The elements are retrieved in the form of unsigned integers with sizes matching the size of the full elements. They retrieve the four elements that have been sampled with bilinear filtering using Sample. Raw gathers give the control to the author by retrieving the raw element data without any conversion. Not only was this limited to a single channel, but it involved implicit conversions and other processing they had no control over. Gather operations grant the ability to retrieve individual channels of the sampled elements. ![]() ![]() Raw Gatherĭevelopers have long requested more control over how sampled elements are processed. SM 6.7 adds a collection of useful texture capabilities that fill in gaps the capabilities of certain texture operations as well as adding versatile new ones collectively referred to as Advanced Texture Operations. Feature Details Advanced Texture Operations It is still a work in progress and not yet available in any release, but implementation and updates will be showing up in the DXC Github Repository. Shader Model 6.7 expands texture, quad, and wave shader capabilities in response to requests from HLSL users. Microsoft and its partners are excited to announce the ongoing development of the latest HLSL Shader Model, 6.7!
