D3D10_DDI_TEXTURE_ADDRESS_MODE enumeration

The D3D10_DDI_TEXTURE_ADDRESS_MODE enumeration type contains values that identify the texture address mode of a sampler.

Syntax

typedef enum D3D10_DDI_TEXTURE_ADDRESS_MODE { 
  D3D10_DDI_TEXTURE_ADDRESS_WRAP        = 1,
  D3D10_DDI_TEXTURE_ADDRESS_MIRROR      = 2,
  D3D10_DDI_TEXTURE_ADDRESS_CLAMP       = 3,
  D3D10_DDI_TEXTURE_ADDRESS_BORDER      = 4,
  D3D10_DDI_TEXTURE_ADDRESS_MIRRORONCE  = 5
} D3D10_DDI_TEXTURE_ADDRESS_MODE;

Constants

D3D10_DDI_TEXTURE_ADDRESS_WRAP

Tile the texture at every integer junction. For example, for u values between 0 and 3, the texture is repeated three times; no mirroring is performed.

D3D10_DDI_TEXTURE_ADDRESS_MIRROR

Similar to D3D10_DDI_TEXTURE_ADDRESS_WRAP, except that the texture is flipped at every integer junction. For u values between 0 and 1, for example, the texture is addressed normally; between 1 and 2, the texture is flipped (mirrored); and between 2 and 3, the texture is normal again, and so on.

D3D10_DDI_TEXTURE_ADDRESS_CLAMP

Texture coordinates outside the range [0.0, 1.0] are set to the texture color at 0.0 or 1.0, respectively.

D3D10_DDI_TEXTURE_ADDRESS_BORDER

Texture coordinates outside the range [0.0, 1.0] are set to the border color.

D3D10_DDI_TEXTURE_ADDRESS_MIRRORONCE

Similar to D3D10_DDI_TEXTURE_ADDRESS_MIRROR and D3D10_DDI_TEXTURE_ADDRESS_CLAMP. Takes the absolute value of the texture coordinate (thus, mirroring around 0), and then clamps to the maximum value. The most common usage of D3D10_DDI_TEXTURE_ADDRESS_MIRRORONCE is for volume textures, where support for the full D3D10_DDI_TEXTURE_ADDRESS_MIRRORONCE texture-addressing mode is not necessary, but the data is symmetric around the one axis.
