Using a compute shader as the front end of a vertex shader

Title:

Using a compute shader as the front end of a vertex shader

Document Type and Number:

Japanese Patent JP6309620

Kind Code:

B2

Abstract:

A computer graphics processing method, comprising processing a set of graphics primitive information for a virtual object with compute shader running on a GPU to generate a modified set of primitive information, passing the modified set of primitive information to a vertex shader running on the GPU by explicitly writing data corresponding to the modified set of primitive information with the compute shader running on the GPU, and performing vertex shading on the modified set of primitive information with the vertex shader, wherein the compute shader is configured to write through a GPU cache to a ring buffer and the vertex shader is configured to read through the GPU cache from the ring buffer, the data corresponding to the modified set of primitive information is written to the ring buffer and GPU cache by the compute shader, and the vertex shader accesses the modified set of primitive information.
