Colliding galaxies in 3-D object? [message #38111] Tue, 17 February 2004 16:25

Hi, Folks -
For an astrophysics class I'm teaching, I'm having the students write a
simple simulation of colliding galaxies (in IDL). They've got the basic code
working in standard graphics mode, with color coding for the stars in the
two galaxies and front and side views of the collision as it unfolds over
hundreds of time steps. What I'd like to do next is to view the collision in
3-D with mouse control over the viewing angle and (ideally) the zoom as
well. The input information is a set of arrays of 3-D coordinates for N red
stars and N green stars, for M time steps. Can someone point me to the 3-D
object routine in IDL that should be able to handle this, and (better yet)
alert me to any gotchas I should worry about as I try to implement this?

Thanks for any suggestions!
