It will be appreciated that in the segmentation of the spatial region, a large voxel is first used as the starting point, where the large voxel is used as the spatial region from which the segmentation was originally performed, may be set based on a hierarchy of minimum spatial voxels, e.g., minimum spatial voxels 1 x1, the number of the layers of the space region is 3, the space region is 8 x 8, and the space region can be set in a self-defining mode. Then judging whether the space region contains an object or not before segmenting the large voxel, if yes, segmenting the large voxel, otherwise, not segmenting the large voxel, further respectively judging whether an object is in each sub-voxel according to two sub-voxels formed after segmentation, and if the object is the same, segmenting the sub-voxels, otherwise, not segmenting the sub-voxels, and forming a space voxel of one level after each voxel segmentation, wherein the size of the space voxel continuously decreases along with the increase of the level, for example, the space voxel of the first level, namely the large space voxel at the beginning, corresponds to the largest voxel, and the space voxel of the highest level, namely the space voxel corresponding to the space region after segmentation, corresponds to the smallest voxel, and the size of the voxel is doubled and reduced without adding one level, finally, grid data of a plurality of layers are formed after each space region is segmented, but the grid data is not uniform in layer distribution, only the space region around the object is segmented, and the layer distribution of the segmented space voxels is also not uniform, for example, for a space region of 8 x 8, the space region contains the position of the object at the upper left corner and is positioned at a second layer, 4 x 4 space voxels are formed after the first segmentation, namely, the space voxels of the first layer, for the space voxels of the first layer, only the space voxels containing the object are segmented into the space voxels of the second layer, namely, the other 3 space voxels positioned at the first layer are not segmented, 4 space voxels of 2x 2 are formed after the second segmentation, and similarly, for the space voxels of the second layer, only the spatial voxels containing the object are segmented into spatial voxels of the third level, and if all 4 spatial voxels on the second level contain the object, the spatial voxels of the third level formed after the segmentation of the 4 spatial voxels, i.e. each spatial voxel of the second level, form 41 x1 spatial voxels.

Because the level distribution in the grid data is uneven, in order to distribute the illumination probes with different densities in the game scene, the grid data of a plurality of levels can be traversed, the grid positions of the space voxels in the grid data of the plurality of levels are obtained for the space voxels containing the object, the effective illumination probes are arranged at the four vertexes of the grid positions, the first illumination probe grid of the space region is obtained, the space voxels are in different levels, repeated vertexes possibly appear, for example, the positions of the four vertexes of the space region are only in the first level, or in the second level or the third level in the segmentation process, the grid positions of the space voxels in the grid data of the plurality of levels are obtained, whether the effective illumination probes are arranged at the four vertexes of the grid positions is judged, if not, the virtual illumination probes are additionally arranged at the vertexes of the grid positions, the second illumination probe grid of the space region is obtained, so that the grid data of the level are filled with the effective illumination probes and the virtual illumination probes, for the purpose of using the virtual illumination probes, the virtual illumination probes is realized, the subsequent illumination probes can be used for seamlessly sampling the illumination information, and the subsequent illumination information is sampled in order to improve the illumination process.

Taking a 2D quadtree as a specific application scene for example, as shown in fig. 2a-2c, firstly taking the space voxels formed by the space region as the space voxels of the first level as shown in fig. 2a, then cutting the space voxels of the first level to form 4 space voxels of the second level, further judging whether the space voxels of each second level contain objects, if yes, cutting the space voxels of the second level until reaching the space voxels of the third level, secondly, adaptively setting illumination probes (effective illumination probes) in the space voxels until reaching the space voxels of the third level, as shown in fig. 2b, taking a solid circle as an effective illumination probe, putting the effective illumination probes at four corners of the space voxels of the first level as the space voxels contain objects, and putting the effective illumination probes at four corners of the space voxels of the first level as the space voxels of the second level, wherein if the effective illumination probes are positioned at the same position, and the virtual illumination probes are not positioned at the same position as the virtual illumination probes, and the virtual illumination probes are not positioned at the virtual intersection point, and the virtual intersection point is not formed by the virtual illumination probe, if the virtual intersection point is not positioned at the virtual intersection point, and the virtual intersection point is formed by the virtual illumination probe is not positioned at the virtual intersection point, and the virtual intersection point is formed by the virtual intersection point.

Further, as the acquisition process of the illumination information is influenced by the illumination detection positions in the illumination probe grid, the illumination information of different space positions is also influenced by each other, the space logic relation mapped by the illumination information in the second illumination probe grid is extracted and stored in the texture resource information before the illumination information is rendered, then the illumination information in the texture resource information is unfolded into the three-dimensional block data set according to the space logic relation in the process of rendering the illumination information, the hierarchical relation among the three-dimensional block data sets is recorded by utilizing the indirect texture, the three-dimensional block texture information of the tree structure is formed by further utilizing the hierarchical relation among the three-dimensional block data sets in the indirect texture, the space position of the illumination information in a game scene is recorded in the three-dimensional block texture information, the viewpoint position is equivalent to the space position corresponding to the view angle of video equipment according to the space position of the viewpoint, the space position is taken as the illumination acquisition position, the illumination information of the corresponding space position is read from the three-dimensional block texture information of the three-dimensional block structure, the space relation is stored in advance, the space relation is not required to be used, and the large-scale storage and the cost of the data is saved, and the data is transmitted simultaneously, and the data is rendered and the accuracy is guaranteed.

Further, considering the distribution condition of the effective illumination probes and the virtual illumination probes in the second illumination probe grid, in the process of expanding illumination information in texture resource information into three-dimensional block data sets according to a space logic relationship and recording the hierarchical relationship between each three-dimensional block data set by using indirect textures, firstly extracting the hierarchical distribution of the effective illumination probes and the virtual illumination probes in the second illumination probe grid according to the space logic relationship, then expanding illumination information in the texture resource information into the three-dimensional block data according to the hierarchical distribution of the effective illumination probes and the virtual illumination probes in the second illumination probe grid, and recording the hierarchical relationship between the three-dimensional block data sets by using indirect textures. Because indirect texture is not direct texture information, a large amount of texture information is not required to be transmitted in the process of transmitting texture resource information, so that the transmission efficiency and sampling efficiency of illumination information in the subsequent rendering process are improved.

Further, in order to accurately acquire actual illumination information in the game world, in the process of reading illumination information of corresponding spatial positions from three-dimensional block texture information of a tree structure according to the spatial positions of viewpoint positions in the game scene for rendering, firstly, according to the spatial positions of the viewpoint positions in the game scene, indirect textures representing the hierarchical relationship between three-dimensional block data sets are acquired from the three-dimensional block texture information of the tree structure, and then, the illumination information of the corresponding spatial positions in the three-dimensional block texture information of the tree structure is read for rendering by utilizing the indirect textures representing the hierarchical relationship between the three-dimensional block data sets. Because the indirect texture stores the level and the offset of the three-dimensional block data in the tree structure, the illumination information acquired by the effective illumination probe can be acquired by sampling the corresponding level and the offset in the indirect texture according to the world space position of the screen pixel.

The embodiment provides another method for rendering illumination information in a game scene, as shown in fig. 3, the method is applied to a client of a scene rendering tool, and includes the following steps:

201. a close-range voxel contained in a spatial voxel in the game scene is acquired.

The game is real-time, dynamic and interactive computer simulation, many three-dimensional games use three-dimensional triangular grids to express the object surface, the detail layers of the expressed object surface are stored in textures, when coloring is carried out, the object with the intersecting light rays needs to be considered firstly, then multi-level textures of the detail layers corresponding to the object surface are selected for coloring calculation, a space voxel is used as a volume unit for rendering the textures in the game space, and an object containing the space voxel can be represented by three-dimensional rendering or extracting a polygon isosurface with a given threshold contour.

For illumination effects related to game scenes, global illumination is generally used for rendering, direct light and diffuse reflection effects as much as possible are considered by the global illumination, and finally, the presented shadow effect is closer to the real world. The specific global illumination refers to calculation of reflection of light rays around a game scene, and is responsible for making metal reflection effects realizing a plurality of fine coloring special effects, atmospheres and gloss in the environment. In the existing global illumination mode, all indirect illumination is pre-calculated and stored in texture information of a ray map, and the ray map enables a game scene to have an effect similar to global illumination. The illumination probe can simulate the effect of using the illumination map aiming at the global illumination of a non-static object, can sample illumination information of a certain appointed point illuminated in the 3D space in a pre-calculation stage before operation, and then compiles and packages the collected information through spherical harmonics. These illumination information encodings can be quickly reconstructed out of the illumination effect by the shader program while the game is running. Similar to the illumination map, the illumination probe stores illumination information in the scene, but the illumination map stores illumination information of the light illuminating the surface of the object, and the illumination probe stores illumination information of the light passing through the vacuum area.

The space voxels in the game scene correspond to three-dimensional space units in the game world, the near-distance voxels are voxels meeting distance conditions in voxels of a preset level formed by dividing the space voxels in the game scene, the distance conditions are equivalent to voxels close to the surface of an object, the distance conditions serve as the basis for judging the voxels close to the surface of the object, bounding boxes of the voxels can be intersected with the bounding boxes of the object in the game scene, the pixels to be divided and the divided pixels can be judged according to the distance conditions through the fact that the space voxels can be formed in the dividing process, and if the bounding boxes of the voxels intersect with the bounding boxes of the object in the game scene, the voxels are indicated to be close to the surface of the object, namely the near-distance voxels.

In the embodiment of the application, for placing the illumination probes in the game world, the illumination probes are usually manually placed, the placing position is adjusted according to the rendering result of the actual illumination information, the time and space waste is serious, the probes cannot effectively cover along the object surface, the area of the object surface can be positioned from the game world by acquiring the close-range voxels contained in the space voxels in the game scene, and the illumination probes are adaptively arranged aiming at the area of the object surface, so that the illumination information with more environmental influence in the game scene is acquired, and the sampling efficiency of the illumination information is improved.

The execution body of the embodiment can be a rendering device or equipment of illumination information in a game scene, and the execution body can be configured at a client of a scene rendering tool, after the game scene is arranged, the position information of an illumination probe in the game scene is required to be arranged, because the illumination probe cannot be directly mounted on a game object, the execution body generally needs to depend on a designated space area in the game scene, when the illumination probe is added into the game scene, a close-range voxel contained in a space pixel in the game scene can be acquired aiming at the designated space area, the position of the close-range voxel in the game scene is used as a preferred position for placing the illumination probe, the illumination information which meets the requirements of the game scene better can be acquired, and the illumination rendering effect is improved.

202. And creating an effective illumination probe and a virtual illumination probe for the short-distance voxels contained in the space voxels, and generating a probe grid of the space voxels.

The virtual illumination probes are illumination collectors which are arranged at sampling points with real positions in the game world, can capture light rays from all directions at the sampling points, encode color information of the captured light rays into a group of coefficients which can be rapidly evaluated in the game running process, and because space pixels contain short-distance voxels of preset levels, in order to ensure interpolation effects of sampling illumination information of the effective illumination probes arranged between different levels, the virtual illumination probes can effectively interpolate and transition to form an added illumination collector when the auxiliary effective illumination probes are sampled by the GPU, so that seamless interpolation can be provided for sampling between voxels of a larger level and voxels of a smaller level in the game scene.

In the embodiment of the application, the probe grids of the space voxels are equivalent to grids of a tree structure, wherein the tree structure is a preset level formed by space voxel segmentation, for example, the octree structure corresponds to a preset level of 3, namely, the space voxels are segmented into 8 voxels, the corners of each voxel form 2 x 2 probe grids, in order to distribute illumination probes with different densities in the game world, and the total number of the creation is adaptively minimized, when the space voxels are segmented, close-range voxels are recorded, the close-range voxels have better illumination information sampling effect, and effective illumination probes are further created on the close-range voxels.

It can be appreciated that while the effective illumination probe can provide illumination information with interpolation effect, it still needs more than gigabytes of resources occupation, in order to be able to cope with various scale and types of game scenes and reduce the resources occupation, by adding a virtual illumination probe between different levels of space pixels, the virtual illumination probe can correlate the effective illumination probes in each level, and sample the sampling interpolation results with different densities according to the effective illumination probe in different space pixels in the game world, so as to reduce the resource expense of the illumination information collection process.

203. And merging and storing illumination information captured by the probe grid of the space voxel into texture resource information according to the viewpoint position in the game scene.

The method comprises the steps that a viewpoint position in a game scene is any sampling position of illumination information in the game scene, an effective illumination probe continuously collects illumination data changing in the game scene according to the viewpoint position, then in the interpolation process of the illumination data, sampling interpolation results with different densities are provided for the illumination data collected by the effective illumination probe by utilizing a virtual illumination probe, so that illumination information captured by a probe grid is formed and combined and stored in texture resource information.

It will be appreciated that the illumination information captured by the probe grid of spatial voxels comprises pre-computed illumination data, and that much of the budget overhead is generated when compiled, but not when running, the illumination probe will store the illumination data across the scene space and integrate it into texture resource information, which corresponds to the illumination map of the dynamic object, also comprising direct light sources projected onto the object surface within the scene, and indirect light sources reflected between different objects, the surface information and the relief information of the object being described by the colorants on the object material.

204. And responding to a rendering instruction of the illumination information, establishing a rendering task by utilizing the texture resource information, and rendering the illumination information in the game scene.

As the texture resource information can be used for accurately and currently using the illumination information in the game scene, a rendering task is further established by using the texture resource information, and the illumination information in the game scene is rendered. It will be appreciated that in the same manner, each scene data frame in the game scene will create a rendering task, and the scene space in the game scene is submitted to the rendering queue by the scene rendering tool once, and each renderable scene space, in addition to its own mesh, material, bounding box, its matrix in the game scene, and so on.

Compared with the prior art that illumination information is sampled by object, the method for rendering illumination information in the game scene can provide indirect illumination for a large number of complex objects, is suitable for various illumination acquisition scenes, and avoids the limitation of the update cost and the transmission bandwidth of 3D textures from a CPU end to a GPU end on the total number of objects sampled by object. Compared with the prior art that illumination information is sampled pixel by pixel, the method and the system have the advantages that the short-distance voxels contained in the space voxels in the game scene are obtained, the short-distance voxels are the voxels close to the surface of the object, a larger number of illumination probes are needed, effective illumination probes and virtual illumination probes are further created for the short-distance voxels contained in the space voxels, probe grids of the space voxels are generated, the illumination probes and the virtual illumination probes can be adaptively distributed, the virtual illumination probes are used as auxiliary effective illumination probes, seamless interpolation is provided for the game scene, illumination information captured by the probe grids of the space voxels is combined and stored in texture resource information according to viewpoint positions in the game scene, the texture resource information can cope with illumination information sampling of different game scenes, so that the same-screen pixels can sample interpolation results of different surface densities according to different spatial positions, further, when a rendering instruction of the illumination information is responded, a rendering task is established by using texture resource information, three-dimensional texture addresses of the game scene are cached, the number of the pixel texture probes in the game scene is determined, the number of the illumination probes is greatly increased, the illumination information of the game scene is saved, the illumination information is saved by the aid of the texture probes, the image processing efficiency is greatly, the illumination information is saved, the illumination information is required to be adaptively transmitted by the GPU, the illumination information is saved, and the image processing cost is reduced, and the illumination information is required to be sampled by the image processing, and the image processing cost is greatly is reduced.

Further, as a refinement and extension of the specific implementation manner of the foregoing embodiment, in order to fully describe the specific implementation process of the present embodiment, the present embodiment provides another method for rendering illumination information in a game scene, as shown in fig. 4, where the method includes:

301. And acquiring a space region covered by an object to be hung in the game scene, and dividing each space voxel in the space region into voxels of a preset level.

The game scene consists of objects, some of which are solid, e.g. a brick, and some of which have no fixed shape, e.g. a strand of smoke, but all of which occupy the volume of three-dimensional space, and which may be opaque, i.e. light cannot pass through the object, or transparent, i.e. light can pass through the object. When an opaque object is rendered, only the surface of the opaque object needs to be considered, the internal part of the object does not need to be known, and when a transparent or semitransparent object is rendered, the behaviors such as reflection, refraction, scattering, absorption and the like caused when light passes through the object need to be considered, and the internal structure and attribute knowledge of the object need to be combined.

The light in the game scene can control the activity of the character, influence the mood of the player and influence the mode of sensing various events, and the game engine can be used as a tool for game development, so that various effects which are observed in real time in the process of game production, including intensity, color, shadow and the like, can be flexibly adjusted in the process of production. In general, for static objects in a game scene, global illumination may be used to bake an illumination map, and when an illumination map is baked, objects in the game scene calculate a result of the map based on the effect of light, and the result of the map is superimposed on objects in the game scene to create a lighting effect, where the illumination map may include direct light sources projected onto the surfaces of the objects in the scene, and indirect light sources reflected between different objects, and surface information and concave-convex information of the objects may be described by a shader on the material of the objects. Although the illumination map of the static object cannot change the illumination condition of the game scene when the game is executed, the pre-calculated real-time global illumination system can calculate complex scene light source interaction in real time, and the game environment with rich global illumination reflection can be established and the change of the light source can be reflected in real time through pre-calculating the global illumination. For dynamic objects in a game scene, sampling points of illumination probes can be arranged in a designated area to collect light and shade information of the designated area, the designated area can be a space area covered by an object to be hung in the game scene, and due to less illumination information generated in a place with small illumination change in the game scene, waste is generated when too many illumination probes are arranged, and dense illumination probes are arranged at illumination change, shadow positions and illumination transition areas at preferred positions. The corresponding preferred position can be selected for the space region covered by the to-be-hooked region, each space voxel in the space region is divided into voxels of a preset level, the preset level is a limiting depth of a tree structure, the limiting depth can be specifically set according to an actual application scene, and the higher the number of levels, the more the number of required illumination probes.

302. And traversing each voxel in the preset level, and judging that the bounding box of the segmented voxel intersects with the object bounding box in the game scene.

It can be understood that, in order to arrange more illumination probes at the spatial pixels close to the surface of the object, and arrange less illumination probes at the open spatial pixels, for each voxel in the preset hierarchy, the distance condition determination is performed on the voxel, where the bounding box of the segmented voxel is equivalent to the smallest hexahedron that encloses the segmented voxel and is parallel to the coordinate axis, the object bounding box in the game scene is equivalent to the smallest hexahedron that encloses the object and is parallel to the coordinate axis, the bounding box has a simple structure and small storage space, is not suitable for a complex virtual environment containing soft deformation, and by determining whether the bounding box of the segmented voxel intersects with the bounding box of the object in the game scene, whether the object exists in the spatial voxel, the spatial voxel corresponding to the object does not need to be segmented, and the illumination probes do not need to be arranged.

303. If yes, determining the segmented voxels as close-range voxels of the object surface in the game scene.

The above-mentioned determination process may be performed before and after the division of the spatial voxels, and repeatedly dividing the voxels conforming to the determination condition, and if the voxels do not conform to the determination condition, the division is not performed, first, starting with a large voxel as an original spatial voxel to be divided, and then uniformly dividing the same, where the division principle is that if the voxels are close to the object surface, the division is performed, and repeatedly dividing each sub-voxel until reaching a specified minimum voxel size, that is, a preset level, where the process generates a tree structure of the preset level.

304. And creating an effective illumination probe and a virtual illumination probe for the short-distance voxels contained in the space voxels, and generating a probe grid of the space voxels.

In the embodiment of the application, the effective illumination probe is used as the illumination probe arranged in the game scene, and is generally close to the object surface to acquire the illumination brightness condition of the object surface, specifically, the effective illumination probe can be created for the close-range voxels in the hierarchy in the space voxels, the virtual voxels corresponding to the hierarchy are added for the space voxels, the virtual illumination probe is created for the voxels conforming to the addition condition in the virtual voxels, and the virtual illumination probe is used for carrying out seamless interpolation on the illumination data sampled by the close-range voxels in the hierarchy in the space voxels.

Specifically, in the process of adding a virtual voxel corresponding to a level for a space voxel and creating a virtual illumination probe for a voxel conforming to an addition condition in the virtual voxel, a virtual voxel corresponding to a level greater than first-order in the space voxel is added, the virtual voxel is mapped with a voxel corresponding to the level in the space voxel, the virtual voxel corresponding to the level is further traversed, whether an effective illumination probe exists in the mapped voxel in the space voxel is judged, and if not, the virtual illumination probe is created for the virtual voxel. The virtual voxels and the virtual illumination probes can be displayed in different colors for voxels of different levels, and the virtual illumination probes are additionally built for the different levels, so that the virtual illumination probes are additionally built for places around the close-range voxels where the effective illumination probes are built and the effective illumination probes do not exist.

305. And expanding illumination information captured by the probe grid of the space voxel to a three-dimensional block data set according to the viewpoint position in the game scene to form three-dimensional block texture information of a multi-level tree structure.

In the embodiment of the application, the effective illumination probes in the probe grid can be used for sampling illumination data in the game scene, interpolation operation is carried out on the illumination data to obtain first illumination information of the viewpoint position in the game scene, the virtual illumination probes in the probe grid are used for carrying out seamless interpolation on the illumination data sampled by the close-range voxels in the space voxels in the hierarchy to obtain second illumination information of the viewpoint position in the game scene, and the first illumination information and the second illumination information of the viewpoint position in the game scene are further unfolded to a three-dimensional block data set to form three-dimensional block texture information of a multi-level tree structure.

It should be noted that, the three-dimensional texture information of the tree structure combines the illumination information captured by the effective illumination probe and the virtual illumination probe, and can transmit the illumination information to the GPU to form the information of the cultural resources.

306. And in the process of expanding the three-dimensional block data set, recording the hierarchical relation mapped by the three-dimensional block data set into indirect texture information.

It should be noted that, in order to complete the storage of the three-dimensional block data set, it is also necessary to construct an indirect texture information including a hierarchical expansion representation by using a tree structure, and during operation, the indirect texture information is sampled, and the obtained content is the hierarchical relationship of the three-dimensional block data in the tree structure, so as to calculate the sampling position of the buffer illumination probe in the three-dimensional block data.

307. And merging the three-dimensional block texture information and the indirect texture information and storing the merged three-dimensional block texture information and the indirect texture information into texture resource information.

It will be appreciated that the texture resource information stores illumination information in each spatial voxel in the game scene, and then interpolation is performed between illumination information captured by baking to the nearest illumination probe, and illumination information located at any position in the spatial voxel is projected onto the moving object after estimation.

308. And responding to a rendering instruction of the illumination information, establishing a rendering task by utilizing the texture resource information, and rendering the illumination information in the game scene.

In the embodiment of the application, a rendering task can be established by utilizing texture resource information, a hierarchical relation of three-dimensional block texture information mapping is obtained from indirect texture information, then the position information of the three-dimensional texture information in a tree structure is queried according to the hierarchical relation of the three-dimensional block texture information mapping, finally the illumination information captured by a probe grid of a spatial voxel is sampled from the three-dimensional block texture information according to the position of the three-dimensional texture information in the tree structure, and the illumination information is rendered.

Specifically, in the process of inquiring the position information of the three-dimensional texture information in the tree structure according to the hierarchical relation of the three-dimensional block texture information mapping, the hierarchy and the offset of the three-dimensional block texture information in the tree structure can be extracted according to the hierarchical relation of the three-dimensional block texture information mapping, and the position information of the three-dimensional texture information in the tree structure can be calculated according to the hierarchy and the offset of the three-dimensional block texture information in the tree structure.

Taking a 2D quadtree as a specific application scene for example, firstly, adaptively creating an effective illumination probe in space voxels in a game scene, then placing an effective illumination probe in each voxel corner, specifically dividing each space voxel into 4 voxels, further repeatedly dividing each voxel, forming the space voxels into an octree structure to form a2 x2 probe grid, recording voxels close to the surface of an object, placing the effective illumination probe on the voxel nodes, then adding virtual voxels and virtual illumination probes at the corresponding level of the space voxels in the game scene, realizing seamless interpolation of illumination information when sampling between voxels of a larger level and voxels of a smaller level, further combining illumination information captured by the effective illumination probe and the virtual illumination probe and storing the illumination information captured by the virtual illumination probe into texture resource information, the texture resource information can be expanded layer by layer in the rendering process, each three-dimensional block data in the texture resource information of each layer has an independent number, the three-dimensional block data of each layer is usually combined with the illumination information captured by the effective illumination probe and the virtual illumination probe, the combination processing can be continued for the three-dimensional block data which are not combined and stored, as the expanded three-dimensional block data set is composed of a storage structure which is composed of a plurality of textures with the same block size layout, the storage structure can realize indirect addressing in the rendering process, so that after the three-dimensional block data caching is completed, the three-dimensional block data can be acquired from the cache, the whole rendering process is as shown in fig. 5a-5b, the tree structure is utilized to construct indirect textures which are expanded layer by layer, the indirect textures are sampled in the rendering process, the obtained content is the level and the offset of the three-dimensional block data cached in the tree structure, so that the sampling position for the illumination probe in the block cache can be calculated.

According to the embodiment of the application, spatial voxels with hierarchical relations in a tree structure are unfolded to form an illumination probe set to form a three-dimensional block data set, the hierarchical relation of each three-dimensional block data in the tree structure is stored in an indirect mapping texture, then in the game scene rendering process, each frame of scene data updates illumination information captured by an illumination probe in the tree structure according to viewpoint positions and is unfolded to the three-dimensional block data set, the hierarchical relation is recorded to the indirect texture in the unfolding process and is then transmitted to a GPU, when sampling is performed, according to the world positions of sampling points on the surface of an object, a certain hierarchical relation in the corresponding tree structure is obtained from the indirect texture, and finally illumination information formed by sampling a final illumination probe in the three-dimensional block data is utilized to render the illumination information.
