Can someone confirm how vtk deals with Shadows?

[david.pont at forestresearch.co.nz]

Renny,
     The OpenGL web pages have some very interesting information about realtime
interactive rendering of shadows (and reflections, etc), complete with example
images and C++ code.

A good place to start is:
      http://www.opengl.org/Coding/Rendering.html

A link at the bottom of that page leads to:
     http://reality.sgi.com/opengl/tips/

And from there is this link, take a look, this is quite impressive:
     http://reality.sgi.com/opengl/tips/rts/

Wouldn't it would be nice to get some of these techniques added to vtk?, even if
only supported on OpenGL.

     cheers
          Dave Pont
