For the record - it was my mistake - I did not realize that I had my z-values were stored as attribute. When I changed it to z-coordinate it came out quite nice (the first is from contour points, the second from random points in nc_spm_08) http://skagit.meas.ncsu.edu/~helena/grasswork/TINgrassnviz2.jpg http://skagit.meas.ncsu.edu/~helena/grasswork/TINgrassnvizrand2.jpg - maybe a hint in the man page would help. The only problem that I had in GRASS65 was that nviz kept crashing when I tried to run it with the vector data only so I had to add raster map as a reference plane.
