[sage-support] plot3d doesn't display.

2009-11-29 Thread Francois Maltey
Hello,

I try to use the 3d plot but I can't.

The first command is perfect.
The second opens no new display and I can continue other calculus after.

I use a sage 4.2 version in a emacs windows in gnome box. The 
distribution is an ubuntu.

show( line([(1,2), (1,0), (3,1), (2,1)], color='red'))
show( line3d([(1,2,3), (1,0,-2), (3,1,4), (2,1,-2)], color='red'))

What am I missing please...

Francois

Installing Jmol may help. It's used to show the 3d stuff in a
rotatable manner. That said, I think it should be using tachyon if
Jmol isn't installed.

As far as I remember, with Ubuntu, the right package is
apt-get install icedtea6-plugin
At least, on my computer this (or one of its dependencies) makes plot3d 
work on Firefox. (Jaunty and Karmic)

Hope that helps
have a good night

Jmol comes with Sage, so Jmol is always installed.  However, you need
Java to run Jmol.
Sage doesn't fallback to anything if Jmol doesn't work (I wish Sage
did fallback).

That's interesting: I've had problems where it didn't work and I had
to install Jmol myself. Is this a recent change?

No.   The first time Sage made any use of jmol, Sage also included it.
I'm guessing that when you installed jmol your package manager installed
some dependency of jmol (e.g. java), which made Sage's copy of jmol work.
