makVrv::DtIndirectSwitchManager Class Reference
vrvOsg

handles the switches for all the indirect geometry. Sets up the default state of osg::Switch, osgSim::MultiSwitch, and DtDynamicTerrainSwitchNode. Connects to a signal for the DtDynamicTerrainSwitchNode so it can update the indirect buffer when a switch changes. saves off the node path hash for every switch path that is added. Owned by a DtIndirectGeometry 1:1 This manager's switches get updated per frame via looking at the actual switches/multi-switches
