Detailed Description

The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

In order to solve the technical problems that the game running speed is slowed down and the game experience of a user is easily affected due to increased computing pressure of a server when the ambient light shielding processing is performed at present, the application provides an ambient light shielding processing method, as shown in fig. 1, the method comprises the following steps:

101. and acquiring a target model unit of the target virtual object, wherein the target model unit is a model unit to be subjected to ambient light shielding treatment and is provided with a minimum bounding box.

The target virtual object refers to a three-dimensional fixed object or a three-dimensional movable object in a virtual game scene, and the three-dimensional fixed object can be a virtual landform (such as a mountain and gravels), a fixed virtual article (such as a building, furniture and a statue) and the like; the three-dimensional movable object can be a virtual character, a virtual animal, a virtual vehicle (such as an automobile and a trolley), a movable virtual article (such as a sweeping robot and a fan) and the like; the target model unit is any model part of the target virtual object corresponding to the complete model, which needs to be rendered to generate the ambient light shielding effect, and can be understood as various head, back or leg parts of the virtual character.

In a specific application scenario, the target model units of each target virtual object to be subjected to the ambient light shielding processing may be preset according to the virtual object display requirements in the virtual game scene, for example, only one target model unit (e.g., a back) required to generate the ambient light shielding effect may be set in the virtual character, or a plurality of target model units (e.g., a back and a leg) required to generate the ambient light shielding effect may be set in the virtual character. For this embodiment, the target model unit of the target virtual object can be directly obtained according to the setting result, and the rendering of the ambient light shielding effect corresponding to the target model unit included in the target virtual object is further realized by performing the subsequent embodiment steps 102 to 104. When a plurality of target model units are simultaneously set for the same target virtual object, the rendering priorities of the plurality of target model units can be set according to the position composition of the model, and the rendering of the ambient light shielding effect of the target model units is sequentially executed according to the sequence of the rendering priorities from large to small, wherein the rendering priorities can be set according to user definition, and no specific limitation is performed.

The execution main body of the application can be a game client or a server, and can acquire the target three-dimensional texture corresponding to the target model unit after acquiring the target model unit of the target virtual object to be subjected to the ambient light shielding treatment; and then obtaining a target cube model of the target model unit, rendering the target three-dimensional texture by using the target cube model, and rendering the ambient light shielding effect of the target model unit according to the target cube model and the target three-dimensional texture.

102. And acquiring a target three-dimensional texture corresponding to the target model unit, wherein the target three-dimensional texture is a prebaked three-dimensional texture of the target model unit, and the size of the target three-dimensional texture is related to the size of the minimum bounding box of the target model unit.

The three-dimensional texture of the target is in a three-dimensional form and is characterized in that the texture information of a target model unit is recorded and is different from two-dimensional textures in a picture form, the recording form of the texture information corresponding to the three-dimensional texture of the target is a cube model, the texture information of the three-dimensional texture of the target comprises two parts, one part is a model unit texture with the same size as the target model unit, the other part is an edge extension texture of the target model unit, and the edge extension texture has a fuzzy extension effect in an extension area of the target model unit.

In a specific application scenario, after at least one target model unit of a target virtual object, which needs to generate an ambient light shielding effect, is determined, before the step of this embodiment is executed, at least one target model unit needs to be pre-baked to generate a static target three-dimensional texture, and specifically, a static target three-dimensional texture with a fuzzy extension effect is generated by setting a minimum bounding box corresponding to the target model unit and baking the minimum bounding box according to a bone joint of the target model unit.

Correspondingly, as an optional mode, after the target three-dimensional texture is generated, in order to realize resource reuse of the generated three-dimensional texture, a mapping relation between the pre-baked target three-dimensional texture and the target model unit may be created, and the target three-dimensional texture and the mapping relation are stored in the target texture atlas library. Correspondingly, for the embodiment, the target three-dimensional texture of the target virtual object corresponding to the at least one target model unit can be retrieved from the texture atlas library according to the mapping relationship, and then the target three-dimensional texture is bound to the main skeleton position of the target model unit, so that the movement of the target three-dimensional texture is consistent with the movement of the target model unit. By the method of splitting the target virtual object according to the model unit, respectively performing texture prebaking, and binding the three-dimensional texture generated by prebaking to the target model unit, the subsequent three-dimensional texture rendering and ambient light shielding processing can be accelerated. Rendering from scratch may take a significant amount of time, and therefore, some portions of the rendering are "baked" ahead of time for the selected target virtual object through the pre-baking process. Then, when the rendering is clicked on, the rendering of the entire scene will be faster, since the colors of these target virtual objects do not need to be recalculated. In addition, by generating the edge extension texture with the fuzzy extension effect and binding the edge extension texture to the target model unit, the target three-dimensional texture can generate a real ambient light shielding effect in a virtual environment when the target virtual object is at a fixed position or in a moving process, so that any virtual object close to the target virtual object can be influenced by the target three-dimensional texture. By means of splitting rendering according to the model units, custom rendering of the ambient light shielding effect of any model part of the virtual object can be achieved, and personalized requirements of game development are met.

103. And acquiring a target cube model of the target model unit, wherein the target cube model is used for rendering a target three-dimensional texture, and the size of the target cube model is the same as that of the target three-dimensional texture.

For the embodiment, since the recording form of the texture information corresponding to the target three-dimensional texture generated by the present application is a Cube model, in the using stage of the target three-dimensional texture, the target three-dimensional texture may be rendered by a target Cube model (e.g., Cube) having the same size as the target three-dimensional texture, and specifically, the target three-dimensional texture may be rendered to the back of the target Cube model (e.g., Cube), where the back of the target Cube model refers to a side of the Cube model facing away from the viewport camera.

104. And rendering the ambient light shielding effect of the target model unit according to the target cube model and the target three-dimensional texture.

For this embodiment, in the process of rendering the target three-dimensional texture, in the rendering stage, the target cube model may perform rendering determination on pixels according to the depth map of the view direction, and determine whether there is a crossing between the pixels of other virtual objects and the pixels inside the box corresponding to the target cube model. If the pixel points with crossed positions exist, world coordinates PW points of the interior sight of the target cube model and the surface of at least one virtual object in the virtual three-dimensional scene can be further calculated, and the world coordinates can be calculated by a screen ray difference method; the PW point is then converted into the local coordinates PL of the target cube model by the model matrix (Object2World) of the target cube model. Because the target three-dimensional texture has a corresponding relation with the target cube model and is suitable for a local coordinate system, the minimum coordinate of the PL local coordinate of the target cube model is (-0.5, -0.5, -0.5), and the minimum UV coordinate of the 3D texture is from (0,0,0), the local coordinate needs to be converted by (0.5,0.5,0.5) to obtain a three-dimensional texture sampling UV value, and the accuracy of a sampling result is ensured through coordinate conversion; and finally, rendering the ambient light shielding effect of the target model unit according to the three-dimensional texture sampling UV value.

By the ambient light shielding processing method in the embodiment, a target model unit of a target virtual object to be subjected to ambient light shielding processing can be obtained first, and then a target three-dimensional texture corresponding to the target model unit is obtained, wherein the target three-dimensional texture is obtained by prebaking the target model unit, and the size of the target three-dimensional texture is related to the size of a minimum bounding box of the target model unit; further, a target cube model of the target model unit may be acquired, the target three-dimensional texture may be rendered using the target cube model, and an ambient light shielding effect of the target model unit may be rendered according to the target cube model and the target three-dimensional texture. According to the technical scheme, the target three-dimensional texture is generated through prebaking, the influence of the model on the ambient light shielding of a scene is simulated by utilizing the volume information of the target three-dimensional texture, the real-time performance of the ambient light shielding effect can be ensured, the processes of subsequent three-dimensional texture rendering and ambient light shielding processing are accelerated, the performance consumption of the server during the ambient light shielding processing is reduced, the requirement of a game on the performance of game player equipment is reduced, the game can be normally run by using a low-profile machine, the running speed of the game can be increased, and good game experience is created for game users.

Further, as a refinement and an extension of the specific implementation of the foregoing embodiment, in order to fully describe the implementation of this embodiment, this embodiment further provides another ambient light shielding processing method, as shown in fig. 2, where the method includes:

201. and acquiring a target model unit of the target virtual object, wherein the target model unit is a model unit to be subjected to ambient light shielding treatment and is provided with a minimum bounding box.

202. And acquiring a target three-dimensional texture corresponding to the target model unit, determining main skeleton position coordinates of a skeleton part corresponding to the target model unit, and mapping the target three-dimensional texture obtained by pre-baking to the target model unit according to the main skeleton position coordinates so as to enable the movement of the target three-dimensional texture to be consistent with the movement of the target model unit.

The target three-dimensional texture is obtained by pre-baking the target model unit, and the size of the target three-dimensional texture is related to the size of the minimum bounding box of the target model unit. Specifically, when the target three-dimensional texture is prebaked through the target model unit, the minimum bounding box Rmin of the target model unit can be determined first, and further a new AABB target bounding box Rmax is generated according to the respective external extension E (assumed) distances in the X, Y, and Z axes of the minimum bounding box Rmin; baking the target model unit into an initial three-dimensional texture with the size of Rmax according to the size of the target bounding box Rmax; and then, carrying out fuzzy operation on the initial three-dimensional texture to generate an outer rubbing effect with fuzzy edges, storing the result into the 3D texture, storing Rmax information, and completing the prebaking of the target three-dimensional texture of the target model unit. Namely, the size of the target three-dimensional texture is equal to the size of the target bounding box after the minimum bounding box of the target model unit is extended, and the target three-dimensional texture comprises the model unit texture of the model unit and the edge extension texture of the extension area of the model unit.

Correspondingly, when the target three-dimensional texture is pre-baked, the embodiment steps may specifically include: respectively extending the minimum bounding box set by the target model unit upwards and outwards by preset distances according to X, Y and Z axes to obtain a target bounding box; generating an initial three-dimensional texture of the target model unit according to the target bounding box through prebaking; and carrying out convolution fuzzy processing on the initial three-dimensional texture to generate the target three-dimensional texture with fuzzy extension effect in the extension area of the target model unit. When convolution blurring processing is performed on the initial three-dimensional texture, convolution needs to be performed on three axes, namely X, Y and Z, corresponding to the target three-dimensional texture, and a specific convolution processing mode is the same as that of an existing two-dimensional image edge blurring processing mode, which is not described in detail herein. For the implementation, the convolution blurring processing is performed on the three-dimensional texture to expand the size of the three-dimensional texture, so that the ambient light shielding effect of the target three-dimensional texture can affect an object in contact with the target virtual object (for example, when the target virtual object is close to a wall, the back of the target model unit generates an ambient light shielding effect on the wall corresponding to the edge extension texture of the target three-dimensional texture).

For the embodiment, after the target three-dimensional texture corresponding to the target model unit is obtained, the main skeleton position coordinates of the skeleton part corresponding to the target model unit can be determined, and the target three-dimensional texture obtained by pre-baking is mapped to the target model unit according to the main skeleton position coordinates, that is, the creating of the binding relationship between the target three-dimensional texture and the target model unit is equivalent. The target three-dimensional texture can present a movement display effect consistent with the movement of the target model unit based on the binding relationship. By the method for decoupling the baking of the target three-dimensional texture from the action of the target virtual object, the baked target three-dimensional texture can be multiplexed, and the rendering efficiency of the target three-dimensional texture is improved.

203. The method comprises the steps of obtaining a target cube model of a target model unit, and determining world coordinates of an intersection point of the target cube model and at least one virtual object in a virtual three-dimensional scene, wherein the target cube model is used for rendering a target three-dimensional texture, the size of the target cube model is the same as that of the target three-dimensional texture, and the target cube model has a coordinate corresponding relation.

The world coordinates can be used to identify the world space position in the virtual environment where each virtual object is located, and the coordinates are represented by X, Y, Z, where Y represents the height of the virtual object from the base rock layer, and X and Z represent the position of the virtual object on the plane.

In a specific application scene, when determining the world coordinates of the intersection point of a target cube model and at least one virtual object in a virtual three-dimensional scene, the intersection point of a sight line in the target cube model and any virtual object except the target virtual object in the virtual three-dimensional scene can be calculated according to a sight line direction depth map, a screen ray is emitted from a corresponding point on a screen to the direction of the intersection point, the collision of a directional ray and other virtual objects is checked through the screen ray, and the world coordinates of the intersection point can be calculated based on a screen ray difference algorithm and the coordinates of the corresponding point on the screen. Correspondingly, the embodiment step 204 may specifically include: determining at least one intersection point of the target cube model and at least one virtual object in the virtual three-dimensional scene according to the sight direction depth map; the world coordinates of the intersection are calculated using a screen ray difference algorithm.

204. And calculating a three-dimensional texture sampling UV value of the intersection point based on the world coordinate and the coordinate corresponding relation, and rendering an ambient light shielding effect of the target model unit according to the three-dimensional texture sampling UV value, wherein the ambient light shielding effect is matched with the geometric form of the target model unit.

In a specific application scenario, when calculating a three-dimensional texture sampling UV value of an intersection point based on a world coordinate and a coordinate correspondence, embodiment step 204 may specifically include: converting the world coordinates into local coordinates of the target cube model by using a model matrix of the target cube model; and determining a three-dimensional texture sampling UV value corresponding to the local coordinate according to the corresponding relation of the coordinates.

Wherein the model matrix may be an Object2World matrix for transforming the vertex/direction vectors from the World space to the model space of the target cube model. After the local coordinates of the target cube model are obtained through conversion, since the minimum coordinates of the PL local coordinates of the target cube model are (-0.5, -0.5, -0.5), and the minimum UV coordinates of the 3D texture start from (0,0,0), the local coordinates need to be converted by (0.5,0.5,0.5) to obtain the three-dimensional texture sampling UV value, that is, the coordinate correspondence between the target cube model and the target three-dimensional texture is the coordinates of the target cube model plus (0.5,0.5,0.5) to obtain the coordinates of the target three-dimensional texture.

Correspondingly, when rendering the ambient light shielding effect of the target model unit according to the three-dimensional texture sampled UV value, embodiment step 204 may specifically include: acquiring a first pixel value of a target three-dimensional texture under a three-dimensional texture sampling UV value and a second pixel value of at least one virtual object under a world coordinate; performing positive film bottom-folding processing on the first pixel value and the second pixel value, and calculating a pixel shading value of at least one virtual object under world coordinates; rendering the at least one virtual object according to the pixel shading value to form an ambient light shading effect of the target model unit on the at least one virtual object. The positive film-on-bottom method is a darkening mode with high frequency, two homologous layers are mixed in a positive film-on-bottom mode, an image can be darkened in a smooth but nonlinear mode, and the obtained effect is that an object appears from the dark. Specifically, the pixel values of the two colors may be multiplied and then divided by 255 to obtain the pixel value of the final color. The negative copy-on-back mode is typically performed in a darker color than both of the original colors. Any color and black positive stack will get any black, any color and white positive stack will remain the same, and performing this mode with other colors will produce the effect of lighting in the darkroom with this color.

Correspondingly, when rendering at least one virtual object according to the pixel shading value to form the ambient light shading effect of the target model unit on the at least one virtual object, the embodiment steps may specifically include: rendering the second virtual object in dependence on the pixel shading values and a model of the second virtual object to form an ambient light shading effect on the second virtual object, wherein a dimmed version of the ambient light shading effect matches a geometric version of the target model cell. For example, the geometric shape corresponding to the target model unit is the foot shape, and the darkening shape of the ambient light shading effect is the sole shape of the virtual object; the geometry corresponding to the target model unit is the back shape, so the darkened shape of the ambient light shielding effect is the back shape of the virtual object.

In the method for processing ambient light shielding provided by this embodiment, a target model unit of a target virtual object to be processed by ambient light shielding may be first obtained, and then a target three-dimensional texture corresponding to the target model unit is obtained, where the target three-dimensional texture is obtained by pre-baking the target model unit, and the size of the target three-dimensional texture is related to the size of a minimum bounding box of the target model unit; further, a target cube model of the target model unit may be acquired, the target three-dimensional texture may be rendered using the target cube model, and an ambient light shielding effect of the target model unit may be rendered according to the target cube model and the target three-dimensional texture. According to the technical scheme, the target three-dimensional texture is generated through prebaking, the influence of the model on the ambient light shielding of a scene is simulated by utilizing the volume information of the target three-dimensional texture, the real-time performance of the ambient light shielding effect can be ensured, the processes of subsequent three-dimensional texture rendering and ambient light shielding processing are accelerated, the performance consumption of the server during the ambient light shielding processing is reduced, the requirement of a game on the performance of game player equipment is reduced, the game can be normally run by using a low-profile machine, the running speed of the game can be increased, and good game experience is created for game users.
