The goal of this project is to write a proof of concept geometry shader that generates grass.

• W: Move Forward
• S: Move Backward
• A: Strafe Left
• D: Strafe Right
• Escape: Close the simulation
• Mouse: Moves the view around

The idea is to use barycentric coordinates and a Mersenne Twister to generate random points on each triangle. From these random points, we can generate geometry that is shaped like blades of grass.

To generate randomness I ported Mutsuo Saito's and Makoto Matsumoto's TinyMT mersenne twistter to GLSL. I'm not quite sure if I nailed all of the casting that goes on in TinyMT, because GLSL isn't as forgiving with its Type System. The original implementation can be found here.

• Java 8
• Maven 3 (if building from source)
