I▓ve got the following question:
How do I extract the animations from the exported (OSG)file.
The code (FAQ OsgExp for 3DMAX) not work:
What exactly should be changed?
std::vector(osg::PositionAttitudeTransform*) _cameras;
std::vector(osg::Switch*) _switches;
std::vector(osg::AnimationPathCallback*) _animations;
/**
* Find all special nodes in the scenegraph.
*/
void Previewer::findSpecialNodes(osg::Node* node){
// Find animations
if(dynamic_cast(osg::AnimationPathCallback*) (node->getUpdateCallback())){
_animations.push_back(dynamic_cast(osg::AnimationPathCallback*)
(node->getUpdateCallback())->getAnimationPath());
}
// Find cameras
if(dynamic_cast(osg::PositionAttitudeTransform*) (node)){
_cameras.push_back(static_cast(osg::PositionAttitudeTransform*) (node));
}
// Find switches
else if(dynamic_cast(osg::Switch*) (node)){
_switches.push_back(static_cast(osg::Switch*) (node));
}
// Traverse any group node
else if(dynamic_cast(osg::Group*) (node)){
osg::Group* group = static_cast(osg::Group*) (node);
for(unsigned int i=0; igetNumChildren(); i++)
findSpecialNodes(group->getChild(i));
}
}
