enum TexSampleComp

When sampling from a texture with comparison enabled, the sampler compares the sampled texel value against a reference value and returns a 0 or 1 based on the result. This is primarily useful for shadow mapping techniques, where a depth texture is sampled to determine if a surface is in shadow.

Enum Values


Always	Always returns 1, regardless of values.
Equal	Returns 1 if the reference value is equal to the sampled texel value.
Greater	Returns 1 if the reference value is greater than the sampled texel value.
GreaterOrEq	Returns 1 if the reference value is greater than or equal to the sampled texel value.
Less	Returns 1 if the reference value is less than the sampled texel value.
LessOrEq	Returns 1 if the reference value is less than or equal to the sampled texel value.
Never	Always returns 0, regardless of values.
None	No comparison is performed, the texture is sampled normally. This is the default behavior for most textures.
NotEqual	Returns 1 if the reference value is not equal to the sampled texel value.
