D3DCULL

The D3DCULL enumerated type defines the supported culling modes used with the D3DRENDERSTATE_CULLMODE render state. These define how back faces are culled when rendering a geometry.

typedef enum _D3DCULL { 
    D3DCULL_NONE = 1, 
    D3DCULL_CW   = 2, 
    D3DCULL_CCW  = 3, 
    D3DCULL_FORCE_DWORD   = 0x7fffffff, 
} D3DCULL; 

D3DCULL_NONE

Do not cull back faces.

D3DCULL_CW

Cull back faces with clockwise vertices.

D3DCULL_CCW

Cull back faces with counterclockwise vertices.

D3DCULL_FORCE_DWORD

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