#include <SortedFragmentIterator.hpp>

List of all members.

Classes

• struct SpatialFragment

Public Member Functions

• SortedFragmentIterator (const VCamera &Cam, const RefPtr< Field > &Crds)
• int emitFragments ()

  Iterate over all currently stored field fragments.
  

• virtual bool apply (const SpatialFragment &VF)=0

  The virtual apply function, which would perform some rendering of the current spatial fragment.
  

• void emit (const RefPtr< Field > &theField)

  Emit over the fragments of the field and call the virtual apply() function for each fragment, ordered back to front as seen from the camera.

• typedef multimap< double,
  SpatialFragment > FragmentMap_t

Protected Member Functions

• override bool apply (const RefPtr< FragmentID > &fid, const RefPtr< CreativeArrayBase > &DataCreator)

  The fragment iterator's callback function, used to determine the spatial location of the fragment and collect them in the FragmentMap.
