| enum CC3Semantic |
Indicates the semantic usage for scene content.
Under OpenGL ES 2, these values are used to match an GLSL program variable to its semantic usage within a GLSL shader.
The semantic value kCC3SemanticAppBase and kCC3SemanticMax define a range of values that can be used by the application to define and match custom app-specific semantics. The framework will not automatically assign or use values within this range, so it can be used by the app to indicate an app-specific semantic usage.
