class ShaderGenerator

Detailed Description

Class containing all data needed during shader generation.

After generation is completed it will contain the resulting source code emitted by shader generators.

The class contains a default implementation using a single shader stage. Derived shaders can override this, as well as overriding all methods that add code to the shader.

The documentation for this class was generated from the following files:
