D3DTEXTUREMAGFILTER

The D3DTEXTUREMAGFILTER enumerated type defines texture magnification filtering modes for a texture stage.

typedef enum _D3DTEXTUREMAGFILTER {
    D3DTFG_POINT        = 1,  
    D3DTFG_LINEAR       = 2,  
    D3DTFG_FLATCUBIC    = 3,  
    D3DTFG_GAUSSIANCUBIC= 4,  
    D3DTFG_ANISOTROPIC  = 5,  
    D3DTFG_FORCE_DWORD  = 0x7fffffff,  
} D3DTEXTUREMAGFILTER;
 

Members

D3DTFG_POINT

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

D3DTFG_LINEAR

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

D3DTFG_FLATCUBIC

Not currently supported; do not use.

D3DTFG_GAUSSIANCUBIC

Not currently supported; do not use.

D3DTFG_ANISOTROPIC

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

D3DTFG_FORCE_DWORD

Forces this enumerated type to compile to 32 bits in size.

Remarks

You set a texture stage's magnification filter by calling the IDirect3DDevice3::SetTextureStageState method with the D3DTSS_MAGFILTER value as the second parameter, and one of members of this enumeration as the third parameter.
