WebbUsually avoid horizontal stuff with SIMD. SIMD vec != geometry vec. Using only 3 out of 4 elements of a SIMD vector is usually a bad idea because it usually means you're using a single SIMD vector to hold a single geometry vector, instead of three vectors of 4 x coords, 4 y coords, and 4 z coords.. Shuffles / horizontal stuff mostly costs extra instructions … Webb30 jan. 2024 · SIMD stands for Single Instruction, Multiple Data.
