#128: NVIZ fails to load vector points without other map
----------------------+-----------------------------------------------------
Reporter: neteler | Owner: grass-dev at lists.osgeo.org
Type: defect | Status: new
Priority: major | Milestone: 6.4.0
Component: default | Version: svn-trunk
Resolution: | Keywords: nviz

Comment (by hamish):
FWIW, I've been able to plot a vector map in NVIZ which had 1 million
faces*, it took some time to render but it worked ok.
* NYC 3D buildings dataset
(but points are treated differently than lines and faces in NVIZ)
see also bug #49: NVIZ displays points (sites) always as thematic
In the past I was able to plot 3D points, but created a new constant
surface (so no mapname) from the raster panel and set transparency for it
to 100%; a trick I'm sure you know. screenshot:

does it work for you with fewer points or does it work with a surface
(constant or raster map)? [what do you mean by "without other map"?]
{{{
Error in startup script: can't use non-numeric floating-point value as
operand of "*"
while executing

hmmm,
