sdlxCreateGpuComputePipeline function gpu

Pointer<SdlGpuComputePipeline> sdlxCreateGpuComputePipeline(Pointer<SdlGpuDevice> device, SdlxGpuComputePipelineCreateInfo createinfo)

Creates a pipeline object to be used in a compute workflow.

Shader resource bindings must be authored to follow a particular order depending on the shader format.

For SPIR-V shaders, use the following resource sets:

• 0: Sampled textures, followed by read-only storage textures, followed by read-only storage buffers
• 1: Read-write storage textures, followed by read-write storage buffers
• 2: Uniform buffers

For DXBC and DXIL shaders, use the following register order:

• (tn, space0): Sampled textures, followed by read-only storage textures, followed by read-only storage buffers
• (un, space1): Read-write storage textures, followed by read-write storage buffers
• (bn, space2): Uniform buffers

For MSL/metallib, use the following order:

• [buffer]: Uniform buffers, followed by read-only storage buffers, followed by read-write storage buffers
• [texture]: Sampled textures, followed by read-only storage textures, followed by read-write storage textures

There are optional properties that can be provided through props. These are the supported properties:

• SDL_PROP_GPU_COMPUTEPIPELINE_CREATE_NAME_STRING: a name that can be displayed in debugging tools.

\param device a GPU Context. \param createinfo a struct describing the state of the compute pipeline to create. \returns a compute pipeline object on success, or NULL on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.2.0.
