    Introduction If you are working in the field of Computer Science, chances are you might have encountered quite a lot of technical terms and foreign names, such as Dijkstra and Nyquist. And chances are that you have learnt a good part of them solely from books. And there is nothing more embarrassing than being in…

    This third instalment on Volumetric Rendering will explain how to shade volumes in a realistic fashion. This essential step is what gives three-dimensionality to the flat, unlit shapes that have been generated so far with raymarching. You can find here all the other posts in this series: The full Unity package is available at the end of this article. 📦

    Part 1, Part 2, Part 3, Part 4, Part 5, [download the Unity3D package] Why is it colder at the poles and hotter on the equator? This question, which seems completely unrelated to shaders, is actually fundamental to understand how lighting models work. As explained in the previous part of this tutorial, surface shaders use a mathematical model…

    Part 1, Part 2, Part 3, Part 4, Part 5 This is the second part of a series of posts on Unity3D shaders, and it will focus on surface shaders. As previously mentioned, shaders are special programs written in a language called Cg / HLSL which is executed by GPUs. They are used to draw triangles of your 3D…
