 The error is fixed in r56578. However showing centroids is controlled on
 3d view vector page - check load points checkbox

 Some of the default values can be set in 3d view settings.

 these things are quite experimental but the pan button should work (not
 really panning but it changes focus)

 This ticket is fixed (in terms of the initial problem).

Comment(by hamish):

 Hi Anna,

 the two fixes (r56560 and r56551) seem good, thanks.

 more testing...

 adding a vector points map to the 'Map layers' list after there
 is already a vector area map open in 3D mode tries to load a points
 map as a lines map and fails:

 {{{
 Starting 3D view mode...
 Vector map  loaded (261 features)
 Vector map  loaded (24 points)
 No features from vector map  fall within
 current region
 Error loading vector map 
 Loading vector map  (lines) failed
 }}}

 (but then the points render ok anyway and get added to the Data
 vector controls correctly)

 -

 I don't have much interest in displaying centroids, but for the
 sake of testing them, with the vector area and a points map already
 loaded, go back to the Map Layers tab and edit the d.vect preferences
 for the area map to show centroids too:

 {{{

 -

 some other observations & 2c feedback:

 perhaps make the default line width 1; width=2 looks a bit
 "nibbled" (see screenshot), even after raising the height
 above surface by about $nsres distance.

 perhaps make the default line color a little more muted (aqua?)

 perhaps make the default raster fine/coarse resolution 20-30% finer
 and/or perhaps set the default coarse mode back to wire-frame.


 dragging layers around in the Map layers tab while in 3D view mode
 is a bit clunky. afterwards I got a weird mix in the vector roads
 map of some lines as the default blue,size=2 and others the modified
 aqua,size=1 I did before loading the raster layer. (see screenshot)


 you'll also notice in the screenshot a red-trail in the top right.
 that always follows my mouse around, it disappears as soon as I move the
 view-puck. shrug. (open source radeon driver on debian/squeeze)


 rotate 3D mode is highly sensitive to mouse movement. fly-through mode
 next door is very very slow to react. the normal Pan button seems to
 do nothing other than redraw the scene as-is. (maybe have it
 "Look: [here]" ?) hmm, after that fly-through mode no longer works..


 for Animation, perhaps make the default file format PPM instead of TIF,
 as that is what the encoders will generally want as input.
 consider to add a help button to the animation page, with a link to
 the "Movies" grass wiki page for tips on encoding to .avi, .gif, etc.


 thanks,
 Hamish

 currently if you type e.g. `325` degrees in the box and move the slider
 you can see where it crosses over itself and the geometry inverts.
 interesting, but not really usable.

 Hi,

 I tested both of these in trunk, seems ok.


 I also tested adding points without a surface, the first time I again got
 the repeating "Gtk-CRITICAL **: gtk_range_set_range: assertion `min <
 max'" in the terminal, but quitting the gui and restarting it then worked.
 I'll try to test that more later.

 thanks,
 Hamish

 It should be in map units. The problem appears only when there is no
 surface to drape the points on. Should be fixed in r56515.

 it's better for points now, thanks, but still some small tweaks needed
 elsewhere. comments as I go:


 tested Spearfish's bugsites map in devbr6, looked ok. when tested in the
 old 6.4.3svn version only a thin line rendered until I moved the
 z-exaggeration slider off 0.0 to 1.0. (which seems like a nice default)


 fwiw there doesn't seem to be a need to abbreviate exaggeration to exag.
 since there is lots of space to the right of it for the text.


 restarting the GUI in devbr6 and adding Spearfish's roads did not go well,
 nothing rendered, lots of this repeating in the terminal:
  (.:25449): Gtk-CRITICAL **: gtk_range_set_range: assertion `min < max'
 failed

 and endless repeating tracebacks:

 Spearfish geology (area) did not render at all. Perhaps it could check
 'v.info -t' via vector.vector_info_topo() and if a vector map containing
 area features is loaded pop up a warning and offer to render the
 boundaries-as-lines instead?


 Going to the wxNVIZ Data tab at that point and trying to add a raster
 didn't work, the drop down showed the current mapset and PERMANENT, but no
 maps within them and no '>' triangle or so to click to expand them. I
 supposed that's what

 It seems that this is already done. Try r56122 which should fix the

 Hi,

 testing wxNVIZ in latest 6.5svn, I get an error and 100% CPU use if I
 select '3D view' in the map display window with just a vector map
 selected. (also tried with a 3D vector map, same thing) happens both on my
 linux and Wingrass-VM. It's recoverable once you switch back to '2D view'
 mode.

 one possible solution is in the case of no raster tell nviz to create a
 new constant surface at z=0 with 50% transparency. (or at least that's the
 trick with tcl/tk nviz + no raster to drape things on)
