TECHNIQUES FOR SETTING UP AND EXECUTING DRAW CALLS

摘要

One embodiment sets forth a method for processing draw calls that includes setting up a plurality of shader input buffers in memory, receiving shader input data related to a graphics scene from a software application, storing the shader input data in the plurality of shader input buffers, computing a pointer to each shader input buffer included in the plurality of shader input buffers, and passing the pointers to the plurality of shader input buffers to the software application. By implementing the disclosed techniques, a shader program advantageously can access the shader input data associated with a graphics scene and stored in various shader input buffers without having to go through the central processing unit to have the shader input buffers binded to the shader program.
