Hello,
I'm trying to create a remove DOFTransform visitor. I tried this:
void RemoveDofVisitor::apply(osg::Transform& node)
{
if(dynamic_cast<const osgSim::DOFTransform*>(&node)){
osgSim::DOFTransform* pDofNode =
dynamic_cast<osgSim::DOFTransform*>(&node);
if ( pDofNode->getNumParents() > 0 ){
osg::Group* parent = pDofNode->getParent(0);
for( unsigned int i=0; i<pDofNode->getNumChildren(); i++ ){
//TODO make this work for multiple parents.
//Set grandparent of dofs children its parents.
parent->addChild(pDofNode->getChild(i));
}
//Remove children from DOF
pDofNode->removeChild(0, pDofNode->getNumChildren());
//Remove dof from tree
parent->removeChild(pDofNode);
apply((osg::Node&)*parent);
}
}else{
apply((osg::Node&)node);
}
}
But, it crashes. Should this first be done by collecting DOFs with a
visitor, and then removing them from the scene graph? Or would it be safer
to replace the DOFTransform with an osg::Group?
Thanks.
Zach
