My next step is to start generating textures and geometry. I've been taking a little break, playing some games (Civ4, Dawn of war, Fear). I fixed that seam problem, it was just clamping, I just had to set it in the shader (.fx) not the render state. I'm still a bit new to shaders. I also managed to map an image of the earth to my globe which looks kinda neat, though the scale is still a little off, and there's some nasty seams between quadrants. It might be a few more days up to a week before a decent update, still taking my break.
