_Texture<T, Shape, isArray, isMS, sampleCount, access, isShadow, isCombined, format>.queryFootprintCoarseGrad
Description
Query the footprint that would be accessed by a texture sampling operation.
This operation queries the footprint that would be accessed by a comparable call to:
t.SampleGrad(sampler, coords, dx, dy);
Signature
TextureFootprint<Shape.dimensions> _Texture<T, Shape, isArray, isMS, sampleCount, access, isShadow, isCombined, format>.queryFootprintCoarseGrad( uint granularity, SamplerState sampler, vector<float, Shape.dimensions> coords, vector<float, Shape.dimensions> dx, vector<float, Shape.dimensions> dy) where Shape : __ITextureShape where isArray == 0 where isMS == 0 where access == 0 where isCombined == 0;
