A 3D engine primer/landscape/lighting effects

This example is kind of a compilation. It shows how to create a 3D view and allow you to rotate a solid cube. I also created a method to create landscape meshes from an image(voxel to polygon?). If 3D is not your thing, you may be able to use the landscape code to create a lighting effects tool similar to photoshop. Source is somewhat commented, Includes Back Face Culling; Lighting using Point lights in space; One single API to draw filled polygons.
