You're correct. You can use Tk widgets in conjunction with VPython, but
currently there is no VPython drawing area that lives inside a Tk widget.
Right now you can basically get a VPython window and a separate Tk window.

In theory this is correctable -- currently we use GtkGLArea on Unix-based
systems, which is a GL context wrapped in a Gtk widget. In theory if a
similar GL widget for Tk exists, you could probably write a new VPython
context to support it without too much difficulty.

In general I think we've found the current level of interaction to be
sufficient. Look through the demos and you'll see some examples of use of
VPython constructs for basic UI elements (colorsliders.py), which may be
sufficient for your purposes.

We used to use PyOpenGL when we were developing VPython -- it was easier for
prototyping. The current setup is much faster, however, which is why Scherer
rewrote VPython in its current form after we had hashed out the basic
interfaces we wanted.
