This repository aims to demonstrate a simple implementation of a GLSL based OpenGL raycaster.

Video of an early version:
On load a voxel volume is generated consisting of:
- A grey bottom floor layer.
- Two green "grass" layers.
- A number of blue columns that are randomly placed.
- A set of six coloured blocks.
- A red sphere.
The whole scene is volumetric and can be changed very easily in the code.
Use the arrow keys to move around.
There is a day/night cycle that occurs about once a minute.
This project was inspired by the WebGL GLSL raymarcher written by Rye Terrell: https://github.com/ivl/Voxgrind
