[vtkusers] Cutting a hole in a texture

[Sara Broughton - CSCI/P2002]

Okay, I know this is a very basic question:

Has anyone been able to cut a hole (via transparency) in a texture plane 
mapped from vtkImageData?? 
 
I'm attempting to use vtkImplicitTextureCoords with vtkBooleanTexture to 
cut a hole in a texture mapped to a vtkTextureMapToPlane object (in 
conjunction with a vtkPlaneSource).  However, once I apply these 
2 filters, the texture from the image data disappears from the 
plane entirely.

I'm sure this can be done... I'd appreciate hearing how you did it.

Thanks very much.
