I just installed FreeWRL and looked at this. Awesome! It looks like
this might be the best way to get good opengl graphics (and mayavi!) in
the sage notebook while we still wait on the possibility of an html
canvas3d tag.
I noticed that, at least with Freewrl, there didn't seem to be an easy
way of rotating the object in the above demo. Instead, all the methods
focused on navigating the camera. Does anyone know a way to rotate the
whole scene around some point, similar to grabbing and dragging an
object in jmol or mayavi? This could be accomplished by moving the
camera around a sphere, always pointing at the same spot in space.
Thanks,
Jason
