Hi Dirk,
Thanks so much for the patch! I got the dailybuild from 04 Dec 05, and
there is
an improvement - at least now I get a window rendered, with the VR Juggler
avatar, in release versions! However, as soon as the volume object comes in
sight (it is by default a little off, so the avatar has to be moved a little
back until it starts being rendered) it crashes again.
I took some screenshots as well, to hopefully explain my problem
better. I also
tried to move makeVolume so it's a class method, so now everything is in
OpenSGNav.cpp. Also, I should node that I have made the volume node to be a
child of the torus node - if this line mModelRoot->addChild(cModelRoot); is
commented, torus is rendered no problem. Here is the source
http://www.smilen.net/VolrenJuggler/Volren04JugglerSend.zip
So, in debug version, it crashes at a white screen:
http://www.smilen.net/VolrenJuggler/Volren04Juggler_crash_dbg.png
resulting with the following window trace
http://www.smilen.net/VolrenJuggler/windowTrace04_debug.txt
and the stack trace
http://www.smilen.net/VolrenJuggler/stacktrace04_debug.TXT
For debug, I get the message WARNING: TextureChunk::initialize: 3D
textures not
supported for this window! which is the same that I get when I run
simpleVolumeNodeRender in Debug mode (Release versions do not have this
problem) - So I ran some tests on the regular VolRen examples and
included them
below.
In any case, the stack trace in debug mode shows the crash at exactly the same
point FieldContainerPtrBase+0x29, though now, for instance
osg::Slicer::getSlicingDirection shows up in the trace.
The same program, in release version, crashes only when the volume comes into
the scene:
http://www.smilen.net/VolrenJuggler/Volren04Juggler_crash_rel.png
resulting with the following window trace
http://www.smilen.net/VolrenJuggler/windowTrace04_release.txt
and the stack trace (having of course only one line, no symbols - so I
cant get
any more information from this) says it crashes at
OSGSystem!osg::FieldContainerPtr::FieldContainerPtr+0x6:
http://www.smilen.net/VolrenJuggler/stacktrace04_release.TXT
As the tests from the regular VolRen examples below will show, using the
DVRSimpleShader in debug mode results with TextureChunk::initialize: 3D
textures not supported for this window! so, as I ran these tests, I figured
that DVRMtexLUTShader works fine for me in debug mode (although it
takes like 4
seconds to render a frame), so I tried to make a version that uses this
shader,
in hope to skip the crash, but still the same. The source is here:
http://www.smilen.net/VolrenJuggler/Volren05JugglerSend.zip
It behaves the same as the Volren04Juggler, so the same screenshots from above
are valid, and the traces are here:
http://www.smilen.net/VolrenJuggler/windowTrace05_debug.txt
http://www.smilen.net/VolrenJuggler/stacktrace05_debug.TXT
http://www.smilen.net/VolrenJuggler/windowTrace05_release.txt
http://www.smilen.net/VolrenJuggler/stacktrace05_release.TXT
Just a wild guess - maybe in a VR Juggler context, it is not obvious to the
rendering system which way the slices should be oriented - since for instance,
they would have to be oriented differently if say you have to render for 6
screens (the slice orientation should change?) - although here I use the
standalone.jconf so I render for only one screen??
Well, it started going somewhere, but not there yet - so hope I will get some
more help to make this example work :)
Immense thanks
smilen
