Detailed Description

template<class T>
class VRS::StateHandler< T >

Class template for state handler.

Author:

Victor Saar The StateHandler is used to collect state information for the class specified through the template argument. It tracks the active state while traversing the scene graph and collects occurring render states and shapes affected by them.

[inline, virtual]

Collect shape for current state.

Implements VRS::AbstractStateHandler.

template<class T>

virtual void VRS::StateHandler< T >::createSortedScene	(	SO< SceneThing >	root,
		SO< Array< unsigned int > >	shapeIndices,
		SO< Array< SO< SharedObj > > >	shapes
	)			[inline, virtual]

Parameters:

	root	Root node of optimized scene.
	shapeIndices	Array with indices for relevant shapes.
	shapes	Array of shapes found in the original scene.

This method is called by the StateSortingOperator on the first state handler in the chain. Each handler takes the given shape indices and computes the relevant indices for each state collected. This is done by creating an intersection between the given array and the indices for the particular render state. If the handler has a successor the intersection array is forwarded to it.

Implements VRS::AbstractStateHandler.
