[vtkusers] Transparent Textures

[Gregory Neil Kawchuk]

I am fairly new with VTK yet undaunted in trying to make a transparent
texture. 

I am presently using TPlane.tcl as a starting point where a simple texture
is mapped on a 2d object (square).

>From the Schroeder textbook, I realize that the alpha value must be less
than 1, but I can not determine how to do this. I have used the command
SetAlpha .5 for the actor and the transparency without success.

Any suggestions?  Ultimately, I would like to have several unique actors
with their own transparent textures. 

Thanks in advance.
