Hi lucie,
you do something like this
class CollectMatrixTransformNodeVisitor : public osg::NodeVisitor
{
public:
CollectMatrixTransformNodeVisitor() :
osg::NodeVisitor(osg::NodeVisitor::TRAVERSE_ALL_CHILDREN) {}
virtual void apply(osg::MatrixTransform& node)
{
matrixTransforms.push_back(&node);
}
std::vector<osg::MatrixTransform*> matrixTransforms;
};
then
CollectMatrixTransformNodeVisitor nv;
root->accept(nv);
nv.matrixTransforms vector should have all your MatrixTransforms
