In general I wouldn't think there would be any speed loss.  Using the
java bindings means that you use java to create a top-level window (a
java Canvas) which is hooked up to VTK by using JNI magic to pass the
window handle to the vtkRenderWindow C++ object.  The graphics
pipeline you create is identical to the one created in a C++ app, so
the rendering should be identical.

The mouse/keyboard event processing goes through java so that might be
different.  Ditto for any callbacks you might have.

This is the private VTK discussion list.
