new to the list, cgkit newbie, would greatly appreciate help with the folowing:
  1. Importing a 3ds (or dxf, or .skp, not picky) file as a TriMeshGeom object.
  2. Visualizing it,
  3. Accessing the geometry (specifically, to run intersectRay() on it).
I found a 3ds import function (at http://cgkit.sourceforge.net/doc2/node185.html), but have no idea how it works. Would very, very much appreciate an example or walkthrough on the process.
