Last time , we looked at precomputing irradiance using spherical harmonics and how the math can be simplified compared to the expressions co...

 Today, we're picking up right were we left last post . We are looking at building our irradiance map. As a refresher, the irradiance ma...

This is the first post in a series dedicated to Image-Based Lighting. This is a very common technique in modern videogames used to implement...

In the last post of this series, we spent some time optimizing aabb-ray intersections. In this post, we will do the same for triangles, and...

This post is about optimizing the AABB tree that we're using as our main acceleration structure. I will use the polly scene from pre...

Going from 1 triangle to many triangles is a trivial thing to do. At least if you don't care about performance at all. Just add a v...

Following on the idea of my last post, today we're building on a very important matter: Intersecting triangles. Or more specifically, ...
