    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 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. You can find all the post in this series here: You can download the Unity package for…

    This post describes how to model the density of the atmosphere at different altitude. This is a critical step, since the atmospheric density is one of the parameters necessary to correctly calculate the Rayleigh scattering.

    This post introduces the Mathematics of Rayleigh Scattering, which is the optical phenomenon that causes the sky to appear blue. The equations derived in this tutorial will be translated into shader code in the next tutorial. You can find all the post in this series here: You can download the Unity package for this tutorial…
