P-152: Virtual World Concept Update 16: Spherical Terrain

I have succeeded in drawing one face of the quad sphere! I had made a slight error in the implementation of the mathematical equations, which is why it didn’t work before, but it is working now. This is a major step forward. I now need to draw all six faces of the cube, so that I can project them to form the completed quad sphere. In the images below I have copied and pasted several several faces and manually rotated them, to confirm that the edges line up correctly.

After I get the complete sphere drawn, I will need to apply a noise function to produce the actual detail of the terrain. With T3D’s terrain, this was easy, but with my new solution I am doing this completely from scratch, so I will likely need to apply some kind of smoothing function manually.

Then, I will need to look into texturing, collision detection, culling, and a whole host of optimisations!
