Arrow keys!
Thanks @The_Grits for simplifying the original and sharing it. All I did was reverse the arrows (cause I thought they were backwards) and add some more points. With more points that are different colors it sometimes puts the smaller dots in front of the bigger dots which messes up the 3-D effect, but calculating the draw order would be complicated I'm thinking. Thanks for the original project too: 3D guide (complete) by @geocashing.
