Right off the bat it sounds like you should be using Tcl Blend.
You can still use you old commands implemented in C/C++ with
new commands implemented in Java.

You know that Java3d just uses OpenGL under the covers right? Java3D is
just another API on top of OpenGL, but I am sure ToGL would be faster.
To sort of answer your question, Tcl Blend 1.2 works with Tcl 8.0, 8.1,
and 8.2, as well as JDK 1.1 or JDK 1.2.

I am still not sure how you are going to do the abstraction so that
your routines can draw to both a Java and C based widget, but
if you can work around that then you should be able to use your
methods with either implementation. As long as your drawing
routines are not actually written in Tcl, you should be able to
use Tcl or Jacl to run the code. I am assuming that your drawing
routines are going to be written in C/C++ or Java for speeds sake.

I have used the tcljava API to create a set of wrapper methods around
the Java Media Framework, so I know for a fact that it is possible.
You can even make it work with both Jacl and Tcl Blend if your extension
is made up of Tcl + Java code only (no C or C++).

This is a feature that people keep talking about but nobody seems
to want to put work into it. It should not be too hard, but getting
the two event loops working together might be kind of tricky.
Currently, there is no support for Tk + Java widgets in the same
toplevel window.
I hope that helps
