I have been told something like a 3D spreadsheet is difficult to program. I am developing a computer game that requires a 3d matrix, like a 3d spreadsheet, so you have X, Y, and Z co-ordinates. The action would be at these intersections, where one XYZ would be one color, say a small sphere placed there, glowing blue and other XYZ's with small spheres glowing red, and they can be turned off an on in either color depending on the moves of the game. Can anyone tell me how to do such a thing? I am not a programmer, only a bit of VB and HP48 and casio programmable calculator stuff. The matrix size would be under 20X20X20 so it's not like an infinite thing at all. Thanks in advance.
