General texture filtering flags

D3DPTFILTERCAPS_LINEAR

Bilinear filtering. Chooses the texel that has nearest coordinates, then performs a weighted average with the four surrounding texels to determine the final color. This applies to both zooming in and zooming out. If either zooming in or zooming out is supported, then both must be supported.

D3DPTFILTERCAPS_LINEARMIPLINEAR

Trilinear interpolation between mipmaps. Performs bilinear filtering on the two nearest mipmaps, then interpolates linearly between the two colors to determine a final color.

D3DPTFILTERCAPS_LINEARMIPNEAREST

Linear interpolation between two point sampled mipmaps. Chooses the nearest texel from the two closest mipmap levels, then performs linear interpolation between them.

D3DPTFILTERCAPS_MIPLINEAR

Nearest mipmapping, with bilinear filtering applied to the result. Chooses the texel from the appropriate mipmap that has nearest coordinates, then performs a weighted average with the four surrounding texels to determine the final color.

D3DPTFILTERCAPS_MIPNEAREST

Nearest mipmapping. Chooses the texel from the appropriate mipmap with coordinates nearest to the desired pixel value.

D3DPTFILTERCAPS_NEAREST

Point sampling. The texel with coordinates nearest to the desired pixel value is used. This applies to both zooming in and zooming out. If either zooming in or zooming out is supported, then both must be supported.

Per-stage texture filtering flags
