The Mathematics of 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…

The Theory Behind Atmospheric Scattering
This is the second part of the tutorial on volumetric atmospheric scattering. In this post we will start deriving the equations that govern this complex, yet beautiful optical phenomenon. You can find all the post in this series here: You can download the Unity package for this tutorial at the bottom of the page.

Volumetric Atmospheric Scattering
If you have lived long enough on planet Earth, you might have wondered why the sky is usually blue, yet red at sunset. The optical phenomenon which is (mostly) responsible for that is called Rayleigh scattering. This tutorial will explain how to model atmospheric scattering to reproduce many of the visual effects that planets exhibit.…

Understanding Geographical Coordinates
This series introduces the concept of trilateration. This technique can be applied to a wide range of problems, from indoor localisation to earthquake detection. This first post provides a general introduction to the concept of geographical coordinates, and how they can be effectively manipulated. The second post in the series, Positioning and Trilateration, will cover the actual…

Fractals 101: The Mandelbrot Set
This is the second part of Fractals 101, a series of tutorial dedicated to fractals. This post will investigate two popular fractals: the Mandelbrot set and its 3D cousin, the Mandelbulb.
