Shaders
In general I work from the single learning.fs file. Additional branches exist for lessons & experiences I've found to be particularly educational.
Getting started
I use the excellent glslViewer and sublime-glslViewer tools created by patriciogonzalezvivo for live-coding these exercises.
The repos also contain pertinent documentation and usage guidelines.
After you've installed those packages:
git clone https://github.com/shiplet/shaders.git
cd shaders
glslViewer learning.fs
Then open learning.fs in Sublime and you're good to go! The glslViewer will update every time you save the file.
