[GRASS-user] d.nviz problems

I am trying to create a simple fly through animation of the a rendered 3d point cloud using the command d.nviz and am running into issues I hope are first-time user bugs. my g.region is

GRASS 6.4> g.region -p
projection: 0 (x,y)
zone: 0
north: 4134000
south: 3944500
west: 2299000
east: 2714000
nsres: 500
ewres: 500
rows: 379
cols: 830
cells: 314570

I run this

GRASS 6.4> d.nviz -c input=nocars.500.cropped output=nocars.500.animate2 route=[2299000,94750[,2319750,94750[,2340500,94750[,2355000,94750]]]] dist=2 ht=2 frames=10

the output is

WARNING: Skipping this point, selected point is outside region. Perhaps the
camera setback distance puts it beyond the edge?
WARNING: Skipping this point, selected point is outside region. Perhaps the
camera setback distance puts it beyond the edge?

d.nviz complete. Created NVIZ script <nocars.500.animate2.nvscr>.

I then try

nviz el=nocars.500.cropped script=nocars.500.animate2.nvscr

which displays

DONE!
Entering script mode …

The nviz window visualizes my file, but the script never runs.

When I try to manually upload and run the script nothing happens.

I also tried generating a keyframe animation from the d.nviz and it tells me that the file was created, however I cannot locate it or use it. Can anyone help me? I’m just trying to generate a low altitude flythrough of the data.

Thanks
