This command will set a vertex shader stream for the specified vertex shader. The stream index must start from one, being the first stream into the shader. The Data is specified using one of the following values, which relate to the FVF Format code you would use to convert your object prior to using a shader:VSDE_POSITION=FVF_XYZ=0, VSDE_BLENDWEIGHT=FVF_XYZRHW=1, VSDE_BLENDINDICES=FVF_XYZB1=2, VSDE_NORMAL=FVF_NORMAL=3, VSDE_PSIZE=FVF_PSIZE=4, VSDE_DIFFUSE=FVF_DIFFUSE=5, VSDE_SPECULAR=FVF_SPECULAR=6, VSDE_TEXCOORD0=FVF_TEX0=7, VSDE_TEXCOORD1=FVF_TEX0=8, VSDE_TEXCOORD2=FVF_TEX0=9, VSDE_TEXCOORD3=FVF_TEX0=10, VSDE_TEXCOORD4=FVF_TEX0=11, VSDE_TEXCOORD5=FVF_TEX0=12, VSDE_TEXCOORD6=FVF_TEX0=13, VSDE_TEXCOORD7=FVF_TEX0=14. The Datatype is specified using one of the following values:
