DX9中的Vertex Shader中的input

BINORMAL[n]	Binormal	float4
BLENDINDICES[n]	Blend indices	uint
BLENDWEIGHT[n]	Blend weights	float
COLOR[n]	Diffuse and specular color	float4
NORMAL[n]	Normal vector	float4
POSITION[n]	Vertex position in object space.	float4
POSITIONT	Transformed vertex position.	float4
PSIZE[n]	Point size	float
TANGENT[n]	Tangent	float4
TEXCOORD[n]	Texture coordinates	float4

DX9中Vertex Shader中的output

COLOR[n]	Diffuse or specular color	float4
FOG	Vertex fog	float
POSITION[n]	Position of a vertex in homogenous space. Compute position in screen-space by dividing (x,y,z) by w. Every vertex shader must write out a parameter with this semantic.	float4
PSIZE	Point size	float
TESSFACTOR[n]	Tessellation factor	float
TEXCOORD[n]	Texture coordinates	float4

DX9中的像素着色器的input

COLOR[n]	Diffuse or specular color.	float4
TEXCOORD[n]	Texture coordinates	float4
VFACE	Floating-point scalar that indicates a back-facing primitive. A negative value faces backwards, while a positive value faces the camera.	float
VPOS	The pixel location (x,y) in screen space. To convert a Direct3D 9 shader (that uses this semantic) to a Direct3D 10 shader, see Direct3D 9 VPOS and Direct3D 10 SV_Position)	float2

DX9中像素着色器的output

COLOR[n]	Output color	float4
DEPTH[n]	Output depth	float
