I've just heard (though havn't confirmed myself) that the free OpenGL

Many of the problems with Alpha Linux maths libraries were ironed out
for the Titanic. Animation for this movie was done on 160 Alpha, over
100 of which were running Linux (the rest NT). Take a look at the
February 1998 issue of Linux Journal (www.linuxjournal.com)
