WebGPU Shader

This chapter mainly introduces how to use the wgsl language to write orillusion shader code and considerations.

Similar to mainstream 3D engines, theMeshRender in the orillusion rendering module can have multiple materials, and each material can define multiple rendering channels. During a rendering task, the engine outputs different results according to the rules based on the material type, rendering channel type, and priority.

Shader Classification

In Orillusion , shader can be divided into two categories, each with a different purpose and usage:

• RenderShader - shader program used for vertex shading and fragment shading stages
• ComputeShader - shader program used for general-purpose computing on the GPU outside of the conventional graphics pipeline
