OpenGL Terrain and Grass Rendering Part 1

**This project is very much a work in progress** Student project from the Guildhall at SMU. The demo displays a terrain created from a height map and tessellated more or less depending on the current LOD. Grass is rendered using OpenGL's geometry shader. Positions for each grass leaf is stored in a VBO which is later rendered as points. These points become leafs when the geometry shader creates the leaf''s triangle strip geometry. Height map generated with World Machine.
