 /**
- * This terrain generator generates a simple terrain, similar to the basic
+ * Class will generate a terrain mesh from a TerrainMap
- * terrain used in my previous tutorials. The difference here is in the shader
- * programs, with the use of the "flat" type qualifier when passing the colour
- * from vertex shader to fragment shader. This stops the colour being
- * interpolated over each triangle, and instead the entire triangle uses the
- * colour value from just one of the vertices, the "provoking" vertex. This is
- * by default the last specified vertex of the triangle, but it's possible to
- * make it use the first vertex instead.
