[SPIR-V][vk::SampledTexture] #5. Add remaining .Sample...() methods for vk::SampledTexture2D` type. (#8098)
Part of #7979 Implement remaining sample methods methods for `vk::SampledTexture2D`: ```hlsl float Object.SampleCmp(float Location, float CompareValue, [, int Offset], [, float Clamp] [, out uint Status]); float Object.SampleCmpLevelZero(float Location, float CompareValue, [, int Offset], [, out uint Status]); float Object.SampleCmpLevel(float Location, float CompareValue, float LOD, [, int Offset], [, out uint Status]); float Object.SampleGrad(float Location, float DDX, float DDY, [, int Offset], [, float Clamp] [, out uint Status]); float Object.SampleCompGrad(float Location, float CompareValue, float DDX, float DDY, [, int Offset], [, float Clamp] [, out uint Status]); float Object.SampleCompBias(float Location, float CompareValue, float Bias, [, int Offset], [, float Clamp] [, out uint Status]); PARAM_TYPE Object.SampleBias(float Location, float Bias, [, int Offset], [, float Clamp], [, out uint Status]); PARAM_TYPE Object.SampleLevel(float Location, float LOD, [, int Offset], [, out uint Status]); ``` --------- Co-authored-by: Damyan Pepper <[email protected]> Co-authored-by: copilot-swe-agent[bot] <[email protected]> Co-authored-by: Ashley Coleman <[email protected]> Co-authored-by: kpyzhov <[email protected]> Co-authored-by: Konstantin <[email protected]> Co-authored-by: Steven Perron <[email protected]> Co-authored-by: Alex Sepkowski <[email protected]>
