurality of baked first models to obtain the second model.

For example, baking the plurality of first models is to render a map of the models based on the model application scene, and the baked models have more detailed information, so that the plurality of baked first models are combined in the later stage, the obtained second models are more complete, and in the process of combining the models in the later stage, the models do not need to be adjusted again, so that the computing resources are greatly saved.

As an alternative embodiment, the animation generation method of the model further includes: obtaining an original animation, wherein the original animation is used for displaying a process of shredding the virtual object represented by the second model; and determining a plurality of fragment virtual objects in the original animation as a plurality of first models, wherein the plurality of fragment virtual objects are used for forming virtual objects, and each first model is provided with a key animation frame of each corresponding fragment virtual object.

In this embodiment, the original animation of the second model is used to demonstrate a process of breaking up the virtual object represented by the second model, where the original animation includes a plurality of fragmented virtual objects, and the plurality of fragmented virtual objects may be determined as a plurality of first models, that is, the plurality of first models are broken models of the second model, where each fragmented virtual object is used to construct a virtual object, and each first model is fabricated with a key animation frame of each corresponding fragmented virtual object.

For example, when a virtual object is broken up, a plurality of fragmented virtual objects may be generated that combine to obtain the virtual object, wherein the virtual object may be represented by a second model and the fragmented virtual object may be represented by a first model.

As an alternative embodiment, the animation generation method of the model further includes: generating vertices of the second model based on at least one of the following information of vertices of the at least one first model: vertex position, vertex index, vertex order, and associated vertices of at least one vertex of the first model.

In this embodiment, since the second model is obtained by combining a plurality of first models, the vertex of each of the plurality of first models includes vertex information, wherein the vertex information of the vertex includes at least: the method comprises the steps of vertex positions, vertex indexes, vertex sequences and associated vertexes of at least one vertex of a first model, wherein the vertex positions are used for representing positions of the vertexes in a second model, the vertex indexes are used for searching the vertexes in the second model, the vertex sequences are used for representing vertex serial numbers of the vertexes in the second model, and the associated vertexes of the at least one first model are used for combining in the first model to obtain vertexes of the same vertex in the second model. Based on this, vertices of the second model may be generated based on vertex information of vertices of the at least one first model.

In one possible implementation, another method for generating an animation of a model is provided in the embodiments of the present application. FIG. 3 is a flow chart of a method of animation generation of a model according to one embodiment of the present application, as shown in FIG. 3, the method may include the steps of:

step S301, displaying a plurality of first models on a graphical user interface, wherein the plurality of first models are used for generating crushing animation of the second model.

In the above step S301, the plurality of first models are crush sub-models of the second model, and after the second model is acquired, the plurality of first models for generating crush animations of the second model may be displayed on the graphical user interface.

For example, the step S301 may be performed by animation software, where the animation software may be 3d Max software, and the 3d Max software includes a graphical user interface, and the 3d Max software may display the plurality of first models on the graphical user interface in response to acquiring the plurality of first models.

Step S302, in response to the animation operation on the graphical user interface, invoking the target plug-in to generate a skeleton animation of each first model.

In step S302 described above, when in response to an animation operation of the graphical user interface, the target plug-in may be invoked to generate a skeletal animation for each first model. The second model is obtained by combining a plurality of first models, the vertex of at least one first model is used for determining the vertex of the second model, first weight information of the vertex of the second model is used for generating second weight information of the vertex of at least one first model, the first weight information is used for representing the influence degree of each first target bone in at least one first target bone bound by the vertex of the second model on the movement of the vertex driving the second model, the second weight information is used for representing the influence degree of each second target bone in at least one second target bone bound by the vertex of each corresponding first model on the movement of the vertex driving the first model, and the bone animation of each first model is obtained by controlling the movement of each corresponding first model based on the second weight information.

For example, the 3d Max software includes a target plug-in, and the graphical user interface of the 3d Max software may include an animation control, when the 3d Max software responds to a selection operation of the animation control by a user, that is, responds to an animation operation acting on the graphical user interface, based on this, the 3d Max software may call the target plug-in to build a skeleton for each first model and record a mapping relationship between each first model and its corresponding skeleton, and then the target plug-in may combine the plurality of first models to obtain a second model, so as to determine first weight information of vertices of the second model, where the first weight information is used to represent an influence degree of each first target skeleton, which is bound to vertices of the second model, on motion of vertices driving the second model. After determining the first weight information of the vertex of the second model, the second weight information of the vertex of at least one first model may be determined based on the first weight information, where the second weight information is used to represent at least one second target bone to which the vertex of each first model is bound, and the degree of influence on the motion of the vertex driving the first model, and further, the motion of each corresponding first model may be controlled based on the second weight information, so as to obtain a bone animation of each first model. The method for determining the first weight information of the vertex of the second model and the second weight information of the vertex of the first model may refer to the methods described in the foregoing step S203 and step S204, and will not be described herein.

Step S303, displaying a broken animation of a second model formed by skeletal animations of a plurality of first models on a graphical user interface.

In the above step S303, in generating the skeletal animation of each first model, the crushed animations of the second model composed of the skeletal animations of the plurality of first models may be presented on the graphical user interface.

For example, after generating the skeletal animation of each first model, the 3d Max software may simultaneously display the skeletal animations of multiple first models on the graphical user interface to form a crushed animation of the second model.

In at least some embodiments of the present application, a plurality of first models may be displayed on a graphical user interface, wherein the plurality of first models are used to generate a crush animation of a second model; when the animation production operation acting on the graphical user interface is responded, the target plug-in can be called to generate the skeleton animation of each first model, and then the broken animation of the second model formed by the skeleton animations of the plurality of first models is displayed on the graphical user interface, namely, in the embodiment of the application, the skeleton animations of the plurality of first models can be generated through the target plug-in, and can form the broken animation of the second model, multiple skeleton binding is not needed, so that the computing resources are saved greatly, the computing efficiency is improved, the technical effect of improving the animation production efficiency of the models is achieved, and the technical problem of low animation production efficiency of the models is solved.

The technical solution of the embodiment of the present invention is further described by way of example in conjunction with the preferred embodiments.

In the related art, when generating a crush animation of a model, offline cutting is generally performed on the model of the crush animation to be generated based on a physical engine, then, a plurality of sub-models obtained by cutting are combined into a whole to obtain a complete model, the complete model comprises a plurality of sub-models, bones are erected in the plurality of sub-models, and then, the bones are bound, and finally, the bone animation is manufactured. However, after the multiple sub-models are combined, the center points of the sub-models included in the combined complete model are difficult to determine, which in turn results in difficulty in determining the center point of each sub-model when setting up bones in the sub-models, resulting in inaccurate bone setting up positions. In addition, in the process of merging a plurality of sub-models, there is a case where edges and vertices of the sub-models are merged and then overlapped, and based on this, when binding the vertices of the sub-models with bones erected by the sub-models, there is a problem that selection is difficult, and thus there is a technical problem that animation generation efficiency of the models is low.

In the related art, when a broken animation of a model is generated, after offline cutting is performed on the model to be generated to obtain a plurality of sub-models, bone binding is performed on the plurality of sub-models separately, animation is manufactured for each sub-model, and then sub-model merging is performed to obtain a complete model, so that the animation effect of each sub-model, such as the complete model, is achieved when the model is broken, but because one model only corresponds to one set of bone, in the process of merging the plurality of sub-models into one complete model, the bones of different sub-models possibly collide with each other, only one set of bone is reserved, and other bones are discarded, so that in the process of merging the plurality of sub-models into the complete model, multiple binding is needed, the combined complete model displays the bone animation of each sub-model in the process of model breaking, however, the multiple binding can greatly increase the calculation amount, and the technical problem of low manufacturing efficiency of the broken animation of the model is also existed.

However, the embodiment of the application provides an animation generation method of a model, by acquiring a plurality of first models, where the plurality of first models are sub-models corresponding to a second model, and the plurality of first models are used for generating a crushing animation of the second model, after the plurality of first models are acquired, the plurality of first models can be combined based on position information of the plurality of first models to obtain the second model, after the second model is obtained, first weight information of vertices of the second model can be determined, and the first weight information is used for representing an influence degree of motion of vertices of the second model on each first target bone in at least one first target bone to which the vertices of the second model are bound; and then, determining second weight information of the vertexes of at least one first model based on the first weight information, wherein the second weight information is used for representing the influence degree of each second target skeleton in at least one second target skeleton bound to the vertexes of each corresponding first model on the operation of driving the vertexes of the first model, and then controlling the corresponding first models to move based on the second weight information to obtain the skeleton animation of each first model, wherein the skeleton animation of a plurality of first models forms the breaking animation of the second model. In the process, a plurality of first models are combined into a second model, then, the weight information of the vertexes of the second model is determined, the weight information of each first model is generated based on the weight information of the second model, the first sub-model is controlled to move based on the first weight information, multiple times of skeleton binding is not needed, calculation resources are saved greatly, calculation efficiency is improved, the technical effect of improving the animation production efficiency of the models is achieved, and the technical problem of low animation production efficiency of the models is solved.

The method for animating a model according to an embodiment of the present application is further described below. FIG. 4 is a flowchart of a method for animating a model according to an embodiment of the present application, as shown in FIG. 4, the method comprising the steps of:

step S401, creating a corresponding skeleton for the crushing model.

In the step S401, the 3d Max three-dimensional software includes a self-made plug-in, and when the 3d Max software obtains the broken model of the complete model, the self-made plug-in can be called to bind the skeleton for each broken model, and the mapping relationship between the broken model and the skeleton is recorded.

In the embodiment, the self-made plug-in can be utilized for binding the bones of the crushing model, manual binding is not needed, the technical problems of inaccurate bone binding position and difficult vertex selection are solved, and the bone binding efficiency is improved.

Fig. 5 is a schematic illustration of a stalagmite model according to an embodiment of the present application, as shown in fig. 5, which is a complete model that can be crushed into multiple crushing models.

Fig. 6 is a schematic view of a stalagmite crushing model according to an embodiment of the present application, as shown in fig. 6, which can be crushed into a plurality of crushing models, each of which is a separate sub-model, the crushing models having irregular shape distribution.

And step S402, carrying out grid collapse on the broken model to obtain a complete model.

In the step S402, a self-made plug-in 3d Max software may be used to collapse the grids of the multiple crush models, so as to obtain a complete model.

Optionally, since each crush model is bound with a bone, and the vertex of each crush model is bound with the bone corresponding to the crush model, after the crush models are combined into the complete model, the bones of the plurality of crush models can be bound to obtain the bone corresponding to the complete model.

For example, since the vertex of each crushing model is bound to the bone corresponding to the crushing model, the motion of the bone may drive the motion of the vertex, and after the crushing models are combined into the complete model, since the vertices of some crushing models may overlap after being combined, based on this, one vertex in the combined complete model may be bound to multiple bones, based on this, weight information of each vertex in the complete model may be determined, where the weight information is used to indicate the degree of influence of the bone bound by the vertex on the motion of the driving vertex.

Step S403, skinning is carried out on the complete model, and the skinning weight of the vertex is restored.

In the step S403, after the complete model is obtained and the weight information of the vertex of the complete model is determined, the complete model may be covered, that is, the complete model and the skeleton corresponding to the complete model are bound.

For example, because the mapping relationship exists between the vertex of the crush model and the vertex of the complete model obtained after collapse, based on this, the weight information of the vertex of the crush model before collapse can be determined according to the weight information of the vertex after collapse, and then the determined weight information of the vertex is determined as the skin weight of the vertex.
