Defines how primvar are interpolated.

Possible Values

Value

Brief Explanation

RPR_PRIMVAR_INTERPOLATION_CONSTANT

0x1

This primvar set has a unique constant value for the whole shape.

RPR_PRIMVAR_INTERPOLATION_UNIFORM

0x2

Each face is mapped to a value. There is no interpolation between faces.

RPR_PRIMVAR_INTERPOLATION_VERTEX

0x3

Each vertex is mapped to a value. The primvar lookup uses vertice positions to interopolate each primvar value.

RPR_PRIMVAR_INTERPOLATION_FACEVARYING_NORMAL

0x4

Each vertex is mapped to a value. The primvar lookup uses vertice normals to interopolate each primvar value.

RPR_PRIMVAR_INTERPOLATION_FACEVARYING_UV

0x5

Each vertex is mapped to a value. The primvar lookup uses vertice UVs to interopolate each primvar value.
