There was a problem converting a file to Collada by using osgconv like this:
osgconv file.osg file.dae
You would get an error message:
I/O error : Permission denied
I/O error : Permission denied
error : xmlNewTextWriterFilename : out of memory!
Error: daeLIBXMLPlugin::write(file://cessna.dae) failed
Warning: Error in writing to "cessna.dae".
This was due to some bad URI processing code in the Collada plugin. The attached file fixes this by using the Collada DOM's URI processing functions. After this change the file will convert successfully in the local directory.

It might seem odd that the change actually removes the stub apply(Billboard&) method, but it turns out Billboards are easily supported in subordinate routines of the existing apply(Geode&) method with s dynamic_cast, so there's no need for a separate apply(Billboard&)."
avoid threading issues associated with compile running in a parallel with
update/cull on the first frame.
Also added automatic recompile when a new SceneData is applied to a View.
get an excess Tab key report when switching back to an OSG
application (usually FlightGear :-). Although KDE has consumed
the Tab, it's sometimes still in the XKeymapEvent's key_vector,
and followed by a Tab KeyRelease event.
Avoid this artifact by
- asking for a "fresh" keymap (via XQueryKeymap()), rather than
using the unreliable(?) XKeymapEvent's key_vector, and by
- flushing all key events on focus-in (to avoid the KeyRelease)
After Super-press, Tab-press, Super-release, Tab-release (note
the wrong release order!) I still get an extra Tab event. But
this is not surprising and not exactly wrong either. Also it's
hard to avoid, as we can't see what happened to the keyboard
before we regained focus.
Files changed:
src/osgViewer/GraphicsWindowX11.cpp
include/osgViewer/api/X11/GraphicsWindowX11"
I've spotted huge memory leaks int ShapeParser and fixed them.
Also, there was a missing destructor (PolygonM) and a missing member initialization (PolygonZ)
Would be nice if someone could test the changes.
To release the memory just if no reading error happened (and therefore the arrays would be valid) I've added an macro to release and reset the pointers at once. I'm not using macros myself very often as I don't like them, but I think it doesn't hurt in this code.

In essence, the FLT exporter was emitting a full set of Mesh records each time it encountered a PrimitiveSet.
Attached is a fix. The code now emits the Mesh set up records, then iterates over all PrimitiveSets and emits a Mesh Primitive record per PrimitiveSet.
It also loops over PrimitiveSets twice, first writing Face records according to the mode, the writing Mesh records (again according to the mode).
The final change included here is support for GL_POINTS as single-vertex Face records.
Billboards are still to come."
It's implemented in the same way that 3D Spherical Display and Panoramic Spherical Display.
You can test it running:
osgviewer --wowvx-20 cow.osg
osgviewer --wowvx-42 cow.osg
depending on the size of your Philips WOWvx display (20" or 42")
Other arguments you can use to control the 3D effect are:
--wow-content <value>
This value defines the kind of content that can be:
0: No depth
1: Signage
2: Movie
3: CGI
4: Still
--wow-factor <value>
Percentage of the display recommended depth value. Default 64, Range [0-255]
--wow-offset <value>
Amount of range behind the screen. Default 128, Range [0-255]
0: Range is shifted in the direction of the viewer.
128: Range is equally divided in front and behind the screen.
255: Range is shifted away from the viewer.
