TGLScene Class Reference

TGLScene provides management and rendering of ROOT's default 3D /object representation as logical and physical shapes.

A GL scene is the container for all the viewable objects (shapes) loaded into the viewer. It consists of two main stl::maps containing the TGLLogicalShape and TGLPhysicalShape collections, and interface functions enabling viewers to manage objects in these. The physical shapes defined the placement of copies of the logical shapes - see TGLLogicalShape/TGLPhysicalShape for more information on relationship

The scene can be drawn by owning viewer, passing camera, draw style & quality (LOD), clipping etc - see Draw(). The scene can also be drawn for selection in similar fashion - see Select(). The scene keeps track of a single selected physical - which can be modified by viewers.

The scene maintains a lazy calculated bounding box for the total scene extents, axis aligned round TGLPhysicalShape shapes.

Currently a scene is owned exclusively by one viewer - however it is intended that it could easily be shared by multiple viewers - for efficiency and synchronisation reasons. Hence viewer variant objects camera, clips etc being owned by viewer and passed at draw/select
