[vtkusers] The shadow of a vtkPlaneSource

[Junkichi Sugita]

Hi,

A smaller plane is placed over a larger one with a slight tilt, both 
generated by vtkPlaneSource. A light is placed even higher than the 
samller plane, hoping to see whose shadow on the larger plane.
Actually I could not observe any shadow.

I am wondering if VTK can be used to simulate a moire pattern.

Thanks for any suggestions.
