[GRASS-dev] d.nviz problem or question

[Michael Barton]

I've pretty much finished a TclTk wrapper for d.nviz. Now I've encountered a
problem running it. In order to do this, I need to use TclTk to grab
coordinate points (x,y pairs) for the route that d.nviz will use. These
should go into the route= option. d.nviz is then run non-interactively to
generate the script for NVIZ.

However, when I try to run  d.nviz with coordinate points, rather than
running it interactively, I get the following errors. Note that this was run
with the Spearfish elevation.dem raster with the region set to the map. The
coordinate points ARE within the map region. I tried this with a much
smaller layback distance and had the same result.

d.nviz complete. Created NVIZ script <fly2.nvscr>.

The script produced does nothing because there are no coordinate points. If
I do this interactively in an xterm, it works fine with exactly the same
parameters.

Any suggestions?
