To Robert Irie: Fairly high on our priority list is the ability to import
3D models. Ari Heitner in particular has expressed a strong interest in
this. But it won't happen for many months. There is the problem that there
doesn't seem to be a generally accepted data format for 3D models. DXF is
fairly widely used, but it is very defective in what it can represent.
To Larry Martin: The only object with labels at the moment is sphere, and
its label attribute is considered experimental and likely to go away in
favor of a much more generally useful label object which Dave Scherer is
currently debugging. It has the property that you specify a point in world
coordinates, then specify a line in pixel coordinates from there to a box
containing a label, with text whose height is in pixel coordinates. You can
optionally not show the line or the box.
If you say "scene.up = (1,0,0)" a vertical line on the screen now
represents the x axis. There does seem to be something problematic about
making the z axis the up vector. Note too that individual objects have up
attributes.
