Jul 9, 2013 · For example, when implementing 2D separable filters, the “vertical” direction (filtering between rows) is usually easy, whereas “horizontal” (filtering between columns within the same …

Aug 8, 2024 · However, these are the passes right next to the input/output permutation, and combining the early special-case passes with the data permutation tends to solve problems in both: the data …

Feb 12, 2012 · Row-major vs. column-major is just a storage order thing and doesn’t have anything to do with what kind of vectors you use. But graphics programmers tend to be exposed to either GL …

Apr 3, 2016 · If you want good SIMD performance, don’t lean on horizontal and dot-product style operations; process data in batches (not just one vec4 at a time) and transpose on input, or use a …

For example, when implementing 2D separable filters, the “vertical” direction (filtering between rows) is usually easy, whereas “horizontal” (filtering between columns within the same register) is trickier – to …

Mar 4, 2013 · Luckily, that’s not too hard: converting data from AoS to SoA is essentially a matrix transpose, and our typical use case happens to be 4 separate 4-vectors, i.e. a 4×4 matrix; luckily, a …

May 13, 2013 · There’s tons of useful trig identities. You could spend the time to learn them by heart, or just look them up on Wikipedia when necessary. But I’ve always had problems remembering where …
