Hi,
I've tried the following and it seems to solve my problem :
Code:
void IntersectionVisitor::apply(osg::Group& group)
{
if (!enter(group)) return;
osg::Viewport* pViewport = NULL;
if (group.getStateSet() != NULL)
{
pViewport =
dynamic_cast<osg::Viewport*>(group.getStateSet()->getAttribute(osg::StateAttribute::VIEWPORT));
}
if (pViewport != NULL)
{
pushWindowMatrix(pViewport);
push_clone();
traverse(group);
pop_clone();
popWindowMatrix();
}
else
{
traverse(group);
}
leave();
}
This modification was just a test, but I wonder if this should not be in every
"apply" method of IntersectionVisitor, maybe with these modifications :
- take care of the override value (do not push window matrix if the attribute
is overriden)
- push the window matrix and the intersector clone BEFORE the "enter" test to
ensure the "enter" test is done with correct coordinates frame
Or am I wrong with that and I've missed something ?
Thanks.
