#52: NVIZ fails to display all points in a point vector map
-----------------------------------+----------------------------------------
Reporter: tvrusso | Owner: grass-dev@lists.osgeo.org
Type: defect | Status: new
Priority: major | Milestone: 6.4.0
Component: default | Version: unspecified
Keywords: NVIZ, display, points |
-----------------------------------+----------------------------------------
I observed some strange behavior in NVIZ while trying to work through
examples in the 3rd edition of "Open Source GIS: A GRASS GIS Approach" by
Markus Neteler and Helena Mitasova.
To reproduce:
- download the nc_spm_06 GRASS location from http://www.grassbook.org/
under the Data Sets link for 3rd edition
- Start GRASS with that location and run the command given in Chapter
3.1, First Steps, on page 33:
g.region rast=elevation
nviz elev=elevation vect=streams,roadsmajor, point=overpasses
When I run the last command, only a single overpass point is displayed.
See first attached screenshot, where a single red sphere is visible.
However, if I change the region slightly, say by expanding it five meters
in all directions:
I then see all the points as they should have been, as displayed in second
screenshot, where multiple points are visible.
This is with GRASS SVN checked out this morning (and was present in SVN
for at least the last week, probably longer but this is the first time I
checked).

Comment (by tvrusso):
My GRASS commands got munged by the wiki formatting. They looked OK in
the preview, but it should be clear where the line breaks should have
been, separating the g.region and nviz commands.
