static void draw (CullableObject *object, GraphicsStateGuardianBase *gsg, bool force, Thread *current_thread)
 Draws the indicated CullableObject, with full support for decals if they are attached to the object.

Detailed Description

This defines the abstract interface for an object that receives Geoms identified by the CullTraverser.

By itself, it's not a particularly useful class; to use it, derive from it and redefine record_object().

Member Function Documentation

void CullHandler::draw ( CullableObject *  object,
GraphicsStateGuardianBase *  gsg,
bool  force,
Thread *  current_thread 
) [inline, static]

Draws the indicated CullableObject, with full support for decals if they are attached to the object.

The appropriate state is set on the GSG before drawing the object.

void CullHandler::end_traverse ( ) [virtual]

This callback function is intended to be overridden by a derived class.

This is called at the end of the traversal.

Reimplemented in PipeOcclusionCullTraverser.

Definition at line 66 of file cullHandler.cxx.

Referenced by CullTraverser::end_traverse().

void CullHandler::record_object ( CullableObject *  object,
const CullTraverser *  traverser 
) [virtual]

This callback function is intended to be overridden by a derived class.

This is called as each Geom is discovered by the CullTraverser.

The CullHandler becomes the owner of the CullableObject pointer and is expected to delete it later.

Reimplemented in BinCullHandler, DrawCullHandler, and PipeOcclusionCullTraverser.

Definition at line 52 of file cullHandler.cxx.

Referenced by CallbackNode::add_for_draw(), GeomNode::add_for_draw(), PlaneNode::cull_callback(), CullTraverser::draw_bounding_volume(), PipeOcclusionCullTraverser::end_traverse(), and NodeCullCallbackData::upcall().
