# 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
