<HTML><FONT FACE=arial,helvetica><FONT SIZE=2>In the Visualization Toolkit 2nd Edition book I see that in plate 62 regarding the Computational fluid dynamics visualization there are shadows. I would like to know how this is done.<BR>
<BR>
On on one of our projects we are working on animating a tower crane sitting on a 2D in 3D surface where we would like the entire assembly to have shadows on the ground -- as we turn the crane. This can be done of course with raw calculations, but since we are rendering within each animation, we don't want to extensive calculations to effect significantly the speed or rotation.<BR>
<BR>
Any ideas are appreciated. I suspect that this is either a trivial problem or extremely complex.<BR>
