Hi Denis,

For the matrix stuff, see Numeric Python:

    http://www.pfdubois.com/numpy/

I'm positive that it has functions for doing Matrix calculations like
determinant and rank stuff.


For 3d stuff, you have a few choices, and you can find out about them from
the Vaults of Parnassus:

In particular, you may want to check out VPython:

    http://vpython.org/

I haven't had too much experience with VPython myself, but I've heard that
it's a very nice module for doing visualization and 3d stuff.


You can look at one concrete application of Numeric Python and VPython:
Arthur Siegel's 'PyGeo' project applies both modules to spectacular
effect:

I hope this helps!
