Defines constants that describe the supported texture-addressing modes.
Syntax
typedef enum _D3DTEXTUREADDRESS {
D3DTADDRESS_WRAP = 1,
D3DTADDRESS_MIRROR = 2,
D3DTADDRESS_CLAMP = 3,
D3DTADDRESS_BORDER = 4,
D3DTADDRESS_MIRRORONCE = 5,
D3DTADDRESS_FORCE_DWORD = 0x7fffffff
} D3DTEXTUREADDRESS;
Constants
- D3DTADDRESS_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.
- D3DTADDRESS_MIRROR
Similar to D3DTADDRESS_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); between 2 and 3, the texture is normal again, and so on.
- D3DTADDRESS_CLAMP
Texture coordinates outside the range [0.0, 1.0] are set to the texture color at 0.0 or 1.0, respectively.
- D3DTADDRESS_BORDER
Texture coordinates outside the range [0.0, 1.0] are set to the border color.
- D3DTADDRESS_MIRRORONCE
Similar to D3DTADDRESS_MIRROR and D3DTADDRESS_CLAMP. Takes the absolute value of the texture coordinate (thus, mirroring around 0), and then clamps to the maximum value. The most common usage is for volume textures, where support for the full D3DTADDRESS_MIRRORONCE texture-addressing mode is not necessary, but the data is symmetric around the one axis.
- D3DTADDRESS_FORCE_DWORD
Forces this enumeration to compile to 32 bits in size. This value is not used.
