In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present disclosure. One skilled in the relevant art will recognize, however, that the aspects of the disclosure may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

The following describes the technical scheme of the embodiments of the present disclosure in detail:
conventional forward rendering pipeline renders n objects colored under m light sources, requiring m x n times of rendering, and performance is greatly degraded as the number of objects and light sources in a scene increases. In one solution idea provided by the inventor, the light source may be processed by a block-based rendering method, and the block-based rendering (Tile Based Rendering) is to pre-render the depth of the scene, then divide the screen space into multiple tiles (grids), for example, 32×32, and calculate which tiles are affected by the light source according to the scene depth data, thereby performing illumination coloring on each tile. Although block-based rendering can reduce the complexity of the algorithm, the depth of the scene needs to be obtained first, which doubles the number of Draw calls (commands for the CPU to Call the image programming interface) and is unacceptable for mobile platforms. In another solution idea provided by the inventor, the Draw Call can be avoided by calculating the depth of the previous frame, but the screen flicker can be caused by delaying one frame calculation, and the rendering error can occur if the player lens moves fast, so that the rendering effect is poor.
In view of one or more of the above problems, the present exemplary embodiment provides a virtual light source processing method. Referring to fig. 1, the method may include the steps of:
step S110: and dividing the virtual scene to obtain a plurality of division blocks of the virtual scene.
Step S120: and acquiring a plurality of light sources in the current visual field range, and determining texture information of each divided block according to the light source information of each light source.
Step S130: and determining the illumination effect of each divided block by using the texture information of each divided block.
In the virtual light source processing method provided by an example embodiment of the present disclosure, a virtual scene is converted into a plurality of partition blocks by partitioning the virtual scene, so that texture information of each light source for each partition block is determined, and compared with coloring each light source through a rendering pipeline, algorithm complexity is greatly reduced, and processing efficiency can be improved; in addition, the scene depth data does not need to be processed, so that the resource consumption can be reduced, and the application range is wider.
Next, the above steps of the present exemplary embodiment will be described in more detail.
In step S110, a virtual scene is divided, and a plurality of divided blocks of the virtual scene are obtained.
The virtual scene includes a three-dimensional or multidimensional space, and most of the game scenes do not have too large visual changes in the vertical direction, so that the virtual scene can be divided from the horizontal direction, for example, the virtual scene is divided according to the x-z direction (horizontal direction) of the spatial bounding box of the virtual scene, thereby obtaining a plurality of division blocks. The equally sized divided blocks can be obtained by uniform division, and the specification of the divided blocks can be determined according to the actual size of the virtual scene, for example, 32×32, 64×64, 128×128, or the like, or other specifications, for example, 8×8, or the like, according to the requirements, which is not particularly limited in this embodiment. The virtual scene can be converted into the 2D partition blocks through the partition, so that the complexity of an algorithm is reduced, the calculation efficiency is improved, the problem of light source overlapping in the horizontal direction can be solved by dividing the virtual scene in the horizontal direction, and a better illumination effect is realized.
In step S120, a plurality of light sources within the current field of view are acquired, and texture information of each of the divided blocks is determined according to the light source information of each of the light sources.
The current field of view refers to a range of a scene displayed on the current display screen, and a light source within the coordinate range can be acquired from the coordinate range currently displayed. Each element in the virtual scene has unique coordinates, so that the coordinates of all the light sources can be obtained, and the light sources in the current field of view can be determined. And, along with the operation of the user, the current visual field range of the user can be correspondingly changed, and the light source can be dynamically changed, for example, the current visual field range of the user is shifted out, if the current visual field range of the user is detected to be changed, the light source which falls in the visual field range after the change can be acquired again, and the update of the light source is kept. The light source information is information defined by a developer when the virtual scene is developed and designed, and specifically may include attribute information of the light source, such as an identification number, coordinates of the light source in the virtual scene, a light source type, a light source color, illumination intensity, and the like, and may also include other information, such as illumination attenuation information, illumination shape, and the like, which is not particularly limited in this embodiment.
The texture information may be used to determine the illumination effect on the divided blocks, and may specifically include index information of the light sources corresponding to the divided blocks, so that the illumination effect of the divided blocks is determined by the index information, for example, the index information of the divided block a is the light sources a, b, c, e, the four light sources, and the like; attribute information of the light source, such as light source color, a map corresponding to the light source, and the like, may also be included; the method can further comprise the illumination characteristics of the divided blocks, and the illumination characteristics can be used for determining the images of the illumination effects corresponding to the divided blocks. The light source information can be obtained by accessing the resource catalog corresponding to the virtual scene, and then the illumination characteristics of the light source for each divided block are calculated. Specifically, the color and the type of the light source can be determined through the light source information, the attenuation change of the light source of different types can be different, the more illumination is obtained from the dividing block which is closer to the light source, the distance between the dividing block and the light source can be calculated through the coordinates of the light source and the coordinates of the dividing block, and then the illumination characteristic under the distance is calculated through an illumination attenuation algorithm. And traversing each piece of light source information in the current visual field range in sequence, determining the illumination characteristics of the light source information for each divided block, and obtaining texture information on each divided block after traversing all the light source information in the current visual field range. For example, if the current field of view includes 5 light sources, for dividing the block a, the illumination characteristics a, b, c, d, e of each light source are sequentially calculated, so as to obtain texture information of a.
In an exemplary embodiment, the method may include step S201 and step S202, as shown in fig. 2, wherein:
in step S201, the illumination range of each light source is obtained from each light source information. The scope of care may refer to a range of sizes of the scene affected by the illumination of the light source. Specifically, the coordinates of the light source and the illumination type of the light source can be queried according to the light source information, so that the illumination range of the light source is determined, for example, if the coordinates of the light source are O, the illumination type is circular, and the corresponding illumination range is O+r, wherein r is the illumination radius. In addition, the illumination range of the light source can be obtained in other manners, for example, the size range affected by the light source is queried from the light source information, and then the partition blocks within the size range are determined according to the coordinates of the light source, so that the illumination range is obtained.
In step S202, from the plurality of light sources, determining a light source corresponding to each of the divided blocks according to the illumination range, so as to obtain texture information of the divided blocks according to the light source corresponding to the divided blocks. Specifically, determining the illumination range of each light source in the current field of view can determine the partition block affected by illumination of each light source, for each partition block, if the partition block is within the illumination range of one light source, determining that the partition block corresponds to the light source, traversing each light source to obtain all the light sources corresponding to the partition block, and storing all the corresponding light sources as texture information of the partition block. For example, for the partition block 1, when the illumination effect of the light sources a, c, f is received, the texture information of the partition block 1 may be the illumination information of the light sources a, c, f. Specifically, the method for determining the light source corresponding to each divided block may include the following steps S301 to S303, as shown in fig. 3, where:
In step S301, a bounding box of the divided blocks included in the current field of view is determined. For example, as shown in fig. 4, when the camera is determined as the starting point P0 and the current center of view P1 is configured with P1 as the center of the circle, a bounding box 401 may be obtained, where V0 is the direction of the line of sight of the camera. The actual size of the bounding box can be determined by the size of the partition block and the size of the texture image, and assuming that the size of the partition block is N and the size of the texture image is M, the coverage of all the partition blocks is nxm, for example, 128×128 for the texture image and 2 meters for each partition block, the coverage of the bounding box is 256 meters×256 meters. Since the scene outside the visual field range is not displayed currently, only the light sources corresponding to the dividing blocks in the current visual field range are calculated, so that the calculated amount is reduced, and the calculation efficiency is improved.
In step S302, for each light source, an intersection of the bounding box with the illumination range of the light source is calculated. The illumination range comprises the divided blocks affected by the light source, and the divided blocks affected by the light source in the divided blocks in the current field of view can be obtained through intersection operation of the illumination range and the divided blocks in the current field of view. For example, point light sources and spotlights are exemplified. As shown in fig. 4, if the shape of the point light source is a circle, after the circle is obtained from the light source information, performing intersection operation on the circle and the bounding box of the dividing block of the current field of view, where the intersection obtained is the illumination range of the point light source, as shown in fig. 5; and if the shape of the spotlight is triangular, performing intersection operation on the triangle and a bounding box in the current field of view to obtain the illumination range of the spotlight, as shown in fig. 6.
In step S303, if the divided block is included in the intersection, the divided block is corresponding to the light source. After the intersection of the illumination range of each light source and the current field of view is obtained by calculation, each divided block in the current field of view is judged, and the intersection containing the divided block is determined, for example, 10 light sources respectively obtain 10 intersections, and a divided block 1 is contained in intersections 1, 2 and 5, then the light sources respectively corresponding to 1, 2 and 5 are corresponding to the divided block 1 and are stored as texture information of the divided block 1.
Furthermore, it can be seen that the same divided block may be simultaneously affected by the illumination of a plurality of light sources, i.e. the divided block may correspond to a plurality of light sources. In the exemplary embodiment, determining the light source corresponding to the divided block further includes the following step S701 and step S702, as shown in fig. 7, where:
in step S701, it is determined whether the number of corresponding light sources included in the texture information of the divided block is a preset value. When determining the light sources corresponding to the divided blocks, the number of the light sources corresponding to the current time can be recorded through a parameter, namely, each time one light source is stored in the texture information of the divided blocks, the value of the parameter is added with 1, and then the parameter is judged, so that whether the value is a preset value or not is judged. The preset value may be determined according to actual requirements, for example, 4, 5, 6, etc., or may be other values, for example, 2, 8, etc., which is not limited in this embodiment.
In step S702, if the number of the corresponding light sources is a preset value, a light source to be discarded is selected from the corresponding light sources, so as to delete the light source to be discarded. If the number of the corresponding light sources is a preset value, the candidate new light sources needing to be added can be deleted. Because the index texture is 4 channels, the texture information of each light source can accommodate 4 indexes, so that the preset value can be 4, and when the light source corresponding to the divided block is greater than 4, the light source can be selected for deletion, so that the resource waste is reduced, and the power consumption is reduced.
The method for selecting the light source to be discarded from the corresponding light sources may include the following steps S801 to S803, as shown in fig. 8, specifically:
in step S801, the light source position and intensity of each corresponding light source are obtained from the light source information of each corresponding light source. The light source information can comprise coordinates and intensity parameters of the light sources, so that the positions and the intensities of the light sources can be obtained by inquiring the light source information of the light sources; or, corresponding intensity can be set for each type of light source in advance, and then the corresponding intensity of the light source type is searched according to the light source type of the light source. The farther from the light source position the less illumination is obtained, i.e. the illumination intensity decays with increasing distance.
In step S802, a contribution value of each of the corresponding light sources is calculated using the light source positions and intensities. For example, the contribution value of the corresponding light source on each divided block can be calculated by using the inverse square law of physics; the light attenuation algorithm may be calculated by other light attenuation algorithms or by a custom algorithm, which is not particularly limited in this embodiment.
In step S803, a light source to be discarded is selected from the already corresponding light sources according to the contribution value. For example, after the illumination contribution of the corresponding light source to the divided block is obtained, a reservation with a larger contribution can be selected, and the light source with the smallest contribution is used as the light source to be discarded for deletion. After deleting the light source with small contribution, a new light source can be added, so that the light source in the texture information of the divided blocks does not exceed a preset value, thereby being beneficial to reducing the artifact and improving the display effect.
For example, after determining the light sources corresponding to the divided blocks, traversing the light source information of each light source, and writing the light source information of each light source into the texture information, where the format of the texture information may be RGBA. Fig. 9 shows a data structure of texture information, in which light source information of a plurality of light sources is stored, as shown in fig. 9, four channels of one pixel may correspond to four light sources, and each channel may be 8 bits, and 255 light sources may be represented. Wherein, the LightPosIndRadius, four floating point numbers (float 4) can represent the position information (such as x, y, z) of the light source and the radius of the light source; lightColor, which may represent the color of the light source; spotDir, which may represent the direction of the spotlight; spotengles, which may represent the inside and outside angles of a spotlight, is used to calculate the light attenuation of the spotlight. In this embodiment, the process of determining texture information of the divided blocks runs on the CPU, and compared with the process of calculating on the GPU, the process has lower requirements on hardware, and is more convenient for debugging and expansion.
Next, with continued reference to fig. 1, in step S130, the illumination effect of each of the divided blocks is determined using the texture information of each of the divided blocks.
After the texture information on each divided block is determined, the illumination effect can be calculated according to the texture information when the virtual scene is rendered. For example, the illumination effect may be calculated in the Pixel loader, and first, the UV coordinates corresponding to the texture information may be calculated using the coordinates of the divided blocks, the sizes of the divided blocks, and the spatial coordinates of the pixels, so as to obtain the light source data in the texture information, and the RGBA values of the pixels are calculated by using the light source data, so as to obtain the illumination effect of the pixels. Specifically, the method may include steps S1001 to S1003, as shown in fig. 10, in which:
in step S1001, a target light source corresponding to each divided block is obtained from the texture information. Since the index information of each light source is stored in the texture information, the target light source corresponding to each divided block can be determined from the texture information. In addition, the partition block may not include texture information, and it may be determined whether the texture information includes a light source by a parameter, if the partition block is not affected by illumination of any light source, the value of the parameter may be determined to be 0, if the partition block is affected by the light source, the value of the parameter may be set to 1, if the value of the parameter is 0, it may be determined first when the target light source is acquired, and if the value is not 0, the target light source included therein may be acquired, thereby reducing the amount of computation.
In step S1002, a light source type of the target light source is acquired from light source information of the target light source. The light source information of the target light source may include a light source type of the target light source, for example, a point light source, a spotlight, etc., and different light source types are different in illumination conditions, so that the light source type of the target light source is obtained so as to calculate the illumination effect according to the light source type.
In step S1003, an illumination attenuation algorithm is determined by the light source type to calculate the illumination effect of the target light source for each of the divided blocks. In this embodiment, a plurality of light source types, for example, a point light source, a spotlight, or other types customized, etc., may be predetermined, and then a lighting attenuation algorithm corresponding to each light source type may be determined, where the lighting attenuation algorithm may include a physical theorem, or may include a customized method, for example, a linear attenuation of the lighting intensity with distance, etc., and the embodiment is not limited thereto. The RGBA value of the pixel contained in each divided block can be calculated through the illumination attenuation algorithm, so that the illumination effect on the pixel is determined. Specifically, the method for determining the lighting effect may include the following step S1101 and step S1102, as shown in fig. 11, in which:
In step S1101, color values of the respective divided blocks are calculated in combination with the illumination attenuation algorithm and the light source information. For example, the illumination attenuation algorithm may be calculating illumination, and the R value of the color channel may be obtained by calculating illumination (index data. R), where index data. R is the R value of the light source, and similarly, GBA values may be obtained in sequence, so as to obtain the color values of the divided blocks.
In step S1102, the divided blocks are rendered based on the color values to obtain lighting effects of the divided blocks. For example, pixel coloring may be performed on the object rendering GPU by using a Pixel loader, and a color value of each Pixel may be calculated in the Pixel loader and then the Pixel is colored, so as to determine an illumination effect of each partition block in the virtual scene. In addition, the virtual scene may be rendered by various rendering tools, for example, 3DMax, C4D, etc., which is not particularly limited in this embodiment.
In an exemplary embodiment, the method may include the following steps S1201 to S1206, as shown in fig. 12, in particular:
in step S1201, the virtual scene is divided to obtain divided blocks. In step S1202, a camera bounding box is calculated; taking the virtual reality application as an example, the camera bounding box is taken as a virtual scene in the current field of view, and the calculation method is shown in fig. 4. In step S1203, determining a light source in the current field of view and a partition block corresponding to the light source; and traversing all the light sources, determining whether an intersection exists between the light source range and the camera bounding box, and if so, determining that the partition blocks contained in the intersection correspond to the light sources. In step S1204, for each divided block, if the number of light sources corresponding to the divided block is greater than a preset value, the light sources are selected for deletion. In step S1205, texture information of the divided blocks is acquired. In step S1206, a lighting effect is calculated from the texture information. It should be understood that the steps shown in fig. 12 are correspondingly described in the above embodiments, and thus are not described herein.
In this embodiment, the illumination effect of the light source in the visual field range can be determined by segmenting the scene, and the light source outside the visual field range is removed, so that the computing resources can be reduced; and the problem of calculating the scene depth can be avoided, the cost of rendering the depth is reduced, and the problem of flicker of delay calculation is avoided. In addition, the process of determining the texture information can be performed on a CPU (Central processing Unit), an additional GPU (graphics processing Unit) channel is not needed, the requirement on hardware is low, the method can be applied to a mobile terminal, and the application range is wider.
