Texture argument constants are used as values for the following members of the D3DTEXTURESTAGESTATETYPE enumerated type:
You can combine an argument flag with a modifier, but two argument flags cannot be combined.
|D3DTA_CONSTANT||Select a constant from a texture stage. The default value is 0xffffffff.|
|D3DTA_CURRENT||The texture argument is the result of the previous blending stage. In the first texture stage (stage 0), this argument is equivalent to D3DTA_DIFFUSE. If the previous blending stage uses a bump-map texture (the D3DTOP_BUMPENVMAP operation), the system chooses the texture from the stage before the bump-map texture. If s represents the current texture stage and s - 1 contains a bump-map texture, this argument becomes the result output by texture stage s - 2. Permissions are read/write.|
|D3DTA_DIFFUSE||The texture argument is the diffuse color interpolated from vertex components during Gouraud shading. If the vertex does not contain a diffuse color, the default color is 0xffffffff. Permissions are read-only.|
|D3DTA_SELECTMASK||Mask value for all arguments; not used when setting texture arguments.|
|D3DTA_SPECULAR||The texture argument is the specular color interpolated from vertex components during Gouraud shading. If the vertex does not contain a specular color, the default color is 0xffffffff. Permissions are read-only.|
|D3DTA_TEMP||The texture argument is a temporary register color for read or write. D3DTA_TEMP is supported if the D3DPMISCCAPS_TSSARGTEMP device capability is present. The default value for the register is (0.0, 0.0, 0.0, 0.0). Permissions are read/write.|
|D3DTA_TEXTURE||The texture argument is the texture color for this texture stage. Permissions are read-only.|
|D3DTA_TFACTOR||The texture argument is the texture factor set in a previous call to the SetRenderState with the D3DRS_TEXTUREFACTOR render-state value. Permissions are read-only.|
An argument flag may be combined with one of the following modifier flags.
|D3DTA_ALPHAREPLICATE||Replicate the alpha information to all color channels before the operation completes. This is a read modifier.|
|D3DTA_COMPLEMENT||Take the complement of the argument x, (1.0 - x). This is a read modifier.|
|Minimum operating system||Windows 98|
