Re: [osg-users] Getting animations initial frame bones matrix
In skeleton there are bones hierarchy, for each bone which have
osgAnimaion::UpdateBone callback, you can get StackedTransform from it
Now from StackedTransform you can get bone matrix, or StackedTransformElements
(StackedTransform is a vector of those) which represent
scale\translate\rotateAxis\quat\etc transforms of bone.
When your animation not playing, values mentioned above will contain default
bone position in skeleton.
Cheers,
Sergey.

Hi,
I managed to see the information I need debugint the proyect in visual
studio, but I don't know how to reach it ..
Code:
for(int
i=0;i\_AnimationManager-getOSGManager()-getAnimationList().size();i++){
osg::ref_ptrosgAnimation::Animation anim =
_AnimationManager-getOSGManager()-getAnimationList()[i];
if(!anim-getName().compare(name)){
osgAnimation::ChannelList channelList = anim-getChannels();
for(int j=0;j\ channelList.size();j++)
{
osgAnimation::Channel* channel = channelList[j];
osgAnimation::TemplateTarget osgAnimation::Target* target =
channelList[j]-getTarget();
}
}
}
- target
- osgAnimation::Target
+ osg::Reference
_Weight
_priorityWeight
_lastPriority
- _Target
- osgAnimation::TemplateTargetosg::Vec3f*
+ osgAnimation::Target
- _target
+ _v
+ osg::Reference
_Weight
_priorityWeight
_lastPriority
I don't know how to reach _v!
Any suggestion???!!!
Thank you!
Cheers,
Aitor

Re: [osg-users] How to prevent resize of viewer window (Windows and Linux)

I'll stop pestering this thread now and do it the long way. You should be able to do the cross platform route, but if there is a bug on the OSG side on one particular platform we as a community just need to fix it. I just have access to Linux, and have very little Windows experience so can't help out with debugging the Windows side, so have to rely on Windows dev to get things working perfectly under Windows - this normally works out pretty well. To resolve the issue the best route would be to create a small example that illustrates the problem so that others can reproduce, confirm the problem and then work to fix it. Modifying an existing osg example would probably be a good place to start.

I have just checked in some fixes for GLES2 in osgText so it would be worth doing an update to latest svn/trunk for your own work.

I think you misunderstood me. What I meant was that OSG should be able to provide the ability to disable resizing in a cross-platform way (because all of the underlying platforms support it). If it's not doing that properly, then something needs fixing. If you can create a simple example, like Robert suggested, I can try to help with the Linux and Windows implementations. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Getting animations initial frame bones matrix
Sorry, for some reason i thought that u need base skeleton position. For first frame bone positions you can get it from channels. Each channel have name and target name, target name is the bone name which it modifies, channel name is StackedElement name inside of UpdateBone callback. So you stop all animations, then for each animation you do next steps: 1) for each bone you check what StackedElements it have in UpdateBone callback 2) for each StackedElement you look channel in current animation, which have target name same as bone name, and channel name same as StackedElement name if such channel exist you take first keypoint out of it if there are no such channel you take value from StackedElement 3) processed all StackedElements - make matrix from values you've got 4) get next bone and go from 2) 5) all bones processed - get next animation and go from 1) May be there are easier way, but i dont know any. Also idk in what reference frame you need bone matrices. But you can convert these to whatever reference frame if there are such need.

Re: [osg-users] Effect Durations
that seems not work, even i set endless true but the animation soon ends. so does the duration is effectless, or i'm making a mistake on my implementation... -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=45752#45752 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

It looks like the MWM property for resizing is being set correctly, just the window manager (Metacity, in my case) is ignoring it. I'm putting together a submission that uses the ICCCM hints instead. --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
