| Nov 14, 2017 at 18:33 | comment | added | ggambetta | I'm on the "split the quad into two triangles" camp. I've written about how interpolation works in a triangle in some detail here: gabrielgambetta.com/computer-graphics-from-scratch/… It doesn't use barycentric coordinates at all, so it complements the other answer nicely :) | |
| Nov 2, 2017 at 16:28 | comment | added | Alan Wolfe | From the question title I thought you were asking about bilinear interpolation. For other folks who came here looking for information on that, here's a link (but feel free to explicitly ask a question too) blog.demofox.org/2015/04/30/… | |
