javidx9 demonstrates how to implement perspective correct texture mapping, scan-line triangle rasterization, and depth buffers in a custom C++ 3D engine.

By popular request I decided to have a go at implementing texturing in my command prompt 3D engine. I'm quite pleased with the results! This video shows perspective correct texture sampling, scan-line triangle rasterizing and depth buffers.

Perspective-correct interpolation only works for some faces of a cube Hi, is the guy from the raylib renderer again. These last days i was trying to implement texture mapping on the renderer i am making, but i cant get the perspective-correct interpolation to work. I tried first with the method described in scratchapixel, but it didnt work at all, then i tried with the method of this video, and it only works for some faces of a cube, but the rest of faces are not only distorted but the texture is still mapped like i was doing affine mapping: 2 of the faces that have the problem One face is rendered correctly while in the other the texture gets squished The thing that confuses me is tha…
