TextureCube::Sample(S,float,float,uint) function

Samples a texture with an optional value to clamp sample level-of-detail (LOD) values to, and returns status of the operation.

Syntax

DXGI_FORMAT Sample(
  in  SamplerState S,
  in  float        Location,
  in  float        Clamp,
  out uint         Status
);

Parameters

S [in]

A Sampler state. This is an object declared in an effect file that contains state assignments.

Location [in]

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

 

Clamp [in]

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.

Status [out]

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

The texture format, which is one of the typed values listed in DXGI_FORMAT.
