In my deferred pipeline I would like to sample with gatherRed the four pixels representing the same screen space location for each quarter. Second and third ones, more important, involve using GatherRed instructions, both on the shadow mask and the depth buffer (both are one-channel textures), to save on sampling instructions. The argument type is dependent on the texture-object type. Every once in a while I am in need to use one of those Gather functions from DirectX 11's HLSL library. Which means that 0. The type of the sampler corresponds to the type of the texture that can be used by that sampler. More info. As far as i've gathered, HLSL is more closely related to assembly code than a high level language as far as the interpretation by hardware goes. Returns the red components of the four texel values that would be used in a bi-linear filtering operation. Its very similar to HLSL. Instead, the approach both SPIR-V and Metal Shading Language (via [[user(n)]] ) take is to assign an identifier to each stage in/out variable, and use the assignments to match the variables between shader stages.
