I just tried this, and it turns out that I DO get the same result you do. Also,
trying to view any 3D vector in nviz gives the following error:
Starting 3D view mode...
Loading raster map <elevation@PERMANENT>...
Loading raster map <elevation@PERMANENT>...
Translating colors from raster map <elevation@PERMANENT>...
Vector map <firestations3D@grass7vect_sqlite> loaded (7
points)
No features from vector map
<firestations3D@grass7vect_sqlite> fall within current
region
Error loading vector map <firestations3D@grass7vect_sqlite>
Loading vector map <firestations3D@grass7vect_sqlite> (lines) failed
Unfortunately, your fix does not work for me. Changing /nviz/mapwindow.py at
line 76 to ...
from wx.glcanvas import WX_GL_DEPTH_SIZE
attribs=[WX_GL_DEPTH_SIZE,16,0]
glcanvas.GLCanvas.__init__(self, parent, id, attribList=attribs)
...breaks nviz entirely. Even rasters won't display after this code change.
Here is the error in the console:
glcanvas.GLCanvas.__init__(self, parent, id,
attribList=attribs)
File "/Applications/GRASS/GRASS-7.0.app/Contents/MacOS/etc
/python/wx/glcanvas.py", line 103, in __init__
_glcanvas.GLCanvas_swiginit(self,_glcanvas.new_GLCanvas(*arg
s, **kwargs))
wx._core
.
PyAssertionError
:
C++ assertion "fmt" failed at /BUILD/wxPython-
src-2.8.12.1/src/mac/carbon/glcanvas.cpp(228) in Create():

The terminal window gives a different error:
Exception AttributeError: "'GLWindow' object has no attribute 'timerAnim'" in
<bound method GLWindow.__del__ of <nviz.mapwindow.GLWindow; >> ignored
I'm using GRASS 7 r55179

Anna,
I have not noticed this particular problem on the Mac and I DO use wxPython
2.8.12.
I've noticed a different issue of vector colors, but not this. I will try to
recompile with these changes and see if it makes any difference in anything.
Michael

Hi,
I have recently noticed strange behavior of wxNviz, for example vector
layer is always visible even if I use negative z coordinate and it
should be hidden below a surface. Probably, it is connected to newer
wxPython version I started to use recently (2.8.12, so it's actually
not new at all). According to the discussion [1], I tried these lines:
Index: nviz/mapwindow.py
===================================================================
--- nviz/mapwindow.py (revision 55276)
+++ nviz/mapwindow.py (working copy)
@@ -72,8 +72,10 @@
def __init__(self, parent, id = wx.ID_ANY,
Map = None, tree = None, lmgr = None):
self.parent = parent # MapFrame
- glcanvas.GLCanvas.__init__(self, parent, id)
+ from wx.glcanvas import WX_GL_DEPTH_SIZE
+ attribs=[WX_GL_DEPTH_SIZE,16,0]
+ glcanvas.GLCanvas.__init__(self, parent, id, attribList=attribs)
MapWindow.__init__(self, parent, id,
Map, tree, lmgr)
which solved the problem. So, I would like to know if someone noticed
this problem on other platforms than Linux. It's not clear to me if
these lines are harmless or not for other platforms and if the number
of the WX_GL_DEPTH_SIZE (= 16) can be used safely (probably different
number works on different computers, see also [2]).
Thanks for any info,
Anna
