Hello,
I am currently trying to write a visualisation routine for magnetic field
lines around a pulsar. The problem is set up in such a way that one
obtains an infinite number of lines which together form a surface. My code
integrates some of these lines and plots them in 3d using the plots
routine. The problem with this procedure is that the surface structure is
often not very clear, which defeats the whole purpose of visualisation as
a tool.
What I really want is to plot the interpolated surface with hidden
surfaces removed. But how?
I though of using shade_volume, but there is no function which is constant
on the magnetic surfaces... What I want is a routine that plots a surface
that can be defined parametrically. I know mathematica can do it, I think
matlab can, but I'm in to idl at the moment, so I would like to stick
with it.
While I'm at it, is there a repository for user contrib code on the
internet that is not in the idl distribution?
Many thanks.
Stephen Hardy
