Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The terms "first," "second," "third," "fourth" and the like in the description and in the claims of this application and in the above-described figures, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be capable of operation in sequences other than those illustrated or described herein, for example. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The technical scheme of the present application is described in detail below with specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
As users' demands for gaming experiences become higher, facial expressions are set for animated objects. Thus, the animation object is not a single stiff facial expression any more, and a vivid expression animation can be set for the animation object; the vivid expression animation can greatly improve the quality of the game and cater to the higher aesthetic feeling and experience of the game of the player. For example, a pinching face expression may be set for an animated object of a game.
Previously, the game animation production process was different from the movie animation production process; in the movie animation, an animation binding operator can bind the skeletal expressions of the roles for the animation objects, so that the effects of vivid body language and facial expression are achieved; in the game animation production process, the action is mainly reflected on the physical work of the animation object, and in consideration of cost time and performance, the action is not required to be added to the expression of the animation object at too much energy cost.
In the prior art, when facial expressions are set for animation objects of a game, an expression binding tool BonyFace can be adopted to complete the design of the facial expressions. However, in the prior art, an animation binding operator is required to design each skeleton for the face of the animation object, and then the skeletons are bound with the face of the animation object one by one, so that the animation object completes facial expression; therefore, more bones are required to be set for the animation objects, so that the fluency of the game can be influenced, and the performances of the game and the terminal can be further influenced; moreover, since animation binders are required to design bones and control relationships one by one, a lot of time is required to be consumed, and the design cost of each animation object is high.
The skeleton creation method, the skeleton creation device, the electronic equipment and the storage medium can enable the quantity of expression skeletons to be small, the fluency of a game cannot be affected, and the performance of the game and the terminal can be improved; the expression skeleton of the animation object can be quickly created, the time is less, and the design cost of the animation object can be reduced.
The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a bone creation method according to an embodiment of the present application, as shown in fig. 1, the method in this embodiment may include:
s101, creating a face initial point on each position point for the animation object according to the preset position point.
Optionally, step S101 specifically includes: receiving a creation instruction, and acquiring position points according to the creation instruction, wherein each position point forms the outline of the expression skeleton of the animation object; a face starting point is generated at each location point.
In this embodiment, the execution body of the embodiment of the present application may be a terminal, or a server, or a bone creation apparatus or device, or other apparatus or device that may execute the method provided in the present application.
Firstly, configuring a plurality of preset position points for an animation object; so that one face starting point can be created at each location point so that one location point matches one face starting point.
Specifically, a skeleton creation tool is provided, and an operation interface is provided, fig. 2 is a schematic diagram of an operation interface provided in an embodiment of the present application, and as shown in fig. 2, an operation field may be displayed on the operation interface, where options "create initial point", "create skeleton", "create controller", "create linkage", "select link skeleton" and so on are provided. The user may select "create initial point"; and then the creation instruction sent by the user can be received; the outline of the expression skeleton is preset, and a plurality of position points are arranged on the outline, so that the outline can be obtained according to the creation instruction, and a plurality of position points are obtained.
Then, at each position point, a face initial point is generated.
For example, fig. 3 is a model diagram of skeleton creation provided in an embodiment of the present application, and as shown in fig. 3, a plurality of face initial points are generated for a face.
For example, 4 face starting points are generated for each eyebrow of the animation object, 4 face starting points are generated for each eye of the animation object, 4 face starting points are generated for the nose of the animation object, and 10 face starting points are generated for each half face of the animation object.
If the number of bones to be generated is larger, the preset position points are larger, and the generated initial points of the face are larger.
S102, generating expression bones according to the initial points of the faces.
Optionally, step S102 specifically includes: the different initial points of the face have a connection relation; and connecting the initial points of the faces with the connection relationship to obtain each expression skeleton.
In this embodiment, since the face initial points have a connection relationship, the face initial points having the connection relationship can be connected, and each expression skeleton can be obtained.
For example, according to the operation interface of fig. 2, the user may select "create skeleton"; then, fig. 4 is a second model diagram created by the skeleton provided in the embodiment of the present application, and as shown in fig. 4, each expression skeleton is generated according to the connection relationship of the initial points of the faces of the animation objects.
For example, after obtaining the face initial point, the face initial point is configured with numbers, and the numbers have a connection relationship, for example, the face initial point 1 is connected with the face initial point 2, and the face initial point 2 is connected with the face initial point 3 and the face initial point 4 respectively; furthermore, the facial initial point 1 and the facial initial point 2 can be connected to obtain the expression skeleton 1; the facial initial point 2 can be connected with the facial initial point 3 to obtain the expression skeleton 2; the facial initial point 2 can be connected with the facial initial point 4 to obtain the expression skeleton 3.
S103, creating control nodes corresponding to each facial initial point on the expression skeleton according to the facial initial points to obtain an animation object provided with the facial skeleton, wherein the control nodes are used for driving the expression skeleton to move, and different control nodes have linkage relations.
In this embodiment, one face initial point corresponds to one control node, so that the control node corresponding to each face initial point can be created on the expression skeleton. In order to enable the expression bones to move, when the control nodes are established, the control nodes are preconfigured with linkage relations, and then the control nodes can drive the related expression bones to move; thus, the face skeleton is automatically configured for the model of the animation object.
For example, according to the operation interface of fig. 2, the user may select "create controller"; then, fig. 5 is a model diagram three of skeleton creation provided in the embodiment of the present application, and as shown in fig. 5, control nodes corresponding to each face initial point are created on the expressive skeleton.
After the expression skeleton is obtained, skeleton covering and rendering treatment can be carried out on the animation object according to each expression skeleton and each control node on the expression skeleton, so that the animation object after the skeleton covering can be obtained.
In the embodiment, a face initial point on each position point is created for an animation object according to a preset position point; generating expression bones according to the initial points of the faces; and creating control nodes corresponding to each facial initial point on the expression skeleton according to the facial initial points to obtain an animation object provided with the facial skeleton, wherein the control nodes are used for driving the expression skeleton to move, and different control nodes have linkage relations. Therefore, the facial initial points are automatically created for the animation objects according to the preset position points, and expression bones can be automatically generated due to the positions and the connection relations of the facial initial points; then creating a control node corresponding to each of the face starting points; the creation process of the expression skeleton is simple and easy to operate, and the skeleton can be quickly created for the animation object. The number of the expression skeletons of the animation objects created by the embodiment of the application is small, the fluency of the game is not affected, and the performance of the game and the terminal can be improved; in addition, by adopting the skeleton creation process of the embodiment of the application, the expression skeleton of the animation object can be quickly created, the control relationship between the skeleton creation and the manual matching skeleton is not needed to be manually created one by one, the time required for obtaining the animation object provided with the face skeleton is less, and the design cost of the animation object can be reduced; in addition, as different control nodes have linkage relations, the control nodes can drive related expression bones to move, so that the linkage effect of facial movement can be well restored, various expressions can be obtained, and the user experience of a user in the game process is improved; the model of the animation object is not changed when the facial skeleton is created for the animation object, and the obtained model of the animation object is suitable for being applied to games.
Fig. 6 is a flowchart of another bone creation method according to an embodiment of the present application, as shown in fig. 6, the method in this embodiment may include:
s201, creating a face initial point on each position point for the animation object according to the preset position points.
In this embodiment, the execution body of the embodiment of the present application may be a terminal, or a server, or a bone creation apparatus or device, or other apparatus or device that may execute the method provided in the present application.
This step can be referred to as step S101 in fig. 1, and will not be described in detail.
S202, a mirror image relationship exists between a face initial point on one half of the faces of the animation objects and a face initial point on the other half of the faces; and receiving a first moving instruction, moving the face initial point indicated by the first moving instruction according to the first moving instruction, and moving the face initial point on the other half of the faces with mirror image relation with the face initial point indicated by the first moving instruction according to the mirror image relation.
In this embodiment, an option of "moving an initial point" may be displayed; after the user selects this option, the user selects the face initial point that needs to be moved.
So that a first movement instruction indicating a face initial point to be moved can be received; and then moving the face initial point to be moved according to the first moving instruction to obtain the moved face initial point.
Since the left and right faces of the face have mirror image relationship when each position point is preset, the obtained face initial points have mirror image relationship, that is, the face initial point on one half of the face of the animation object has mirror image relationship with the face initial point on the other half of the face.
So that the corresponding mirror image relationship of the face initial points moves in real time as the face initial points on half of the face are moved. And further, the matching of the left face and the right face can be completed rapidly.
S203, generating expression bones according to the initial points of the faces.
In this embodiment, the step may refer to step S102 in fig. 1, which is not described in detail.
S204, receiving a second movement instruction, and moving the face initial point indicated by the second movement instruction according to the second movement instruction to obtain the face initial point after the movement adjustment.
In this embodiment, after the expression skeleton is created, the facial initial point may be further moved to match the model of the animation object, so as to adjust the position of the expression skeleton, so that the expression skeleton is matched with the model of the animation object.
The user selects a face initial point that needs to be moved. And further receives a second movement instruction sent by the user. Then, the face initial point indicated by the second movement instruction is moved according to the second movement instruction.
S205, receiving a trigger instruction, and moving the position of the expression skeleton passing through the initial point of the moved face according to the trigger instruction so as to match the expression skeleton with the initial point of the face.
In this embodiment, after the initial points of the face are connected, the expression skeleton is obtained; so that the expressive bone moves along with the facial initiation point after it is moved. Specifically, after moving the face initial point, the user can click on the option of "move skeleton"; then, a trigger instruction sent by the user is received, and then the position of the expression skeleton is automatically moved so that the positions of the expression skeleton and the initial point of the face are matched. Thereby realizing the position of the expression skeleton moving past the moving facial initial point according to the moving facial initial point.
S206, creating control nodes corresponding to each facial initial point on the expression skeleton according to the facial initial points, wherein the control nodes are used for driving the expression skeleton to move, and different control nodes have linkage relations.
Optionally, S206 specifically includes:
generating at least two control nodes corresponding to each face initial point at the position represented by each face initial point, wherein the at least two control nodes corresponding to each face initial point have a linkage relation, and the control nodes on the expression skeleton with the connection relation have a linkage relation; and generating a total control point for the animation object, wherein the total control point is used for driving all control nodes on the initial points of the face to move so as to drive the expression skeleton to move.
In this embodiment, in order to make the movement between bones meet the expression requirement, the linkage relationship between the control nodes may be preconfigured. Specifically, at least two control nodes are generated for each face starting point, the two control nodes of each face starting point having a linkage relationship therebetween.
For example, the face initial point 1 is set at the right end of the expression skeleton 1, and the face initial point 1 is set at the left end of the expression skeleton 2, so that the face initial point 1 is the joint point between the expression skeleton 1 and the expression skeleton 2; a control node a and a control node b are configured for the initial point 1 of the face, the control node a can drive the control node b to move, and the control node a and the control node b can drive the expression skeleton 1 and the expression skeleton 2 to move.
For another example, a face initial point 1 is provided at the right end of the expression skeleton 1, and the face initial point 1 is provided at the left end of the expression skeleton 2, so that the face initial point 1 is an articulation point between the expression skeleton 1 and the expression skeleton 2; control node a and control node b are configured for the initial point 1 of the face, the control node a can drive the control node b to move, the control node b can drive the control node a to move, and the control node a and the control node b can drive the expression skeleton 1 and the expression skeleton 2 to move.
Moreover, as the expression bones have a connection relationship, the control nodes on the expression bones with the connection relationship also have a linkage relationship. For example, since the interconnected expression bones have the nodes therebetween, movement of the control node on the node will drive the interconnected expression bones to move. For another example, the relationship between the connected expression bones is relatively close, so that when one of the expression bones moves, the rest of the connected expression bones also move; for example, the expression skeleton 1 is connected with the expression skeleton 2, the expression skeleton 2 is connected with the expression skeleton 3, the expression skeleton 3 is connected with the expression skeleton 4, and when the expression skeleton 3 moves, the expression skeleton 1, the expression skeleton 2 and the expression skeleton 4 all move in different amplitudes.
In addition, a total control point can be generated for the animation object, so that when the total control point moves, the total control point can drive all expression bones to move. For example, the user may select the option "select link skeleton" in fig. 2, fig. 7 is a model diagram three created by the skeleton provided in the embodiment of the present application, as shown in fig. 7, and then the user sets a total control point for the animation object, where the total control point is located at the lowest point on the chin of the animation object shown in fig. 7.
For example, 3 controllers, respectively, a first controller, a second controller, and a third controller, may be generated at one facial initial point of the eyebrow of the animation object; the first controller is used for driving the second controller and the third controller to move, the second controller is used for driving the third controller to move, the third controller drives the second controller to move by English, and each controller is used for driving the expression skeleton passing through the initial point of the face to move. All the expression bones on one eyebrow have a connection relation, so that a fourth controller is generated for all the expression bones on one eyebrow, and the fourth controller is used for driving all the second controllers on the expression bones with the connection relation to move. And generating a fifth controller for the animation object, wherein the fifth controller is used for driving all the first controllers to move so as to drive all the expression bones to move. Fig. 8 is a schematic diagram of an expression skeleton provided in an embodiment of the present application, as shown in fig. 8, the expression skeleton is provided for eyes, eyebrows, nose, chin, and the like, and a controller is provided on the expression skeleton.
Aiming at the requirements of different facial shapes and different precision, the positions and the numbers of the initial points of the configured faces are different, so that the positions and the numbers of the expression bones are different. For example, fig. 9 is a schematic diagram two of expression skeleton provided in the embodiment of the present application, as shown in fig. 9, when the accuracy requirement is low, the number of facial initial points is less, and the number of expression skeleton is less; fig. 10 is a schematic diagram three of expression skeleton provided in the embodiment of the present application, as shown in fig. 10, when the accuracy requirement is higher, the number of facial initial points is more, and the number of expression skeleton is more.
Since the facial initial point can be adjusted, the facial initial point can be deleted and added, and further the expression skeleton can be added and increased. Moreover, the linkage relation between the control nodes can be added and deleted, so that the linkage relation between the expression bones can be added and deleted; the linkage relation between certain control nodes is adjusted, so that the control nodes which do not have linkage relation with the control nodes are not affected. For example, the expression skeleton is divided into eyebrows, eyes, nose, mouth and the like, the above parts are mutually independent, and if the linkage relation between the controllers on the eyebrows is deleted, the linkage relation of other parts is not affected.
S207, creating an eye gaze controller of each eyeball of the animation object; and associating the eye gaze controller of each eyeball with the expression skeleton corresponding to each eyeball.
In this embodiment, a gaze controller may also be created for the eyes of each eyeball of the animation object, so that there is an association between the gaze controller and the eyeball.
