[GRASS-user] nviz: transparency, masks

[Martin du Saire]

Okay, I *thought* I  figured it out...

Here's the situation:
[Cygwin\Grass6.0 on XP]

created an r.buffer which I wanted to use to control transparency of 
dem displayed with nviz.  I have tried one distance, and multiple 
distances.  I have tried r.reclass, but cannot figure out how nviz 
uses the class values to determine if and how each buffer zone is displayed.

Is it possible to use a raster buffer to control transparency in nviz?

How does nviz use the class values to control the degree of 
transparency of the surface color?

How does it treat the "no data" pixels in the buffer?

Thanks.
