These macros define texture argument flags. Each texture stage for a device can have two texture arguments that affect the color or alpha channel of the texture.
Set and retrieve texture arguments by calling the IDirect3DMobileDevice::SetTextureStageState and IDirect3DMobileDevice::GetTextureStageState methods, and specifying the one of the following elements of the D3DMTEXTURESTAGESTATETYPE enumeration.
- D3DMTSS_COLORARG0
- D3DTMSS_COLORARG1
- D3DMTSS_COLORARG2
- D3DMTSS_ALPHAARG0
- D3DTSS_ALPHAARG1
- D3DTSS_ALPHAARG2
- D3DTSS_RESULTARG
The following table shows flags, organized as arguments and modifiers, that can be used with color and alpha arguments for a texture stage. You can combine an argument flag with a modifier, but two argument flags cannot be combined.
| Value | Description |
|---|---|
| D3DMTA_SELECTMASK | Mask value for all arguments; not used when setting texture arguments. |
| D3DMTA_DIFFUSE | Attaches the pixel's diffuse color to the texture stage input.
This is a read-only operation. |
| D3DMTA_CURRENT | Attaches the current color register to the texture stage input.
This is a read/write operation. |
| D3DMTA_TEXTURE | Attaches the color value read from the stage's texture map at the pixel's coordinates to the texture stage input.
This is a read-only operation. |
| D3DMTA_TFACTOR | Attaches the texture factor color value to the stage's input. The texture factor is a render state, D3DMRS_TEXTUREFACTOR, that accepts a 32-bit ARGB color value (see D3DMRENDERSTATETYPE)).
This is a read-only operation. |
| D3DMTA_SPECULAR | Attaches the pixel's specular color to the texture stage input.
This is a read-only operation. |
| D3DMTA_TEMP | Attaches the temporary color register to the texture stage input.
This is a read/write operation. |
| D3DMTA_OPTIONMASK | Mask value for option bits. |
| D3DMTA_COMPLEMENT | Takes 1.0 – x for each color channel and use that as the input.
This flag is used to specify a preprocessing operation. It only affects the input to the texture stage, not the original color value used as the input. This is a read-modifying operation. |
| D3DMTA_ALPHAREPLICATE | Replicates the value in the alpha channel to all color components for the stage input.
This flag is used to specify a preprocessing operation. It only affects the input to the texture stage, not the original color value used as the input. This is a read-modifying operation. |
| D3DMTA_VALIDMASK | D3DMTA_OPTIONMASK | D3DMTA_SELECTMASK |
