These are shader and effect constants.
| #define | Description |
|---|---|
| D3DX_PARAMETER_SHARED | The value of a parameter will be shared by all effects in the same namespace. Changing the value in one effect will change it in all shared effects. See Sharing Parameters. |
| D3DX_PARAMETER_LITERAL | This parameter is marked as a literal value. Literal parameters cannot change after compile, allowing the compiler to optimize their usage. Shared parameters cannot be marked as a literal. See Usages and Literals. |
| D3DX_PARAMETER_ANNOTATION | This parameter is marked as an annotation. See Annotations. |
D3DX_PARAMETER_SHARED cannot be combined with LITERAL or ANNOTATION.
Effect parameter constants are used by D3DXPARAMETER_DESC.
Effects use handles to reference techniques, passes, annotations, and parameters.
