[GRASS-dev] Replacement of NVIZ

Even though I am not a real developer, I just want to say that NVIZ
rocks! It could have some other features (like, create a view with a
oberserver at XXX YYY ZZZ looking to 275 deg north, or something) but
it's easy to use, and produce some really nice outputs. I just
submitted a paper comparing ArcGis and GRASS for morphometric analysis
(guess who won?) and the 3D image we use was made in NVIZ, because
ArcScene doesn't even get close to the beauty of NVIZ 3D image.

Having a [lightweighted] n-D visualizer integrated in the system
really makes a difference.

just my 0.02
