TextureCubeArray::GatherGreen(S,float,uint) function
Returns the green components of the four texel values that would be used in a bi-linear filtering operation, along with tile-mapping status.
Syntax
TemplateType GatherGreen(
in SamplerState S,
in float4 Location,
out uint Status
);
Parameters
-
S [in]
-
Type: SamplerState
The zero-based sampler index.
-
Location [in]
-
Type: float
The sample coordinates (u,v).
-
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: TemplateType
A four-component value whose type is the same as the template type.
Remarks
The texture samples can be used for bilinear interpolation.
This function is supported for the following types of shaders:
| Vertex | Hull | Domain | Geometry | Pixel | Compute |
|---|---|---|---|---|---|
| x | x | x | x | x | x |
