Detailed Description

FlattenStaticTransformsDuplicatingSharedSubgraphsVisitor is similar to FlattenStaticTransformsVisitor in that it is designed to remove static transforms from the scene graph, pushing down the transforms to the geometry leaves of the scene graph, but with the difference that any subgraphs that are shared between different transforms are duplicated and flattened individually. This results in more static transforms being removed, but also means that more data is generated, and as a result may not always be the most appropriate flatten visitor to use.

◆ reset()

virtual void osgUtil::Optimizer::FlattenStaticTransformsDuplicatingSharedSubgraphsVisitor::reset ( )
virtual

Method to call to reset visitor. Useful if your visitor accumulates state during a traversal, and you plan to reuse the visitor. To flush that state for the next traversal: call reset() prior to each traversal.
