Atmospheric Scattering Shader
This tutorial finally concludes our journey to simulate Rayleigh Scattering for a planet’s atmosphere. The next (and final) part will show how to change the shader to also include an additional type of scattering, known as Mie Scattering.

CD-ROM Shader: Diffraction Grating – Part 1
This post will guide you through the creation of a shader that reproduces the rainbow reflections that can be seen on CD-ROMs and DVDs. This tutorial is part of a longer series on physically based iridescence. You can find the complete series here: A link to download the Unity project used in this series is…

Fast Subsurface Scattering in Unity (Part 1)
Most (if not all) optical phenomena that materials exhibit can be replicated by simulating how the individual rays of light propagate and interact. This approach is referred in the scientific literature as ray tracing, and it is often too computationally expensive for any real-time application. Most modern engines rely on massive simplifications that, despite being…

Improving the Rainbow – Part 2
In the previous part of this tutorial, Improving the Rainbow – Part 1, we have seen different techniques to reproduce the colours of the rainbow procedurally. Solving this problem efficiently will allow us to simulate physically based reflections with a much higher fidelity. The purpose of this post is to introduce a novel approach that…

Improving the Rainbow – Part 1
Our journey to photorealism requires us to understand not only how light works, but also how we perceive colours. How many colours are in the rainbow? And why pink is not one of them? Those are some of the questions that this post will address. You can find the complete series here: A link to…
