SampleCmpLevelZero::SampleCmpLevelZero(S,float,float,uint) function for TextureCubeArray
Samples a texture on mipmap level 0 only and compares the result to a comparison value. Returns status about the operation.
Syntax
DXGI_FORMAT SampleCmpLevelZero(
in SamplerState S,
in float Location,
in float CompareValue,
out uint Status
);
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.
Texture-Object Type Parameter Type Texture1D float Texture1DArray, Texture2D float2 Texture2DArray, Texture3D, TextureCube float3 TextureCubeArray float4 -
CompareValue [in]
-
Type: float
A floating-point value to use as a comparison value.
-
Status [out]
-
Type: uint
The status of the operation. You can't access the status directly; instead, pass the status to the CheckAccessFullyMapped intrinsic function. CheckAccessFullyMapped returns TRUE if all values from the corresponding Sample, Gather, or Load operation accessed mapped tiles in a tiled resource. If any values were taken from an unmapped tile, CheckAccessFullyMapped returns FALSE.
Return value
Type: DXGI_FORMAT
The texture format, which is one of the typed values listed in DXGI_FORMAT.
