3D Plot fails
bjs
u, v = var('u,v')
fx = u*v
fy = u
fz = v^2
P = parametric_plot3d([fx, fy, fz], (u, -1, 1), (v, -1, 1),
frame=False, color="yellow")
show(P)
I get the error message:
You do not have Java applets enabled in your web browser, or your
browser is blocking this applet.
Check the warning message from your browser and/or enable Java applets
in
your web browser preferences, or install the Java Runtime Environment
from www.java.com
I'm using Firefox 3.0.1 and have Java and Javascript enabled in
preferences. I have Sun Java 6 Runtime installed and I am running sage
3.0.5 under Ubuntu 8.04.
Can anyone suggest what I am missing?

I have no clue.
Just one comment -- if you do
show(P, viewer='tachyon')
at least you'll see a 3d plot, though you can't dynamically rotate it...

firefox 3.0.1 and all java stuff turned on. There is no "warning
message from your browser" that I can see.

I wouldn't be surprised if it's a Firefox 3 security issue. Did you
get any messages about certificates? Did you ever click "accept
once?" Of course it could be something totally different.

and I have not accepted any certificates lately. Is there a simple way
of checking that Java is working in firefox? I'm thinking of a
possible install script error re paths or something of that nature.

Google for "example applet" I'm sure that will turn up an example you
could try.
bjs
which reports that my jre is not running so this is a java/firefox/
Ubuntu problem not a sage problem. I have posted a question on the
Ubuntu support site and I will post again if and when I find a
solution since I am not the only one with the problem. But thanks
again

You probably have sun-java5-jdk, etc. If you want to try openjdk, type
sudo apt-cache search openjdk
and it should tell you which deb files to install using
sudo apt-get install ...

I just installed that (earlier I installed the sun one but it didn't
work in firefox). But -- after restarting firefox -- it still doesn't
work.
David, is your firefox this one:
Gecko/2008072820 Firefox/3.0.1 ?

Yes:
Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.1) Gecko/2008072820
Firefox/3.0.1
I should have added though, I almost always only use the command line.
I just now tried this with the notebook and just got a grey box with
no plot below the cell with the
plot 3d commands.

OK, so that's consistent. I can also display things like
show(sage.plot.plot3d.shapes.Torus(3,1), figsize=6, aspect_ratio=[1,1,1])
from the command line but not the notebook.
