Hi all, I don't think I have seen this issue addressed in the past (sorry if it has already been addressed), but it is a long time problem with nviz. Whenever I bring my height down below my highest surface elevation, my image flips upside down. I can see the underside of my surface correctly, it is just that I am viewing a mirror image of my surface, reflected on a horizontal plane. Once I adjust my height back higher, the image reverts back to its regular orientation. I have experienced this bug since Grass 5.0, and am now using GRASS 6.1cvs. It usually isn't a problem, however if one has multiple sub-parallel surfaces, it is difficult to view the lower surfaces.
Has anyone else experienced this? Is it just too complicated a bug to fix? Does it only happen on macs?
Thanks, Ian

For sure not only, I've been having it on different Linuces as well.
Annoying, I admit. Hopefully Bob can take a look at this. He's done a
loot of good things for NVIZ.

I've been observing this behavior for years (since the early betas of
5.0.0), and I believe it has been commented on in this list often. I
think if someone figures out why it happens they will earn the undying
gratitude of many NVIZ users. Or at least one.
