I've done this before, several times, but now I can't see where the
problem is.
What I want is simply to get the modelviewmatrix from the cullvisitor. But
it returns the identity matrix.
The viewpoint and modelviewmatrix are unchanged even if I move the camera
around.
// Attach callback
geode->setCullCallback(new MyCullCallback());
class MyCullCallback : public osg::NodeCallback
{
public:
MyCullCallback()
: osg::NodeCallback()
{
}
void operator () (osg::Node* node, osg::NodeVisitor* nv)
{
osgUtil::CullVisitor* cv = dynamic_cast<osgUtil::CullVisitor*>(nv);
if(cv)
{
cv->getModelViewMatrix(); // Returns identity matrix.
cv->getViewPoint(); // Returns (0,0,0)
}
...
Is not this the way to do it? What am I missing?
