[vtkusers] VTK in a MultiTouch Environment

Yes, it is a PyMT object. You use it like this:

 >>> with fboobject:
 >>>     do_the_drawing()

What this does is bind the FBO (which is an OpenGL Framebuffer),  
execute all the drawing code in the with-block and then unbind it  
again. You can then access the things you drew via the fboobject.
It has a color buffer and a depth buffer.

See this: http://github.com/tito/pymt/blob/master/pymt/graphx/fbo.py

I sincerely hope there is, but I will need your help to find it.

I may be wrong here, but I think one of the problems we were unable to  
solve was actually *getting* the string that contains the address of  
the HIView.

That would be great.

In the hope that my explanation was correct and understandable,
