[0002] In three-dimensional scene drawing, surface subdivision is an effective method to express the surface details of an object. This method automatically generates a large number of new vertices on the surface of the object, which will make the model surface either smooth and delicate (such as the face) or rugged (such as the terrain and the sea surface). It has been widely used on mainstream drawing platforms such as D3D, OpenGL, and Vulkan.

[0003] In the related art, there is only one execution mode for surface subdivision. Regardless of whether the control points output by the shell shader come from the output points of the vertex shader, the shell shader must execute the loading instructions of the input data and the output instructions of the control point data; and regardless of whether the image subdivision parameters output by the shell shader are constants, the shell shader must execute the output instructions of the image subdivision parameters.

[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] In related technologies, before the tessellation module is introduced into the graphics pipeline, the geometry shader GS (Geometry Shader) is generally used to generate geometric detail information. GS is an important shader of D3D10.0, which can generate new vertices by writing a shading program, but it is a general module, and the generated algorithm is too complex, the execution time is long, and it is not conducive to real-time rendering.

[0031] To improve the realism of the drawing and the smoothness of the picture, Figure 1 As shown in the figure, in addition to the traditional vertex shader (VS) and pixel shader (PS), the important function of surface subdivision has been added, with two new shaders, the hull shader (HS), the domain shader (DS) and a tessellation unit (TS). This subdivision module uses HS and DS to complete the pre-processing and post-processing calculations of TS, and the real-time drawing effect is also good.

[0032] Optionally, the shell shader HS is a pre-processing calculation of the TS, generating multiple image control point information (CPs, Control Points) and image subdivision parameters (PCs, Patch Consts) for the TS.

[0033] Exemplarily, HS obtains vertex information from VS, generates image control points (CPs) based on the vertex information, generates image subdivision parameters (PCs) based on the set image subdivision parameter configuration information, and sends the image control point information and image subdivision parameters to TS, which generates domain vertex information based on the image control point information and image subdivision parameters, and then sends the domain vertex information and the image control point information obtained from HS to DS, which performs the next step of data processing.

[0034] In one embodiment, VS includes a VSC (vertex shader control unit), HS includes an HSC (hull shader control unit), and DS includes a DSC (regional shader control unit), and VSC, HSC, and DSC perform corresponding functions. Exemplarily, VSC implements the output of vertex information, forms vertex thread bundles, and other steps. Exemplarily, HSC implements the steps of obtaining vertex information from VS, processing the vertex information to obtain image control point information, sending the image control point information to TESS, obtaining image subdivision parameters, and sending them to TESS, forming shell thread bundles, and other steps. Exemplarily, DSC implements the operations of applying for a regional cache area with the domain vertex information obtained from TESS, forming a regional thread bundle, and so on.

[0035] Optionally, a data buffer is also included for storing data output by VS, HS, and DS, for example, storing vertex information output by VS.

[0036] In actual application scenarios, HS may simply output the vertex information of VS (vertex shader) as control points (CPs) directly without any modification. Similarly, subdivision parameters (PCs) may also be a fixed constant, and HS does not need to calculate to obtain image subdivision parameters.

[0037] In the related art, when processing the surface subdivision module, there is only a single execution mode, that is, regardless of whether the HS directly outputs the vertex information output by the VS as CPs, and regardless of whether the PCs are constants, it is necessary to process based on the vertex information of the VS, perform calculations based on the image parameter configuration information, and generate storage intervals for the calculation results. Therefore, this single execution mode in the related art increases the input and output instructions corresponding to the HS, and also increases unnecessary storage space, resulting in low output processing efficiency.

[0038] To solve the above problems, Figure 2 As shown, an image data processing method is provided. This embodiment takes the method applied to a server as an example for illustration. It can be understood that the method can also be applied to a terminal, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0039] Step S202, obtaining the output mode corresponding to the hull shader transmitted by the vertex shader.

[0040] In one embodiment, the terminal and / or the server may be configured with a GPU (graphics processing unit), and the GPU is used to process the image data.

[0041] Optionally, a tessellation switch module may be provided to turn on or off tessellation.

[0042] In one embodiment, the GPU may receive input image data to be processed through a vertex shader, and perform a first step of processing on the image data to be processed through the vertex shader to obtain vertex information. Optionally, the vertex information includes but is not limited to position information, brightness information, etc.

[0043] In one embodiment, after generating vertex information, the vertex shader may generate a vertex warp and send the vertex warp to a warp processing unit, which performs processing according to the warp, for example, executing an instruction to input the vertex information into a vertex buffer.

[0044] In one embodiment, the vertex shader may also transmit an output mode corresponding to the shell shader and / or a control command corresponding to the shell shader.

[0045] Optionally, the output mode can be pre-configured, and the vertex shader transmits the output mode to the hull shader. Exemplarily, the output mode is configured by a software driver, and the vertex shader transmits the output mode configured by the software driver to the hull shader.

[0046] Optionally, the control instruction corresponding to the shell shader may include but is not limited to clearing the work task of the shell shader, etc.

[0047] In an optional embodiment, the vertex shader may obtain a vertex buffer for storing vertex information, and may generate a vertex warp from the vertex buffer and the vertex information. Optionally, after receiving the vertex warp information, the warp processing unit may perform corresponding processing based on the vertex warp, for example, inputting the vertex information into the vertex buffer, or obtaining the vertex information from the vertex buffer and further inputting it into the shell shader.

[0048] In one embodiment, when the vertex shader outputs information, it may also output the patch block size, so that the hull shader can compose the vertex information into patch blocks of a required size according to the received patch block size.

[0049] The output mode is used to indicate the type of image subdivision parameters and the output method of the shell shader for the first image control point information.

[0050] The image subdivision parameters are used to determine domain vertex information generated by the surface subdivision unit. Optionally, the domain vertex information includes but is not limited to the number of domain vertices and position information corresponding to the domain vertices.

[0051] In one embodiment, the image subdivision parameter may be a constant or may not be a constant.

[0052] Optionally, when the image subdivision parameter is a constant, the shell shader does not process the image subdivision parameter, and the surface subdivision unit directly obtains the image subdivision parameter from the image subdivision parameter register and generates domain vertex information based on the image subdivision parameter. Optionally, the image subdivision parameter configuration information can be pre-configured by software.

[0053] Optionally, when the image subdivision parameter is not a constant, the shell shader needs to perform processing to obtain the image subdivision parameter. Exemplarily, the shell shader obtains the image subdivision parameter configuration information transmitted by the vertex shader, and calculates based on the image subdivision configuration information to obtain the image subdivision parameter. Optionally, the image subdivision parameter configuration information can be pre-configured by software.

[0054] In one embodiment, the output mode of the image control point information of the hull shader can be determined according to the configuration information transmitted by the vertex shader. For example, if the configuration information transmitted by the vertex shader indicates that the image control point information is the vertex information output by the vertex shader, the hull shader directly sends the vertex information output by the vertex shader obtained as the image control point information to the tessellation unit. Alternatively, if the configuration information output by the vertex shader indicates that the image control point information is not the vertex information output by the vertex shader, the hull shader calculates the image control point information according to the vertex information output by the vertex shader, and sends the image control point information to the tessellation unit.

[0055] It can be understood that the execution method of the shell shader is different for different image subdivision parameters and / or different image control point information. Different output modes can be formed according to the differences in image subdivision parameters and image control point information, so as to obtain corresponding target processing logic according to different output modes, and the GPU can implement processing according to the target processing logic.

[0056] Optionally, the output mode includes at least one of a first output mode, a second output mode and a third output mode.

[0057] The first output mode indicates that the image control point information is vertex information output by the vertex shader, and the type of the image subdivision parameter is a constant.

[0058] The second output mode indicates that the image control point information is vertex information output by the vertex shader, and the type of the image subdivision parameter is a non-constant.

[0059] The third output mode indicates that the image control point information is not vertex information output by the vertex shader, and the type of the image subdivision parameter is a constant.

[0060] In an optional embodiment, the output mode may further include a fourth output mode, wherein the fourth output mode indicates that the image control point information is not vertex information output by the vertex shader, and the type of the image subdivision parameter is not a constant.

[0061] Step S204, obtaining the target processing logic according to the output mode.

[0062] The processing logic is used to indicate the processing steps of each component, for example, indicating the processing steps of the shell shader, the processing steps of the surface subdivision unit, the processing steps of the region shader, etc.

[0064] Exemplarily, the first output mode corresponds to the first processing logic, the second output mode corresponds to the second processing logic, the third output mode corresponds to the third processing logic, and the fourth output mode corresponds to the fourth processing logic.

[0065] Optionally, the first processing logic, the second processing logic, the third processing logic and the fourth processing logic are different from each other.

[0066] In one embodiment, after obtaining the output mode transmitted by the vertex shader, it is determined whether the output mode is the first output mode, the second output mode, the third output mode or the fourth output mode, and a matching process is performed based on the result of determining the output mode to obtain the processing logic corresponding to the output mode. Exemplarily, when the output mode is the first output mode, the corresponding processing logic is the first processing logic, and the first processing logic is the target processing logic.

The region shader obtains first region cache information for storing the first domain vertex information, and generates a first region thread bundle with the first region cache information, the first domain vertex information and the image control point information constituting the first patch block. Optionally, after generating the first region thread bundle, the region shader may send the generated first region thread bundle to the thread bundle execution module, and the thread bundle execution module executes based on the first region thread bundle.

The tessellation unit reads the image subdivision parameters from the first shell buffer, generates the second domain vertex information according to the image subdivision parameters and the image control point information constituting the first patch block, and sends the second domain vertex information and the image control point information constituting the first patch block to the region shader. The region shader obtains the second region buffer information for storing the second domain vertex information, and generates the second region warp by combining the second region buffer information, the image control point information constituting the first patch block and the second domain vertex information.

The region shader obtains the third region buffer information for storing the third domain vertex information, and composes the third region buffer information, the image control point information constituting the second patch block, and the third domain vertex into a third region warp.

[0071] In one embodiment, the third processing logic may further include: the shell shader obtains the second shell buffer information for storing the image control point information, sends the second shell buffer information to the surface, generates the second shell thread bundle according to the second shell buffer information and the image control point information, and sends the second shell thread bundle to the thread bundle processing unit.

The region shader obtains fourth region buffer information for storing fourth domain vertex information, and generates fourth region thread warps according to the fourth region buffer information, the fourth domain vertex information, and the image control point information constituting the third patch block. Optionally, the regional shader may send the fourth regional warp to the warp execution unit, and the warp execution unit may perform processing steps based on the warp execution. Exemplarily, the warp execution unit may perform the step of inputting vertex information and image subdivision parameters constituting the third patch block into the third shell buffer information based on the third shell warp execution. Exemplarily, the warp execution unit may also perform the step of inputting the fourth domain vertex information into the fourth regional buffer information based on the fourth regional warp execution.

[0074] Step S206: Process the image subdivision parameters and the image control point information according to the target processing logic to obtain a processing result.

[0075] In one embodiment, when the image control point information is vertex information output by a vertex shader, the vertex information output by the vertex shader can be directly output to the tessellation unit through a hull shader.

Exemplarily, if the image control point information is the vertex information of the shell shader, it can be considered that the output method of the image control point information indicated by the output mode is that the shell shader does not perform calculation processing on the vertex information output by the vertex shader, and the vertex information output by the vertex shader can be directly output to the surface subdivision unit as the image control point information. If, on the other hand, the image control point information is not the vertex information of the shell shader, it can be considered that the output method of the image control point information indicated by the output mode is that the shell shader needs to perform calculation processing on the vertex information output by the vertex shader, and can only output it after obtaining the image control point information.

If the image subdivision parameter is not a fixed constant, it can be considered that the type of the image subdivision parameter indicated by the output mode is not a constant type, the shell shader needs to calculate to obtain the image subdivision parameter, and the surface subdivision unit performs the step of generating domain vertex information based on the image subdivision parameter calculated by the shell shader.

[0079] In one of the embodiments, after obtaining the output mode corresponding to the shell shader transmitted by the vertex shader, the output mode can be matched with a preset output mode. For example, the output mode is matched with the first output mode, the second output mode, the third output mode and / or the fourth output mode to determine whether the output mode corresponding to the shell shader matches the first output mode, the second output mode, the third output mode or the fourth output mode. After matching, the corresponding target processing logic is determined, and the processing steps are executed based on the target processing logic.

[0080] Optionally, when the output mode is the first output mode, a first patch block is generated according to the image control point information by the shell shader, and the image control point information constituting the first patch block is sent to the surface subdivision unit, wherein the image control point information constituting the first patch block is the vertex information output by the vertex shader.

[0085] In one embodiment, when the output mode is the fourth output mode, it may also include obtaining, through a shell shader, a third shell buffer information for storing image control point information and image subdivision parameters constituting a third patch block, generating a third shell thread bundle based on the image control point information, the image subdivision parameters and the third shell buffer information, and sending the third shell buffer information to a tessellation unit; the tessellation unit obtains the image control point information and the image subdivision parameters based on the third shell buffer information. Optionally, the region shader may send the fourth region thread bundle to a thread bundle execution unit, and the thread bundle execution unit executes the processing steps based on the thread bundle. Exemplarily, the thread bundle execution unit executes the step of inputting the vertex information and image subdivision parameters constituting the third patch block into the third shell buffer information based on the third shell thread bundle. Exemplarily, the thread bundle execution unit may also execute the step of inputting the fourth domain vertex information into the fourth region buffer information based on the fourth region thread bundle.

Moreover, when the output mode indicates that the image control point information is the vertex information output by the shell shader, and the image subdivision parameter is a constant, the shell shader directly outputs the vertex information, and the surface subdivision unit directly obtains the image subdivision parameter. In this process, the shell shader does not need to generate a shell thread bundle, reducing the execution of application instructions, and does not need to allocate a shell buffer area for the shell shader, reducing the occupation of the storage space by the shell shader, then the vertex shader and the region shader can obtain more storage space, and more vertex thread bundles and region thread bundles can be started in parallel, effectively improving the data processing efficiency. In the above-mentioned image processing method, when there is image control point information that is not vertex information output by the vertex shader and the image subdivision parameter is a constant, or when the image control point information is vertex information output by the vertex shader and the image subdivision parameter is not a constant, although the shell shader needs to generate a shell thread bundle and needs to allocate storage space for the image control point information or the image subdivision parameter, it only executes the calculation steps of the image control point information or the image subdivision parameter, and allocates storage space for the image control point information or the image subdivision parameter. Compared with the related art of calculating and processing the image control point information and the image subdivision parameter and allocating storage space, it can effectively reduce the calculation steps and save storage space. It can also obtain more storage space for the vertex shader and the region shader, and can start more vertex thread bundles and region thread bundles in parallel, effectively improving data processing efficiency.

Moreover, when the output mode indicates that the image control point information is the vertex information output by the shell shader, and the image subdivision parameter is a constant, the shell shader directly outputs the vertex information, and the surface subdivision unit directly obtains the image subdivision parameter. In this process, the shell shader does not need to generate a shell thread bundle, reducing the execution of application instructions, and does not need to allocate a shell buffer area for the shell shader, reducing the occupation of the storage space by the shell shader, then the vertex shader and the region shader can obtain more storage space, and more vertex thread bundles and region thread bundles can be started in parallel, effectively improving the data processing efficiency. In the above-mentioned image processing method, when there is image control point information that is not vertex information output by the vertex shader and the image subdivision parameter is a constant, or when the image control point information is vertex information output by the vertex shader and the image subdivision parameter is not a constant, although the shell shader needs to generate a shell thread bundle and needs to allocate storage space for the image control point information or the image subdivision parameter, it only executes the calculation steps of the image control point information or the image subdivision parameter, and allocates storage space for the image control point information or the image subdivision parameter. Compared with the related art of calculating and processing the image control point information and the image subdivision parameter and allocating storage space, it can effectively reduce the calculation steps and save storage space.
