Constants

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.

Remarks

These flags are used to set the value of the D3DRS_ZFUNC, D3DRS_ALPHAFUNC, and D3DRS_STENCILFUNC render states for the CONST_D3DRENDERSTATETYPE enumeration.
