[GRASS-user] NVIZ can't allocate enough memory

[Daniel Lee]

Hi list,

I'm having some trouble using NVIZ. It's worked before using similar data,
so I'm not quite sure what the problem is. My goal is to overlay aerial
photos over a digital surface model, but I always get errors that GRASS
can't allocate enough memory. It doesn't matter how small I make the
region. The same problem occurs when I try to do that without the aerial
photos, or if I try to take e.g. the red band from the photo and use it as
height without putting a photo on top of it. Here's the error:

(Mon Jun 11 10:54:34

nviz elevation=dom_complete at PERMANENT

ERROR: G_malloc: unable to allocate 18446744071974792324 bytes at gsds.c:575
(Mon Jun 11 10:54:34 2012) Command finished (0
sec)

Does anybody know what could be the problem? If I'm interpreting the bytes
correctly, that'd be about 10^10 gigabytes, which several orders of
magnitude larger than the rasters involved. Thanks!

Best,
Daniel
