Detailed Description

An iterator over field fragments that traverses the fragments in back-to-front order as seen from the given Camera.

Member Function Documentation

apply() [1/2]

bool Wizt::SortedFragmentIterator::apply ( const RefPtr< FragmentID > & fid, const RefPtr< CreativeArrayBase > & DataCreator )

overrideprotectedvirtual

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

Implements Fiber::FragmentIterator.

Referenced by emitFragments().

apply() [2/2]

virtual bool Wizt::SortedFragmentIterator::apply ( const SpatialFragment & VF )

pure virtual

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

Implemented in Wizt::Vitreous::FragmentRenderer.
