    [ TDx_3DI_Library ]     [ next: D3DCOLOR ]     [ prev: D3DCLIPSTATUS ]

    Text and description quoted verbatim from Microsoft DirectX 7 help file, included here for convenient reference.

    The D3DCMPFUNC enumerated type defines the supported compare functions for the D3DRENDERSTATE_ZFUNC, D3DRENDERSTATE_ALPHAFUNC, and D3DRENDERSTATE_STENCILFUNC render states.

    typedef enum _D3DCMPFUNC {
    D3DCMP_NEVER = 1,
    D3DCMP_LESS = 2,
    D3DCMP_EQUAL = 3,
    D3DCMP_LESSEQUAL = 4,
    D3DCMP_GREATER = 5,
    D3DCMP_NOTEQUAL = 6,
    D3DCMP_GREATEREQUAL = 7,
    D3DCMP_ALWAYS = 8,
    D3DCMP_FORCE_DWORD = 0x7fffffff,
    } D3DCMPFUNC;

    D3DCMP_NEVER
    Always fail the test.
    D3DCMP_LESS
    Accept the new pixel if its value is less than the value of the current pixel.
    D3DCMP_EQUAL
    Accept the new pixel if its value equals the value of the current pixel.
    D3DCMP_LESSEQUAL
    Accept the new pixel if its value is less than or equal to the value of the current pixel.
    D3DCMP_GREATER
    Accept the new pixel if its value is greater than the value of the current pixel.
    D3DCMP_NOTEQUAL
    Accept the new pixel if its value does not equal the value of the current pixel.
    D3DCMP_GREATEREQUAL
    Accept the new pixel if its value is greater than or equal to the value of the current pixel.
    D3DCMP_ALWAYS
    Always pass the test.
    D3DCMP_FORCE_DWORD
    Forces this enumeration to compile to 32 bits in size. This value is not used.
