TGLSceneInfo Class Reference

Base class for extended scene context.

Scenes can be shared among several viewers and each scene needs to cache some viewer/camera/clipping specific state => this is a storage class for this data.

Sub-classes of TGLSceneBase can override the virtual CreateSceneInfo() method and in it instantiate a sub-class of TGLSceneInfo containing the needed information. See TGLScene and inner class SceneInfo; note that some casting is needed in actual methods as TGLRnrCtx holds the base-class pointer.
