Detailed Description

Visits all nodes and set the node mask to allow/prevent processing by the other, more costly visitors. Also precomputes the 3D convex hull of nodes that will be processed so that less vertices are used by the other visitors. Sets the values of PendingTransforms

Member Function Documentation

void OptimizerVisitor::apply (  osg::Transform &  transform  )  [virtual]

Method to be called for a transform. It updates the PendingTransform

void OptimizerVisitor::apply (  osg::Group &  group  )  [virtual]

Two optmizations are performed: branches that do not contain any node that depend on the error estimate have their nodeMask set so that they are not visited by either the ErrorVisitor or the AugmentVisitor. Also, a 3D convex hull of the vertices of an object is store on Group and is used by the AugmentVisitor

void OptimizerVisitor::apply (  osg::Geode &  geode  )  [virtual]

Method to be called for a GEODE adds all the vertices on this Geometry to the _vertices vector.
