[0002] Post-processing is a general term for full-screen image rendering effects, which can greatly improve the visual effect of a product. Post-processing occurs after a camera renders a scene but before the scene is rendered onto a screen.

[0003] At present, most game engines include a post-processing system, but some game engines, such as the Cocos2dx engine, do not. As the demand for picture improvement of game products is becoming higher and higher, it is extremely important for each game engine to implement a post-processing function. SUMMARY

[0005] The present application provides an image rendering method, device, storage medium and electronic equipment, which can implement a post-processing function in a game engine.

[0006] In response to a post-processing request for a target virtual camera in a game scene, a post-processing data group list corresponding to the target virtual camera is determined. The post-processing data group list includes at least one post-processing data group. Each post-processing data group includes rendering content of a corresponding post-processing operation, attribute data of the rendering content, and a renderer identifier.

[0007] According to the post-processing data group list, input frame buffers and output frame buffers corresponding to each post-processing operation are determined.

[0008] According to the renderer identifier, a target renderer plug-in used by the corresponding post-processing operation is determined.

[0009] According to the target renderer plug-in, the rendering content, and the input frame buffer, a rendering image corresponding to the corresponding post-processing operation is generated in the output frame buffer.

[0052] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0053] It should be noted that the terms "first," "second," etc., herein are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. In addition, the terms "include" and / or "comprise" as used herein specify the presence of stated features, integers, steps, operations, units, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, units, components, and / or combinations thereof.

[0054] Embodiments of the present application provide an image rendering method, apparatus, storage medium, and electronic device.

[0055] See Figure 1 , Figure 1 : This is a flow chart of an image rendering method provided in an embodiment of the present application. The image rendering method is applied to an electronic device such as a server or a terminal device, in which a game engine such as Cocos2dx can be installed. The specific process may include the following steps S101-S104, wherein:

[0056] S101. In response to a post-processing request for a target virtual camera in a game scene, a list of post-processing data groups corresponding to the target virtual camera is determined, the list of post-processing data groups including at least one post-processing data group, each post-processing data group including rendering content of a corresponding post-processing operation, attribute data of the rendering content, and a renderer identifier.

[0057] The game scene can be a three-dimensional model created by a game engine, and elements in the game scene include a virtual camera. The target virtual camera refers to a virtual camera that needs to be post-processed. The virtual camera is actually a simulation of the law of the human eye looking at an object, such as a small distance and a large distance. In the case of a virtual camera, the objects displayed in the game scene are affected by the position of the virtual camera. The virtual camera is equivalent to the human eye, and when looking at an object through the virtual camera, the shape of the object will be affected by the position and rotation angle of the camera. Generally, multiple virtual cameras can be set in the game scene, each virtual camera is provided with a flag (FLAG), and different virtual cameras are distinguished by the flag. Each object to be displayed also has a camera mask to determine which cameras the object is "seen" by.

[0058] The post-processing operation on the target virtual camera is essentially a further rendering operation on the image drawn by the camera, such as anti-aliasing, depth of field, color grading, motion blur, etc. Each post-processing data group corresponds to a post-processing operation, and the number of post-processing data groups can be determined according to actual needs. For example, when the final post-processing effect needs to be realized through multiple post-processing operations, multiple post-processing data groups can be included in the list of post-processing data groups. When the final post-processing effect can be realized through only one post-processing operation, only one post-processing data group can be included in the list of post-processing data groups.

[0059] The renderer identifier is mainly used to identify the renderer, which can be represented as an ID number. The rendering content mainly includes a frame buffer, each frame buffer corresponds to a frame image, and the frame buffer can include color buffer, depth buffer, and stencil buffer, i.e., color information, depth information, and stencil information, etc. Each post-processing operation can be regarded as a further rendering operation on the rendering image, which can be the drawing image of the camera itself or the rendering image after further rendering of the camera drawing image. The attribute data mainly indicates the category of the frame buffer area to which the frame buffer is written. The attribute data can include frame buffer size, number of color buffers, use of depth stencil, and stencil format, etc. Generally, the frame buffer obtained by the post-processing operation needs to be written to the frame buffer area of the corresponding category.

[0060] In some embodiments, a post-processing component (PostProcessVolume) can be built in the electronic device, and a user can design a post-processing effect on a virtual camera by invoking the post-processing component, i.e., please refer to Figure 2 Before step S101, the image rendering method can further include S1051 and S1052, wherein:

[0061] S1051. In response to a post-processing setting request for a target virtual camera in a game scene, display a post-processing operation setting interface corresponding to the target virtual camera in a graphical user interface, and provide a plurality of input interfaces on the post-processing operation setting interface, each input interface corresponding to a post-processing operation.

[0062] The post-processing operation setting interface can be a display interface providing various post-processing components, each input interface corresponding to a post-processing component, and a user can select a desired post-processing component through the input interface for addition and set a corresponding post-processing effect (post-processing data set). Each input interface can be associated with a parameter setting page, and a user can enter the corresponding parameter setting page through the input interface for parameter setting to obtain corresponding input information.

[0063] For example, please refer to Figure 3 , Figure 3 A post-processing operation setting interface corresponding to a target virtual camera is shown, and the post-processing operation setting interface can provide an input interface for setting an anti-aliasing effect, an input interface for setting an auto-exposure effect, an input interface for setting a motion blur effect, and an input interface for setting a depth-of-field effect, etc. A desired input interface can be selected to enter a corresponding parameter setting page for information input. Different input information of the same input interface can achieve different processing effects of the same type of post-processing operation, and input information in different input interfaces can achieve different types of post-processing operations.

[0064] In some embodiments, before setting a post-processing effect, a game scene needs to be constructed, i.e., before the above step "in response to a post-processing setting request for a target virtual camera in a game scene", the image rendering method further includes:

[0065] running a preset game engine;

[0066] constructing the game scene by running the preset game engine, and displaying the game scene in a graphical user interface.

[0067] The preset game engine can be a Cocos2dx engine, and the building of the game scene mainly refers to drawing and running a three-dimensional model corresponding to the game scene and elements in the three-dimensional model, such as a virtual camera. When the game scene is displayed on the graphical user interface, the user can select a virtual camera as a target virtual camera, and trigger the generation of a post-processing setting request for the target virtual camera through a specified function key on the graphical user interface, such as selecting the specified function key by clicking or other touch methods.

[0068] It should be noted that when building the game scene, each virtual camera is correspondingly provided with a frame buffer (which can be referred to as a camera frame buffer), and the display screen in the electronic device is also correspondingly provided with a frame buffer (which can be referred to as an off-screen frame buffer). These frame buffers are encapsulated in the game engine in advance, and the mapping relationship between the virtual camera and the frame buffer and between the display screen and the frame buffer needs to be set in advance, so that when the rendering operation process is performed subsequently, each virtual camera can write its own drawing image into its own frame buffer based on the mapping relationship, and the final rendering image displayed on the display screen is written into the off-screen frame buffer.

[0069] For example, please refer to Figure 4 , Figure 4 A frame diagram of a rendering process in an electronic device is shown, the electronic device can be built-in with a game engine, a renderer module and a post-processing module, and the game engine can encapsulate frame buffers. When the game engine is running, the screen resolution needs to be set, and one of the frame buffers is selected as an off-screen frame buffer. Then, the game scene is drawn by a main thread, and the game scene and the remaining frame buffers are initialized (cleared). Then, the game scene is run, and a frame buffer (camera frame buffer) corresponding to each virtual camera is set from the remaining frame buffers, and the scene background is initialized. Then, the game scene is rendered by the renderer module to display the game scene in the graphical user interface, wherein the renderer module can call a local renderer or a renderer plug-in to perform the rendering operation. Then, the post-processing module performs post-processing operation in the game scene. Finally, when all the post-processing operations are completed, the final rendering image (game picture) is written into the off-screen frame buffer, and then the rendering image is obtained from the off-screen frame buffer and displayed on the display screen to present to the user.

[0070] S1052. In response to the user input information in the input interface, at least one post-processing data set corresponding to the target virtual camera is generated.

[0071] The post-processing data set for this post-processing operation can be generated based on the user input information obtained from all input interfaces. Since different post-processing data sets usually have different processing sequences, when there are multiple post-processing data sets, they need to be sorted first, that is, the above step of "determining a post-processing data set list corresponding to the target virtual camera" can specifically include:

[0072] determining at least one post-processing data set corresponding to the target virtual camera, and a priority of each post-processing data set;

[0073] generating a post-processing data set list according to the priority and all post-processing data sets.

[0074] The priority of each post-processing data set, that is, the priority of the corresponding post-processing component, is usually set in advance. When the user selects a post-processing component for the target virtual camera and sets the corresponding post-processing data set, the priority of the post-processing component can be bound to the post-processing data set. Then, based on the binding relationship, the post-processing data sets can be sorted in order of priority from high to low to obtain the list.

[0075] S102. According to the post-processing data set list, determine the input frame buffer and the output frame buffer corresponding to each post-processing operation.

[0076] The input frame buffer and the output frame buffer are both one of the encapsulated frame buffers in the game engine, which can be some default set frame buffers, such as camera frame buffers corresponding to virtual cameras, off-screen frame buffers corresponding to display screens, or other frame buffers. Different post-processing operations usually need to use different frame buffers for image rendering of post-processing effects.

[0077] In some embodiments, to avoid setting a dedicated frame buffer for each post-processing operation, thereby causing waste of frame buffers and excessive consumption of memory, the encapsulated frame buffers can be managed by a management pool, so that various post-processing operations can be implemented based on a small number of frame buffers, thereby improving the utilization rate of frame buffers and avoiding excessive consumption of memory.

[0078] For example, please continue to refer to Figure 2 The above step S102 can specifically include:

[0079] S1021. Traverse the attribute data in the post-processing data list;

[0080] S1022. In the traversal process, the input frame buffer and the output frame buffer corresponding to the post-processing operation are determined according to the attribute data obtained in each traversal operation, the traversal order and the stored frame buffer management pool, and the frame buffer management pool includes at least one first frame buffer that is not occupied.

[0081] In the context structure, the source is used to record the input frame buffer, and the destination is used to record the output frame buffer. In addition to the default frame buffers (such as the camera frame buffer and the off-screen frame buffer), other frame buffers encapsulated in the game engine and not occupied can be managed by the frame buffer management pool.

[0082] When there are multiple post-processing operations, a post-processing data group is obtained from the post-processing data list one by one to perform the corresponding post-processing operation, and the list arrangement order of each post-processing data group is the execution order of the corresponding post-processing operation. Since each post-processing operation is a further rendering operation on the rendered image, it is necessary to determine the rendered image that needs to be further rendered, and the rendered image is usually the content stored in the input frame buffer. At the same time, it is necessary to determine which frame buffer (i.e., the output frame buffer) the rendering result needs to be written to after further rendering.

[0083] In some embodiments, the step of "determining the input frame buffer and the output frame buffer corresponding to the post-processing operation according to the attribute data obtained in each traversal operation, the traversal order and the stored frame buffer management pool" specifically includes:

[0084] If the current traversal operation is the first traversal, a preset frame buffer corresponding to the target virtual camera is obtained as the input frame buffer corresponding to the current post-processing operation, and the output frame buffer corresponding to the current post-processing operation is determined according to the attribute data obtained in the current traversal operation and the stored frame buffer management pool.

[0085] If the current traversal operation is the intermediate traversal, the output frame buffer corresponding to the previous post-processing operation is taken as the input frame buffer of the current post-processing operation, and the output frame buffer corresponding to the current post-processing operation is determined according to the attribute data obtained in the current traversal operation and the frame buffer management pool.

[0086] If the current traversal operation is the last traversal, the output frame buffer corresponding to the previous post-processing operation is taken as the input frame buffer of the current post-processing operation, and the off-screen frame buffer is taken as the output frame buffer corresponding to the current post-processing operation.

[0087] The content in the input frame buffer is usually taken as the input content of the corresponding post-processing operation, and the output frame buffer is usually taken as the storage area of the rendering result after the corresponding post-processing operation is completed. Specifically, if the current post-processing operation is the first post-processing operation, the source of the context structure is set as the pointer of the camera frame buffer of the target virtual camera, indicating that the initial input content (source image) is obtained from the camera frame buffer; if the current post-processing operation is the last post-processing operation, the destination of the context structure is set as the pointer of the off-screen frame buffer, indicating that the rendering result needs to be written into the off-screen frame buffer; in other cases, the source is set as the destination, indicating that the input content of the current post-processing operation is the rendering result (i.e., the output of the previous post-processing operation) of the previous post-processing operation, and the destination is set as null, indicating that the rendering result needs to be written into a frame buffer in the frame buffer management pool.

[0088] In some embodiments, the step of "determining the output frame buffer corresponding to the current post-processing operation according to the attribute data obtained by the current traversal operation and the stored frame buffer management pool" can specifically include:

[0089] determining whether there is preset attribute data matching the attribute data obtained by the current traversal operation in a first dictionary, the first dictionary storing a plurality of preset attribute data and a pointer list corresponding to each preset attribute data, each pointer in the pointer list indicating a first frame buffer in the frame buffer management pool;

[0090] if there is, determining a target pointer from the pointer list corresponding to the matching preset attribute data, and taking the first frame buffer corresponding to the target pointer as the output frame buffer corresponding to the current post-processing operation;

[0091] if there is not, creating a frame buffer according to the attribute data as the output frame buffer corresponding to the current post-processing operation, and updating the frame buffer management pool and the first dictionary according to the created frame buffer.

[0092] The management of the unoccupied frame buffer in the frame buffer management pool can be completed by a first dictionary, which is constantly updated and maintained. The first dictionary composed of keys and values can be constructed by taking preset attribute data as the key and taking a pointer list as the value. The preset attribute data can be created in advance according to the situation of all frame buffers encapsulated in the game engine, and each preset attribute data represents a type of frame buffer. Each type can correspond to multiple or one unoccupied frame buffer, and any one of them can be selected as the output frame buffer corresponding to the current post-processing operation. If there is no matching unoccupied frame buffer in the frame buffer management pool, a new frame buffer can be created as the output frame buffer according to the attribute data, and the newly created frame buffer is added to the frame buffer management pool as the first frame buffer, and the newly created frame buffer and the corresponding attribute data are stored in the first dictionary for association, so as to update the frame buffer management pool and the first dictionary.

[0093] In addition, the frame buffer management pool can manage not only the unoccupied frame buffer but also the occupied frame buffer, that is, the frame buffer management pool can also include at least one occupied second frame buffer. At this time, the image rendering method further includes:

[0094] releasing the second frame buffer in response to a release request for the second frame buffer;

[0095] updating a stored second dictionary according to the identification information of the released second frame buffer, the second dictionary storing a plurality of preset identification information and a pointer corresponding to the preset identification information, each pointer indicating a second frame buffer in the frame buffer management pool;

[0096] updating the first dictionary according to the attribute data of the released second frame buffer.

[0097] The release of the second frame buffer can include clearing the content written in the second frame buffer. The identification information can be an ID code, and all frame buffers in the game engine have their own ID code. The second dictionary composed of keys and values can be constructed by taking the identification information as the key and taking the pointer as the value, and the occupied frame buffer in the frame buffer management pool is managed by the second dictionary. Once a second frame buffer in the frame buffer management pool is released, it needs to be removed from the second dictionary and added to the first dictionary.

[0098] S103. Determine the target renderer plug-in used by the corresponding post-processing operation according to the renderer identifier.

[0099] In some embodiments, a local renderer can be installed in the electronic device, and a plurality of renderer plugins, such as a sunshafts effect renderer plugin, a bloom effect renderer plugin, and the like, can also be installed. Each renderer plugin can be provided with a unique renderer identifier, by which a target renderer plugin is determined from the plurality of renderer plugins. The renderer plugin and the game engine have different implementation ends, such as the game engine can be implemented at a C++ end, and the renderer plugin can be implemented at a lua end, that is, the implementation of the render function and the start function of the renderer module in the above Figure 4 start function is mainly used to perform initialization operations before rendering, and the render function is mainly used to perform rendering operations.

[0100] S104. According to the target renderer plugin, the rendering content, and the input frame buffer, a rendering image corresponding to the post-processing operation is generated in the output frame buffer.

[0101] Once all post-processing operations are completed, that is, the rendering image of the current processing operation is written into the off-screen frame buffer, it can be obtained from the off-screen frame buffer and displayed in the graphical user interface. In each execution of the post-processing operation, once the context structure is set, the renderer identifier corresponding renderer plugin can be called to work, which involves accessing the context structure in the game engine (C++ end) and the frame buffer management pool. The called renderer plugin can access the input frame buffer corresponding to the post-processing operation in the game engine (which can be regarded as accessing the frame buffer management pool) by accessing the set context structure, and further access the output frame buffer corresponding to the post-processing operation (which can be regarded as accessing the frame buffer management pool) by accessing the set context structure, and further render the object in the output frame buffer. That is, the above step S104 can specifically include: calling the target renderer plugin to draw the rendering content and the stored content in the input frame buffer in the output frame buffer to generate a rendering image corresponding to the post-processing operation.

[0102] It should be noted that, to realize the access of the renderer plug-in to the context structure and the frame buffer management pool, the context structure and the frame buffer management pool in the C++ end of the game engine need to be bound in the lua end; to realize the calling of the renderer plug-in based on the renderer identifier, the renderer plug-in with the same name as the renderer identifier needs to be set in the lua end. When the render function of the renderer module in the electronic device is executed, the renderer plug-in is called to realize it. When the post-processing rendering operation is performed in this binding mode, the implementation of each post-processing effect is responsible for the script, and the long time is not needed from the production to the presentation to the user, and the hot update is realized.

[0103] It should be noted that, in the execution process of the plurality of post-processing operations, when any post-processing operation is executed, the content in the output frame buffer of the previous post-processing operation is taken as the input content of the current processing operation, and then the output frame buffer can be released and the first dictionary and the second dictionary are updated. Once the content is written in the output frame buffer, that is, the single post-processing operation is completed, it indicates that the output frame buffer is occupied, and the first dictionary and the second dictionary need to be updated.

[0104] In addition, the above steps S101-S104 are only for the post-processing operation of a single target virtual camera, if the virtual cameras that need to be post-processed are multiple, the post-processing operation of each virtual camera can be sequentially executed in sequence.
