This is just a brief summary, how I'm trying to do it now. In case somone ever encouters a problem like this...
For the 2D part, I'm going with matplotlib, which seems to do, what I want. The 3D is currently donw be vpython, which is not great, but sufficient... Maybe I will switch when I find something better... ;) Thanks anyway. -- http://mail.python.org/mailman/listinfo/python-list
