DisplayRegionDrawCallbackData (CullResult *cull_result, SceneSetup *scene_setup) | |
virtual TypeHandle | force_init_type () |
CullResult * | get_cull_result () const |
Returns a pointer to the CullResult, the list of CullableObjects that should be drawn in this DisplayRegion. | |
SceneSetup * | get_scene_setup () const |
Returns a pointer to the SceneSetup object, which contains information about the camera and such. | |
virtual TypeHandle | get_type () const |
virtual void | output (ostream &out) const |
virtual void | upcall () |
You should make this call during the callback if you want to continue the normal rendering function that would have been done in the absence of a callback. | |

This function is declared non-inline to work around a compiler bug in g++ 2.96. |

static void DisplayRegionDrawCallbackData::init_type | ( | ) | [inline, static] |
This function is declared non-inline to work around a compiler bug in g++ 2.96.
Making it inline seems to cause problems in the optimizer.

void DisplayRegionDrawCallbackData::upcall | ( | ) | [virtual] |
You should make this call during the callback if you want to continue the normal rendering function that would have been done in the absence of a callback.
Specifically, this method will draw all of the objects in the CullResult list that have been built up for the DisplayRegion during the cull traversal.
