Detailed Description

This stores the result of a BinCullHandler traversal: an ordered collection of CullBins, each of which holds a number of Geoms and RenderStates to be rendered in some defined order.

This is also used to keep the results of last frame's cull traversal around to make next frame's traversal of the same scene a little easier.

void CullResult::add_object ( CullableObject *  object,
const CullTraverser *  traverser 
)

Adds the indicated CullableObject to the appropriate bin.

The bin becomes the owner of the object pointer, and will eventually delete it.

void CullResult::bin_removed ( int  bin_index) [static]

Intended to be called by CullBinManager::remove_bin(), this informs all the CullResults in the world to remove the indicated bin_index from their cache if it has been cached.

void CullResult::draw ( Thread *  current_thread)

Asks all the bins to draw themselves in the correct order.

void CullResult::finish_cull ( SceneSetup *  scene_setup,
Thread *  current_thread 
)

Called after all the geoms have been added, this indicates that the cull process is finished for this frame and gives the bins a chance to do any post-processing (like sorting) before moving on to draw.

CullBin * CullResult::get_bin ( int  bin_index) [inline]

Returns the CullBin associated with the indicated bin_index, or NULL if the bin_index is invalid.

If there is the first time this bin_index has been requested for this CullResult, creates a new CullBin object on the fly.
