FINALLY 🥳 after days of debugging I fixed my python implementation of the new ADAA algo proposed in this paper for wavetable oscillators : https://ieeexplore.ieee.org/document/9854137

Now that it's working let's try to tweak things and move to a C++ version 👀

PS : graph below is w/o oversampling

approach is better than the old one. Or you're needing something extra in your lines (#antialiasing, different widths, #gradients, etc). There's just no "get-out-of-ridiculously-low-level-optimization free" card. You do it or you underperform.

Today in #graphics you still need to optimize, but at far higher levels; the vast majority of people are totally divorced from the #hardware and the drawing of low-level primitives. But "Back In My Day...", that just wasn't an option!

La technologie d'antialiasing TAA pose problème pour les textes !

Exemple ici dans le jeu Pinball FX (en accès anticipé) et avec FXAA pour comparer.

TAA a son lot de critiques et, dans un cas comme celui-ci, je peux les comprendre.

Il y a même un subreddit anti-TAA, c'est dire : https://www.reddit.com/r/FuckTAA/
