After reading these lines I couldn't wait to lay my hands on
"index_set.pyx", uncomment those lines and start plotting some good
stuff.
I recently downloaded the Vmware version, since Fedora 8 won't let me
render 3D (just 2D, I guess I'm gonna have to try the Sun JDK), and
I've been pleased with the quality of the plots, there's a lot of
potential there, but I still miss the 'good 'ol mesh'. My experience
with Unix editing tools (ed, sed, grep, etc.) has been so superficial
that I must confess I find it easier to click the Kwrite icon than
trying to understand search methods or regular expressions. The best I
could achieve was to dump the file to screen (using w3m and Firefox
opening a new tab for me) and that was it. Look but don't touch. Any
suggestions??
