# Unity Planet Rendering

A full scale planetary rendering in Unity 3D. Using precomputed atmospheric scattering as an image effect. Generating large planets with GPU noise, using compute shaders.

Atmosphere Scattering Based on Eric Bruneton's [Precomputed Atmospheric Scattering](https://www.youtube.com/watch?v=0I7Af2Ev5iQ)

# Instructions

The main scene is called `PlanetSphereTest`. 

The camera Controls are as follows:

* E/Q - row camera

* W/A/S/D - move camera

* Mouse Scroll - Increase/Decrease camera speed

* Space - Show/Hide mouse

* C - Take Screenshot at Double the Screen Resolution

* X - Exit Application

Updated to Unity 2019.2.8f1

# Requirements 

* A GPU with compute shader capability

* A GPU with async GPU reading capability
