<br><font size=2 face="sans-serif">In the Visualization Toolkit (4th Edition,
Page 216) it states:</font>
<br>
<br><font size=2 face="sans-serif">"Besides the different ways in
which a texture map can be defined, there are options in how it interacts
with the original color of the object. A common option for RGB and
RGBA maps is to ignore the original color; that is, just apply the texture
color as specified. Another option is to modulate the original color
by the texture map color (or intensity) to produce the final color."</font>
<br>
<br><font size=2 face="sans-serif">When I apply a texture map to a vtkPolyData
actor, the surface color of the actor bleeds through the texture map. Other
than the book reference above, I can not find any information about how
to control the 'opacity' of a texture map when it is applied to a vtkPolyData--->vtkPolyDataMapper--->vtkActor.
My vtkPolyData object is a terrain map derived from an vtktImageData--->vtkWarp
and the color is set using a vtkColorTransferFunction to map the single
component scalar.</font>

right direction?</font>
