Painless way to do 3D visualization

[Peter Beattie]

Hey folks,

I need to do the following relatively simple 3D programming:

I want to convert data from four-item tuples into 3D co-ordinates in a
regular tetrahedron. Co-ordinates come in sequences of 10 to 20, and the
individual dots in the tetrahedron need to be connected into
discontinuous lines. A single tetrahedron should contain at least two,
possibly more, such lines. I would like to show certain similarities in
the sequences/lines, eg by changing color, thickness, or maybe attaching
indeces to certain points in a particular sequence.

I'd welcome suggestions as to what might be the most painless way to
achieve this in Python. So far, I've only tinkered a little with
VPython, but the lack of any decent documentation has proved to be a
major turn-off.

TIA!
