Re: [osg-users] Get all vertices of an OSG Group
Hi Clement,
This is rather easy to do. All you need is to define a NodeVisitor and run it
on the group. Using this way you only need to have an accept call for the Geode
and process the drawables under the Geode.
Code:
class InfoVisitor : public osg::NodeVisitor
{
public:
InfoVisitor()
{
setTraversalMode( osg::NodeVisitor::TRAVERSE_ALL_CHILDREN );
}
void apply( osg::Geode& geode )
{
for ( unsigned int i=0; iaccept(visitor);
// After it completes you can retrieve your data structure.
Hope this helps.
Tony V

[osg-users] Get all vertices of an OSG Group
Hi, I have to work on a point cloud which was stored in .osgb files for LOD management reasons. I have extracted it in an osg::Group, then this Group contains other Groups and so on. I need to access every points of my cloud to extract coordinate or colors. I don't know if there is an easy way to do it since these are contained in osg::Drawables that are contained in osg::Geodes. Do you know a simple way to do it ? Or do I have to explorate my first group recursivly in order to get vertices and colors arrays and to copy them in a std::map ? ... Thank you!

Re: [osg-users] Does OSG still build against Qt 4.8.7?
Hi Christian, CORRECTION: in that specific case there is only Qt4 installed on the machine. In this case OSG won't even configure properly. OSG got installed "properly". I mean that the dependent project which I was trying to build didn't configure properly, simply because the libosgqt library wasn't existing.
