SampleCmp::SampleCmp(S,float,float,float) function for TextureCubeArray
Samples a texture, using a comparison value to reject samples, with an optional value to clamp sample level-of-detail (LOD) values to.
Syntax
DXGI_FORMAT SampleCmp(
in SamplerState S,
in float Location,
in float CompareValue,
in float Clamp
);
Parameters
-
S [in]
-
Type: SamplerState
A Sampler state. This is an object declared in an effect file that contains state assignments.
-
Location [in]
-
Type: float
The texture coordinates. The argument type is dependent on the texture-object type.

CompareValue [in]
-
Type: float
A floating-point value to use as a comparison value.
-
Clamp [in]
-
Type: float
An optional value to clamp sample LOD values to. For example, if you pass 2.0f for the clamp value, you ensure that no individual sample accesses a mip level less than 2.0f.
Return value
Type: DXGI_FORMAT
