Input semantics

The binding semantics in the following table can be used in vertInput, which is the structure that Unity provides to the vertex function. The fields decorated with this semantics will be initialized automatically:

Binding semantics	Description
POSITION, SV_POSITION	The position of a vertex in world coordinates (object space)
NORMAL	The normal of a vertex, relative to the world (not to the camera)
COLOR, COLOR0, DIFFUSE, SV_TARGET	The color information stored in the vertex
COLOR1, SPECULAR	The secondary color information stored in the vertex (usually the specular)
TEXCOORD0, TEXCOORD1, …, TEXCOORDi	The i-th UV data stored in the vertex
