D3DTEXTUREMINFILTER

The D3DTEXTUREMINFILTER enumerated type defines texture-minification filtering modes for a texture stage.

typedef enum _D3DTEXTUREMINFILTER {
    D3DTFN_POINT        = 1,
    D3DTFN_LINEAR       = 2,
    D3DTFN_ANISOTROPIC  = 3,
    D3DTFN_FORCE_DWORD  = 0x7fffffff,
} D3DTEXTUREMINFILTER; 

D3DTFN_POINT

Point filtering. The texel with coordinates nearest to the desired pixel value is used.

D3DTFN_LINEAR

Bilinear interpolation filtering. A weighted average of a 2×2 area of texels surrounding the desired pixel is used.

D3DTFN_ANISOTROPIC

Anisotropic texture filtering. Compensates for distortion caused by the difference in angle between the texture polygon and the plane of the screen.

D3DTFN_FORCE_DWORD

Forces this enumeration to compile to 32 bits in size. This value is not used.

Remarks

Set a texture stage's magnification filter by calling the IDirect3DDevice7::SetTextureStageState method with the D3DTSS_MINFILTER value as the second parameter and one of the members of this enumeration as the third parameter.
