Hi, I'm looking at a way to determine if a node is visible (in the frustum) or not.
I saw something about cullvisitor and isCulled() But, I do not understand how to implement that visitor. I saw a osg::Drawable::cullcallback ... Do I have to make my callbak ingerit from this class ? What operator do I have to define (operator()(node*, nodevisitor*) ) ? thanks a lot. Regards, Vincent.
