But graphics programmers tend to be exposed to either GL (which uses column-major storage and column vectors) or D3D (which used row-major storage and row vectors in its fixed function pipeline, and still uses that convention in its examples), so they think the two ...Thu, 22 Jan 2026 05:57:00 GMThttps://fgiesen.wordpress.com/2016/04/03/sse-mind-the-gap/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 SoA layout to begin with.Sun, 02 Nov 2025 03:51:00 GMThttps://fgiesen.wordpress.com/page/8/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 the point that it’s often faster to transpose, perform a vertical filter, and then transpose back.Fri, 19 Sep 2025 23:34:00 GMThttps://fgiesen.wordpress.com/2013/03/04/speculatively-speaking/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 4×4 matrix transpose is fairly easy to do in SSE, and Intel’s intrinsics header file even comes with a macro that implements it.Thu, 03 Jul 2025 10:34:00 GMThttps://fgiesen.wordpress.com/2013/05/13/trig-identities-from-complex/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 the signs and such go when trying to memorize this directly. At least for me, what worked way better is this: spend a few hours familiarizing yourself with complex numbers if you haven’t done so already ...Fri, 16 Jan 2026 15:37:00 GMThttps://fgiesen.wordpress.com/2023/03/19/notes-on-ffts-for-implementers/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 permutation usually involves some kind of SIMD transpose, and moving some of the math across that transpose boundary separates what would otherwise be intra ...Wed, 29 Oct 2025 03:20:00 GMThttps://fgiesen.wordpress.com/2011/07/02/a-trip-through-the-graphics-pipeline-2011-part-2/This post is part of the series “A trip through the Graphics Pipeline 2011”.
