Re: [osg-users] Loading an osgb file from a statically linked application
Hi, With the following lines added to my code everything works as expected: USE_SERIALIZER_WRAPPER(DefaultUserDataContainer) USE_SERIALIZER_WRAPPER(StringValueObject) Interestingly, these macros aren't used in osgstaticviewer.

Re: [osg-users] play animation backwards?
Hi, I locally changed Animation::update() to be virtual and inherited my own animation class with special backwards animation code in the update() function. Would it be possible to make Animation::update() virtual in future osg releases? Or is my approach rather discouraged? Thank you!

Re: [osg-users] Animation of shared model
Hi Sergey,
Thanks for your advice! Unfortunately I'm not sure if I completely understood
your solution. Would you mind to help me a little bit further?
Suppose I retrieved the model and the animation manager as follows:
osg::ref_ptr osg::Node model = osgDB::readNodeFile(nathan.osg);
osgAnimation::BasicAnimationManager* modelManager = dynamic_cast
osgAnimation::BasicAnimationManager* (model-getUpdateCallback());
Now I add one of several transforms:
osg::ref_ptr osg::PositionAttitudeTransform transform = new
PositionAttitudeTransform();
transform-addChild(model);
transform-addUpdateCallback(modelManager.get());
And finally play all animations of the model:
const osgAnimation::AnimationList animations =
modelManager-getAnimationList();
for (unsigned int i=0; i animations.size(); ++i )
{
modelManager-playAnimation( animations[i].get() );
}
After reading your post I tried not to add the modelManager to the transform
but a new animation manger using the existing animations:
osg::ref_ptr osgAnimation::BasicAnimationManager manager = new
osgAnimation::BasicAnimationManager;
for (unsigned int i = 0; i modelManager-getAnimationList().size(); ++i)
{
osgAnimation::Animation* animation = new
osgAnimation::Animation(*modelManager-getAnimationList()[i]);
// alternatively: osgAnimation::Animation* animation =
modelManager-getAnimationList()[i];
manager-registerAnimation(animation);
}
transform-addUpdateCallback(manager);
But with this approach also all animations off all instances are playing in
parallel. What am I missing?
Thank you!
Cheers,
Thilo

Re: [osg-users] Animation of shared model
Hi Sergey,
I removed the animation manager from the original model:
model-removeUpdateCallback(model-getUpdateCallback());
and created a new animation manager with clones of the original animations:
osg::ref_ptr osgAnimation::BasicAnimationManager manager = new
osgAnimation::BasicAnimationManager;
for (unsigned int i = 0; i modelManager-getAnimationList().size(); ++i)
{
osgAnimation::Animation* animation = dynamic_cast osgAnimation::Animation*
(modelManager-getAnimationList()[i]-clone(osg::CopyOp::DEEP_COPY_ALL));
manager-registerAnimation(animation);
}
transform-addUpdateCallback(manager);
The animations are still played on all instances - even if I add the animation
manager to only the first transform.
Do I have to remove more than just the updateCallback of the original model?
How is it possible that the animation is played on the second instance even if
there is no (animation) updateCallback added to it?
Thank you!
Cheers,
Thilo

[osg-users] Animation of shared model
Hi, I'd like to place several instances of the same model in a scene and play the model's animation individually on each instance - just like having several nathans standing around and letting each one scratch his head asynchronously to the others. The model is loaded once and assigned to a osg::Group. The model's instances are placed by attaching the osg::Group to different PositionAttitudeTransforms. Similar code as in the osganimationviewer is used to retrieve the model's osgAnimation::BasicAnimationManager which is then added as an UpdateCallback for each PositionAttitudeTransform. Obviously, the animations can now only be played synchronously on all instances. How could I achieve being able to start the animation of each instance individually - for example to let each nathan start scratching its head for a few seconds after clicking on it? Thanks a lot for any hints, Cheers, Thilo -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=49274#49274 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Loading an osgb file from a statically linked application
Hi, The simple solution for me was now to let my statically linked application do the conversion from osgt to osgb using simple readNodeFile and writeNodeFile calls. No need to remove useradata containers. The -rdynamic flag isn't necessary, either. Obviously there is a binary incompatibility between two library versions related to the osgb format (The static osg library is build from the OpenSceneGraph-3.0.1.zip archive downloaded from the osg website. The dynamic library version is 3.0.1-4.6 from OpenSuse BuildService.). Does this mean that most probably I'll have to convert all model files again when upgrading the osg library?

Re: [osg-users] play animation backwards?
Hi Paul, Thank your for your suggestion. Decrementing the simulation time in Viewer::frame() would probably allow to play one animation backwards. But I would be stuck if I wanted to play two different animations at the same time, one being played backwards and one in the normal direction?

[osg-users] play animation backwards?
Hi, Unfortunately I couldnt figure out how to play a given animation backwards. The animation is part of a model read from an osgt file. Looking at osgAnimation/Animation.cpp it would be straightforward to add an additional switch case to Animation::update() case ONCE_BACKWARDS: t = _originalDuration - t; if (t 0) return false; However, I wonder if there is an obvious way to achieve the same without having to modify the file Animation.cpp ?

Re: [osg-users] osgviewer crash
Hi Robert, Thank you for your reply! Probably there is a misunderstanding: osgviewer is not killed all the time. It is started once until it crashes by itself. The xterm-script is started in a separate terminal and only opens/closes a single plain xterm. osgviewer runs fine for quite some time while the script opens and closes an xterm on top of the osgviewer fullscreen view. But after a while osgviewer crashes. The script opens and closes an xterm to simulate opening and closing a Settings Window in my application. Once in a while my application crashes after a user opened/closed that window. I found that the same thing happens with osgviewer and xterm. I'm ran osgviewer in SingeThreaded mode. I'd appreciate any further hints, Thanks, Thilo Hi Thilo, This is may well be a driver issue. Killing the app really isn't a good way to test things... you can actually get the OSG to viewer::run() for a limited number of frames then exit using the env var - set OSG_RUN_FRAME_COUNT to something like 10. i.e. export OSG_RUN_FRAME_COUNT=10 osgvewer cow.osg Another route of investigation would be to for the OSG to run single threaded by doing: export OSG_THREADING=SingleThreaded Then running osgviewer/example. Whether this will change the behavior, or whether it'd indicate an OSG threading bug or X11/GL driver bug I wouldn't be able to say. What I can say is really thrashing the X server/GL driver this way is not really testing it in ways that actual users will ever stress your application. Robert.

[osg-users] GraphicsWindow::setWindowDecoration using kde4 and icewm
Hi, Switching osgviewer to windowed mode (using the 'f' key) yields a decorated window using icewm. However, I get a borderless window using kde4. The same happens if I change the window decoration in my own app using osgViewer::GraphicsWindow::setWindowDecoration(). Is there a way to force kde to put borders around the window? Or am I just missing a simple kde setting and should rather post on a kde mailing list?
