ATI Radeon® and SetTextureStageState() on DirectX®
8
The ATI Radeon® multitexture programming model has three
fully-orthogonal texture stages which are programmed as
a cascade. All three stages can introduce diffuse, specular,
constant and texture data.
Three Fully-Orthogonal Multitexture Units
- The following render states are valid as arguments to IDirect3DDevice8::SetTextureStageState() for all three texture stages:
- D3DTSS_COLORARG0, D3DTSS_COLORARG1 and D3DTSS_COLORARG2
- Color arguments 0, 1 and 2 can be set to any combinations of D3DTA_DIFFUSE, D3DTA_SPECULAR, D3DTA_TFACTOR, D3DTA_TEXTURE, D3DTA_CURRENT or D3DTA_TEMP.
- One or both of the D3DTA_ALPHAREPLICATE and D3DTA_COMPLEMENT modifier flags may be bitwise or'ed in to alpha-replicate and/or invert the argument.
- D3DTSS_COLOROP
- The valid color operations are:
- D3DTOP_DISABLE
- D3DTOP_SELECTARG1
- D3DTOP_SELECTARG2
- D3DTOP_MODULATE
- D3DTOP_MODULATE2X
- D3DTOP_MODULATE4X
- D3DTOP_ADD
- D3DTOP_ADDSIGNED
- D3DTOP_ADDSIGNED2X
- D3DTOP_SUBTRACT
- D3DTOP_BLENDDIFFUSEALPHA
- D3DTOP_BLENDTEXTUREALPHA
- D3DTOP_BLENDFACTORALPHA
- D3DTOP_BLENDTEXTUREALPHAPM
- D3DTOP_BLENDCURRENTALPHA
- D3DTOP_MODULATEALPHA_ADDCOLOR
- D3DTOP_MODULATEINVALPHA_ADDCOLOR
- D3DTOP_BUMPENVMAP
- D3DTOP_DOTPRODUCT3
- D3DTOP_MULTIPLYADD
- D3DTOP_LERP
- D3DTSS_ALPHAARG0, D3DTSS_ALPHAARG1 and D3DTSS_ALPHAARG2
- Alpha arguments 0, 1 and 2 can be set to any combinations of D3DTA_DIFFUSE, D3DTA_SPECULAR, D3DTA_TFACTOR, D3DTA_TEXTURE, D3DTA_CURRENT or D3DTA_TEMP.
- The D3DTA_COMPLEMENT modifier flag may be bitwise or'ed in to invert the argument.
- D3DTSS_ALPHAOP
- The valid alpha operations are:
- D3DTOP_DISABLE
- D3DTOP_SELECTARG1
- D3DTOP_SELECTARG2
- D3DTOP_MODULATE
- D3DTOP_MODULATE2X
- D3DTOP_MODULATE4X
- D3DTOP_ADD
- D3DTOP_ADDSIGNED
- D3DTOP_ADDSIGNED2X
- D3DTOP_SUBTRACT
- D3DTOP_MULTIPLYADD
- D3DTOP_LERP
- The D3DTSS_RESULTARG
- This state can be set to D3DTA_TEMP or D3DTA_CURRENT.
- The D3DTSS_BUMPENVMATxy
- These states can be set to floats in the range [-8.0 to 8.0)
- D3DTSS_TEXCOORDINDEX
- Any value 0..7
- D3DTSS_TCI_CAMERASPACENORMAL
- D3DTSS_TCI_CAMERASPACEPOSITION
- D3DTSS_TCI_CAMERASPACEREFLECTIONVECTOR
- D3DTSS_ADDRESSU, D3DTSS_ADDRESSV and D3DTSS_ADDRESSW
- Support for all five Direct3D® texture addressing modes:
- D3DTADDRESS_WRAP
- D3DTADDRESS_MIRROR
- D3DTADDRESS_MIRRORONCE
- D3DTADDRESS_CLAMP
- D3DTADDRESS_BORDER
- D3DTSS_BORDERCOLOR
- Color to be used for rasterizing texture coordinates outside the [0.0, 1.0] range.
- D3DTSS_MAGFILTER
- Support for the following magnification filter modes:
- D3DTFG_POINT
- D3DTFG_LINEAR
- D3DTFG_ANISOTROPIC
- D3DTSS_MINFILTER
- Support for the following minification filter modes:
- D3DTFN_POINT
- D3DTFN_LINEAR
- D3DTFN_ANISOTROPIC
- D3DTSS_MIPFILTER
- Support for the following mip-map filter modes:
- D3DTFP_NONE
- D3DTFP_POINT
- D3DTFP_LINEAR
- D3DTSS_MIPMAPLODBIAS
- Level of detail bias for mipmaps. Floating-point values in the range of -1.0 to 1.0 are meaningful
- D3DTSS_MAXMIPLEVEL
- Maximum mipmap level-of-detail that the application will allow, expressed as an index from the top of the mipmap chain.
- D3DTSS_MAXANISOTROPY
- Maximum degree of anisotropy for anisotropic filter kernel.
- D3DTSS_TEXTURETRANSFORMFLAGS
- D3DTTFF_DISABLE, D3DTTFF_COUNT1, D3DTTFF_COUNT2 or D3DTTFF_COUNT3. D3DTTFF_PROJECTED can be bitwise OR'ed in.
