Constants

D3DPTEXTURECAPS_PERSPECTIVE

Perspective correction texturing is supported.

D3DPTEXTURECAPS_POW2

All textures must have widths and heights specified as powers of 2. This requirement does not apply to either cube textures or volume textures.

D3DPTEXTURECAPS_ALPHA

Alpha in texture pixels is supported.

D3DPTEXTURECAPS_SQUAREONLY

All textures must be square.

D3DPTEXTURECAPS_TEXREPEATNOTSCALEDBYSIZE

Texture indices are not scaled by the texture size prior to interpolation.

D3DPTEXTURECAPS_ALPHAPALETTE

Device can draw alpha from texture palettes.

D3DPTEXTURECAPS_NONPOW2CONDITIONAL

Conditionally supports the use of textures with dimensions that are not powers of 2. A device that exposes this capability can use such a texture if all of the following requirements are met.

• The texture addressing mode for the texture stage is set to D3DTADDRESS_CLAMP.
• Texture wrapping for the texture stage is disabled (D3DRS_WRAPn set to 0).
• Mipmapping is not in use (use magnification filter only).

D3DPTEXTURECAPS_PROJECTED

Supports the D3DTTFF_PROJECTED texture transformation flag. When applied, the device divides transformed texture coordinates by the last texture coordinate. If this capability is supported then the projective divide happens on a per pixel basis. If this capability is not set and the application still wants the projective divide to happen, then it happens on a per-vertex basis by the Direct3D runtime.

D3DPTEXTURECAPS_CUBEMAP

Supports cube textures.

D3DPTEXTURECAPS_VOLUMEMAP

Device supports volume textures.

D3DPTEXTURECAPS_MIPMAP

Device supports mipmapped textures.

D3DPTEXTURECAPS_MIPVOLUMEMAP

Device supports mipmapped volume textures.

D3DPTEXTURECAPS_MIPCUBEMAP

Device supports mipmapped cube textures.

D3DPTEXTURECAPS_CUBEMAP_POW2

Device requires that cube texture maps have dimensions specified as powers of 2.

D3DPTEXTURECAPS_VOLUMEMAP_POW2

Device requires that volume texture maps have dimensions specified as powers of 2.

Remarks

These flags may be combined and present in the TextureCaps member of D3DCAPS8.
