Web14 de mai. de 2024 · Well, textureGather is already a slight bit hacky in that it forces you to just a single channel for the apparently sole reason that it can't return 4 vec4 s API-wise. So I'd guess the lack of a textureGather for 3D textures might be simply due to the interface problems of returning 8 values instead of 4 from a function. – Christian Rau WebDescription. textureGather returns the value: vec4(Sample_i0_j1(P, base).comp, Sample_i1_j1(P, base).comp, Sample_i1_j0(P, base).comp, Sample_i0_j0(P, …

WebWrite to the output texture; Step 1 is the key here. In the pixel shader version, the source image is sampled multiple times per pixel. In the compute shader version, each source texel is read only once inside a work group. Texture reads usually use a tile-based cache, but this cache is still much slower than shared memory.
