This enumeration provides values that identify comparison functions for various render states. For more information, see D3DMRENDERSTATETYPE.

Syntax

typedef enum _D3DMCMPFUNC {
  D3DMCMP_NEVER        = 1,
  D3DMCMP_LESS         = 2,
  D3DMCMP_EQUAL        = 3,
  D3DMCMP_LESSEQUAL    = 4,
  D3DMCMP_GREATER      = 5,
  D3DMCMP_NOTEQUAL     = 6,
  D3DMCMP_GREATEREQUAL = 7,
  D3DMCMP_ALWAYS       = 8,
  D3DMCMP_FORCE_ULONG  = 0x7fffffff,
} D3DMCMPFUNC;

Elements

• D3DMCMP_NEVER
  The comparison is always FALSE.

• D3DMCMP_LESS
  The comparison is TRUE if the input value is less than the reference value.

• D3DMCMP_EQUAL
  The comparison is TRUE if the input value and reference value are equal.

• D3DMCMP_LESSEQUAL
  The comparison is TRUE if the input value is less than or equal to the reference value.

• D3DMCMP_GREATER
  The comparison is TRUE if the input value is greater than the reference value.

• D3DMCMP_NOTEQUAL
  The comparison is TRUE if the input value is not equal to the reference value.

• D3DMCMP_GREATEREQUAL
  The comparison is TRUE if the input value is greater than or equal to the reference value.

• D3DMCMP_ALWAYS
  The comparison is always TRUE.

• D3DMCMP_FORCE_ULONG
  Forces the compiler to interpret the enumeration as a ULONG value. This value is not used directly in Direct3D Mobile programming.

Remarks

Values from this enumeration are used in the D3DMRS_ZFUNC render state.
