This is a fascinating topic, especially when considering how this was achieved back in the days. We now take it for granted, but this was not a simple feature to have in your game in 199x ( x<6 ;) ).

For anyone interested: I have a detailed write up on the topic here in the context of 1990s renderers https://github.com/sylefeb/tinygpus/tree/main?tab=readme-ov-... ; a video discussing texture mapping with a hardware twist https://youtu.be/2ZAIIDXoBis?si=MvQXH2ltqWmvFMdt&t=1072 ; and have a shadertoy to compare perspective correct texture mapping on/off https://www.shadertoy.com/view/ftKSzR
