The DispatchIndirectWithAttributes method is used to execute a compute shader on the GPU using indirect dispatch parameters. This method allows you to specify additional rendering attributes that can be used during the dispatch process. It is particularly useful when you need to execute a compute shader with parameters that are determined at runtime and stored in a GPU buffer.
To use the DispatchIndirectWithAttributes method, you need to provide the following parameters:
attributes: An instance of RenderAttributes that contains additional rendering attributes to be used during the dispatch.indirectBuffer: A GpuBuffer that contains the dispatch parameters. This buffer should be populated with the appropriate data before calling this method.indirectElementOffset: A UInt32 value that specifies the offset in the indirectBuffer where the dispatch parameters are located.Ensure that the indirectBuffer is properly set up with the correct dispatch parameters before invoking this method.
// Example of using DispatchIndirectWithAttributes // Create and configure the RenderAttributes RenderAttributes attributes = new RenderAttributes(); // Configure attributes as needed // Create a GpuBuffer and populate it with dispatch parameters GpuBuffer indirectBuffer = new GpuBuffer(); // Populate indirectBuffer with appropriate data // Define the offset where the dispatch parameters are located uint indirectElementOffset = 0; // Create an instance of ComputeShader ComputeShader computeShader = new ComputeShader(); // Dispatch the compute shader with indirect parameters and attributes computeShader.DispatchIndirectWithAttributes(attributes, indirectBuffer, indirectElementOffset);
