Detailed Description

The DtOsgRenderer is the component responsible for rendering 3D images onto the screen via OpenSceneGraph The component responsible for drawing 3D images onto a screen is the DtRenderer.

Each display engine owns one. The DtRenderer provides an interface for updating the scene graph and rendering the scene. Its update() and render() functions are called each display engine tick.

The core VR-Vantage Toolkit framework abstracts away from the underlying rendering implementation. This separation ensures that the rendering-independent code remains independent of OSG, while the rendering code exists in the libraries that depend on OSG. (VR-Vantage can support alternate rendering solutions.) The DtOsgRenderer is the OSG implementation of the DtRenderer and draws 3D images via OpenSceneGraph.

Under each model set group is another channel group for each visualizer type.

So we have a map of visualizer type groups, one per model set

typedef boost::unordered_map< DtChannel*, ModelSetRootMap > makVrv::DtOsgRenderer::ChannelRootMap

protected

DtChannelSpecificGroup that contains only the channel it represents.

This will allow for osg nodes to be parented on a channel basis under each model set. As an observer changes which model set it is viewing on the channel, the channel will be removed fom the channel specific group, however, the root itself will stay. The only time the root is removed is when the channel itself is destroyed

osg::ref_ptr<osgViewer::Viewer> makVrv::DtOsgRenderer::myDefaultViewer

protected

This viewer exists so that when there are no displays, windows, or channels, the scene can be updated and kept current.

This way when a display, window, channel is created, the objects in the scene graph are current and will match other IG instances. It only gets updated when there myOsgWindowManager is null. It also never renders.
