Hi, iceberg,

  Rhinoceros 3D is my favorite 3D modeler. Its user
interface is very handy.

  glFrustum is an OpenGL API for setting modelview
matrix.

  Yesterday I download a XGL viewer which I think
may be useful for our project:

  I'd recommend you have a try. It's camera/navigation
system is different from ours, although very simple,
but still convenient. I think we can learn something
from it. I think the camera/navigation system of
Rhinoceros 3D is better. You can get a evaluation
version and have some feeling about it:

  As to your suggestion about tree view. I think it's
a good idea. It's convenient to provide a tree view
for the data of a project, including geometries,
excitations, materials, ports, etc.

  Do you plan to implement TShape as polygons? Since
GLMoM can only use triangular mesh, if we use polygons,
we should use a mesh generator to mesh the polygon. This
is not an easy work for arbitrary polygons. I'd like to
suggest you have a look at easy mesh:
http://www-dinma.univ.trieste.it/~nirftc/research/easymesh/

  I plan to use it as our mesh generator, so can you make
your data structure compatible with it? By connect/disconnect
checking do you mean the sharing of edges between two polygons?
If two polygons have common edges, they are connected together,
if they do not have common edges, they are disconnected. Is my
understanding correct?
