class OSGUTIL_EXPORT osgUtil::Optimizer

Insert impostor nodes into scene graph.

Public Methods

Optimizer()

virtual void optimize(osg::Node* node, unsigned int options = ALL_OPTIMIZATIONS)

traverse the node and its subgraph with a series of optimization visitors, specificied by the OptizationOptions

Public Members

enum OptimizationOptions

class OSGUTIL_EXPORT FlattenStaticTransformsVisitor: public osg::NodeVisitor

Flatten Static Trasform nodes by applying their transform to the geometry on the leaves of the scene graph, then removing the now redundent transforms

class OSGUTIL_EXPORT RemoveRedundentNodesVisitor: public osg::NodeVisitor

Remove rendundent nodes, such as groups with one single child

class OSGUTIL_EXPORT CombineLODsVisitor: public osg::NodeVisitor

Optimize the LOD groups, by combining adjacent LOD's which have complementary ranges

class OSGUTIL_EXPORT StateVisitor: public osg::NodeVisitor

Optimize State in the scene graph by removing duplicate state, replacing it with shared instances, both for StateAttributes, and whole StateSets
