Okay.  This is my final attempt here.  I changed my email address, but for
some reason the message kept it.  No doubt my mistake.  If my email address
still stays, so does this message.  Very sorry to be making a mess of this
fine newsgroup.  Really though, I've slipped up here or there, but I don't
think I've received one piece of spam in about nine months with my new
email address.  So yes, in fact, it is worth it.  But here's the synopsis
of the original message:

Here's my attempt at the 'Visual Simulation of Smoke' paper (google it!).  I
have just about everything in place - vorticity confinement, a conjugate
gradient solver, the semi-lagrangian scheme with cubic interpolation, but
the obvious next step is to add a third dimension.  This shouldn't be too
difficult since everything is completely analogous.  In fact, this started
out as three dimensional, but it was too difficult and slow to debug, so I
reduced it to two.  The latest version adds a lot more detail, but the mpeg
compression still causes it to lose a fair amount.  Oh well, it will look
better in THREE DIMENSIONS!!  (read with thunderous voice).  Sorry, I'm
looking forward to a third dimension though.  I'll post the code when it's
in pretty good shape, but it's not too pretty since my c++ experience is
basically limited to what you see here.

As a reply to a reply to my previous message, sorry it's not in sdl, but 1)
that would take months in POV alone and 2) I don't have the capability to
patch POV.  I can't even get it to compile on my own.  Maybe some day.

 - Ricky
