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.

A Journey Through the Atmosphere

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.

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.

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. And if you want to render physically accurate visuals for alien planets, this is definitely the tutorial you’ve been looking for.

Volumetric Rendering: Surface Shading

Volumetric Rendering: Surface Shading

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.
