Hello and thank you for any help in advance,
I am working with some code that a coworker had created, but is unavailable at
the moment. It deals with Occlusion Query Nodes.
When we were still in OSG version 2.8, my coworker had grabbed a lot of the
methods from the 3.0 version's OcclusionQueryNode.cpp and put them in our code
so that we could use them for our sun. However, now that we have transitioned
to 3.0, the code that was brought in isn't being used anymore, defaulting to
OSG's code.
The issue is, whenever our sun is on screen, we are getting the following error
now: "osgOQ: QG: Invalid RQCB."
This apparenlty happens becaues of this area of code:
Code:
RetrieveQueriesCallback* rqcb = dynamic_cast<
RetrieveQueriesCallback* >( cam->getPostDrawCallback() );
if (!rqcb)
{
OSG_FATAL << "osgOQ: QG: Invalid RQCB." << std::endl;
return;
}
I think it might be that we aren't setting up the nodes correctly, but I
haven't been able to find any examples or documentation related to this error
or how to properly set up occlusion query nodes in OSG.
Any help is appreciated, please let me know if you have any questions regarding
my question.
