Hi Robert,
Hi Sebastian,
The osg::GraphicsContext has a list of Operations that it runs on each
frame, so just add your Operation to the GraphicsContext via from
(include/osg/GraphicsContext header):
/** Add operation to end of OperationQueue.*/
void add(Operation* operation);
This list is run after the Camera's assigned to the GraphicsContext.
See the GraphicsContext::runOperations() method in
src/osg/GraphicsContext.cpp.
The other approach is to assign a Camera to the GraphicsContext that
has a subgraph that contains the operations you want to call. The
advantage with this approach is that the Camera's are all sorted
according to their RenderOrder and RenderNumber, so you can control
render order.
That is exactly what I was looking for.
Thanks a lot.
Cheers
Sebastian
