Hi Richard, The CullVisitor is the one that does the culling, you can write your own visitor to do this too.
As I said before you can using a drawable or node cull callback to determine visibility on each frame without being overly elaborate. Otherwsie you'll need to use your own custom NodeVisitor. Robert. On 5/28/07, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote:
Is it possible to use a certain node visitor that only visit the visible nodes? I need to get access to the drawable that are visible to perform some analysis (from data stored into the drawable) at a specific moment (called from the user interface). What is the difference between the osg::NodeVisitor VisitorType NODE_VISITOR and CULL_VISITOR?
