Ok! I managed to do it by putting them in a osg:: Switch and calling
morphsGrp-> setAllChildrenOff ();
But I have performance problems ... to manage various morphs I have followed
this model:
Code:
std::vector<osg::ref_ptr<osg::Geometry>> geoms;
morphsGrp = new osg::Switch();
std::vector<osgAnimation::MorphGeometry*> morphGeometrys;
int morphsCont = 0;
for(int i=0;i<animations.size();i++)
{
if(!animations[i].type.compare("animation")){
...
}
else if(!animations[i].type.compare("morph")){
osg::notify(osg::WARN) <<".......reading morph "<<
animations[i].callName << std::endl;
osg::ref_ptr<osg::Node> shape0 =
osgDB::readNodeFile(animations[i].loadDir);
if (!shape0) {
std::cerr << "can't read morphtarget" << std::endl;
}
else{
osg::Geometry* geom =
osgGenerals::findGeometryNode(shape0)->asGeode()->getDrawable(0)->asGeometry();
if(!geom) {
std::cerr << "can't read geometry" << std::endl;
}
else{
geoms.push_back(geom);
osgAnimation::Animation* animation = new
osgAnimation::Animation;
osgAnimation::FloatLinearChannel* channel0 = new
osgAnimation::FloatLinearChannel;
channel0->getOrCreateSampler()->getOrCreateKeyframeContainer()->push_back(osgAnimation::FloatKeyframe(0,0.0));
channel0->getOrCreateSampler()->getOrCreateKeyframeContainer()->push_back(osgAnimation::FloatKeyframe(0.5,1.0));
channel0->getOrCreateSampler()->getOrCreateKeyframeContainer()->push_back(osgAnimation::FloatKeyframe(1.0,0.0));
channel0->setTargetName(animations[i].callName);
channel0->setName("0");
animation->addChannel(channel0);
animation->setName(animations[i].callName);
animation->computeDuration();
animation->setPlayMode(osgAnimation::Animation::ONCE);
m_morphManager->registerAnimation(animation);
// initialize with the first shape
morphGeometrys.push_back(new
osgAnimation::MorphGeometry(*geometryBase));
morphGeometrys[morphsCont]->addMorphTarget(geoms[morphsCont].get());
osg::Geode* geodeMorph = new osg::Geode ;
geodeMorph->setName(animations[i].callName);
geodeMorph->addDrawable( morphGeometrys[morphsCont]) ;
osgAnimation::UpdateMorph* updateMorph = new
osgAnimation::UpdateMorph(animations[i].callName);
geodeMorph->setUpdateCallback(updateMorph) ;
morphsGrp->addChild(geodeMorph);
morphsCont++;
}
}
}
}
osgAnimation::Animation* animation = new osgAnimation::Animation;
osgAnimation::MorphGeometry* morphGeometry = new
osgAnimation::MorphGeometry(*geometryBase);
morphGeometry->addMorphTarget(morphGeometrys[0]);
osgAnimation::FloatLinearChannel* channel0 = new
osgAnimation::FloatLinearChannel;
channel0->getOrCreateSampler()->getOrCreateKeyframeContainer()->push_back(osgAnimation::FloatKeyframe(0,0.0));
channel0->getOrCreateSampler()->getOrCreateKeyframeContainer()->push_back(osgAnimation::FloatKeyframe(0.5,1.0));
channel0->getOrCreateSampler()->getOrCreateKeyframeContainer()->push_back(osgAnimation::FloatKeyframe(1.0,0.0));
channel0->setTargetName("playMorphs");
channel0->setName("0");
animation->addChannel(channel0);
for(int i=0;i<morphGeometrys.size();i++){
morphGeometry->addMorphTarget(morphGeometrys[i]);
osgAnimation::FloatLinearChannel* channel0 = new
osgAnimation::FloatLinearChannel;
channel0->getOrCreateSampler()->getOrCreateKeyframeContainer()->push_back(osgAnimation::FloatKeyframe(0,0.0));
channel0->getOrCreateSampler()->getOrCreateKeyframeContainer()->push_back(osgAnimation::FloatKeyframe(0.5,1.0));
channel0->getOrCreateSampler()->getOrCreateKeyframeContainer()->push_back(osgAnimation::FloatKeyframe(1.0,0.0));
channel0->setTargetName("playMorphs");
channel0->setName("0");
animation->addChannel(channel0);
}
animation->setName("playMorphs");
animation->computeDuration();
animation->setPlayMode(osgAnimation::Animation::ONCE);
m_morphManager->registerAnimation(animation);
osg::Geode* geodeMorph = new osg::Geode ;
geodeMorph->addDrawable( morphGeometry) ;
geodeMorph->setUpdateCallback( new osgAnimation::UpdateMorph("playMorphs") ) ;
morphsGrp->addChild(geodeMorph);
morphsGrp->setAllChildrenOff();
morphsGrp->setUpdateCallback(m_morphManager);
if(morphGeometry){
geom0->setSourceGeometry( morphGeometry);
modelNode->addChild( morphsGrp ) ;
return true;
}
Now I load about 15 morphs and the performance is about 17 frames per second.
Loading 3, the performance goes up twice. Any ideas on how to improve this?
Thank you!
Cheers,
Aitor
