This repository contains several demonstrations of what you can do with IntenseLogic.

• Bouncing Lights: A heightmap with several bouncing spheres, every single one is a point light source. The physics is performed by Bullet Physics.
• Shadertoy: A clone of the functionality offered by shadertoy.com. Many of the uniforms are provided. When you save a file, it instantly detects this and reloads the shader while it's running. Detecting shader reloads is performed through libuv.
• Lighting: An attempt at demonstrating the physically-based rendering pipeline in IL.

• Bullet
• SDL 2
• libuv
• libepoxy
• libpng
• tup

Just run tup.

The only one of these which really has command line options is shadertoy, which is invoked like:

shadertoy -f=some_shader.frag

This will load any shaders in the shadertoys/ directory, which is where you should put any new shaders you make.

You don't need to restart shadertoy if you edit your shader, it will reload automatically.
