wxNVIZ: error if no raster map selected

Reported by:	hamish	Owned by:	grass-dev@…

Description

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)

traceback from wxgui module output window:

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

Hi,

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:

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 MarkusN experienced too, that list will only show raster maps already listed in the current Map Display's layer listing.

Once I've gone back and added it to the layer list it appears, but I can't edit its attributes-- changing the fine and coarse resolution had no effect. (could the fine resolution be made a little bit (~20-30%) finer by default?)

and then if I manually go to the Data tab -> Vector controls and tick the box to have it render on the newly selected raster map, it stays at z=0 below. "Height above surface" there also appears to work as a multiplier, not in map units? but of what? the archsites map is not 3D. the cat number? interesting raindrop effect, but not so good for accurate alignment.

thanks, Hamish

ps- Perspective still needs a hard upper-bound at 180 degrees. 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.

It displays now boundaries by default, centroids can be activated too (r56495, r56497).

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.

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

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:

please test r56500

still happens.

grass7, start g.gui, add roads vector map, go to 3d mode:

Hi,

here's a traceback if I load a raster then a vector-areas map in 2D mode, switch to 3D mode, then change the order of the two in the layer list in the Map Layers tab by dragging the vector map to the bottom of the list:

please try r56551

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 <fields7@grass7> loaded (261 features)
Vector map <arch_pts@grass7> loaded (24 points)
No features from vector map <arch_pts@grass7> fall within
current region
Error loading vector map <arch_pts@grass7>
Loading vector map <arch_pts@grass7> (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

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).
