Subject: g3d region problem
Platform: GNU/Linux/i386
grass obtained from: Trento Italy site
grass binary for platform: Compiled from Sources
GRASS Version: 5.7 weekly snapshot: 12-25-04
g3d-files appear to be immune to changes to the current region made by
d.zoom
example: A g3d-file is created from several rasters in a location (including
setting the r3-parameters for g.region). Then the current region is modified
by zooming in using d.zoom.
When NVIZ is now called up, the 2d-region settings are as to be expected,
yet the 3d-volume settings are way up in limbo: strange volumes (from outer
space?) roam the skies.
a workaround is to recreate the g3d-file after each zooming-step.
Cheers,
Peter Loewe |

The problem is in NVIZ or in the module creating the raster 3D?
Can you post the output from?:
g.region -p3
r3.mapcalc "test=1"
r3.info test1

Hey Radim,
the output you requested is in the attachments.
I was further able to track the problem down:
Imagine a 400x400 XY-location
A zoom into the _northeastern_ quadrant displays the correct rasters, yet
the volumes from the
_southeastern quadrant_. I would guess that somethings funny regaring the
Y-coordinate for volumes.
Cheers,
Peter
