Hi,
from today onwards GRASS 5.1 CVS snapshots are generated
on a weekly basis:
http://grass.itc.it/grass51/
(and mirror sites)
The snapshot contains the new preliminary 3D vector engine
with DBMS support. Probably we can publish some sample
vector data for playing with the new toy.
What's new:
- vector library completely rewritten (multilayer, multiformat, 3D, TIN
support etc.)
- DBMS drivers (DBF and others)
Most work was done by Radim Blazek, congrats to him.
You are kindly invited to try and develop the initial GRASS 5.1.
Please keep in mind that it is highly experimental.
Cheers
Markus Neteler

Simple data package:
http://www.raz-dva.cz/krakonos/g51test-4.tar.gz
Unpack, start grass51, select mapset 'test' and then
you can run for example script 'tour' or 'd.m &'
(Nviz now in repository: script 'tower' and then
'nviz elevation=dem vector=tin,contours,tower')

Everything is working now! A big congratulations from here, Radim!
a) tour
d.m &
b) tower
nviz elevation=dem vector=tin,contours,tower
Just cool!

Hi Radim,
http://grass.itc.it/images/grass51trees.jpg
...this is absolutly great....
Do you know the "fire" demo of Mesa? Probably it's even
possible to add the shade of the trees on ground as openGL
should know how to do it. If I find time I want to
add the openGL fog to NVIZ, should be only a few lines in
libes/ogsf/. Or maybe someone else is better in openGL that
me 
And the filled vector polygons we should keep in mind for NVIZ.
Perhaps we find a volunteer,
Markus

I don't plan any activity in this field. Instead I want to write v.out.pov.
If you want realy good pictures, you must use PovRay anyway.

let me note that OpenGL certainly is a good interface to write
applications like this.

For education of the other readers I want add that
PovRay is a raytracer which work completly different from
most render engines that will fuel OpenGL.
PovRay also is not Free Software.
There are many interesting Free Software 3D renderers
and raytracers around, maybe we can target one of those.
