Detailed Description

SoRenderArea encapsulates the features of SoQtRenderArea in an Inventor Node.

SoRenderArea is used standalone and as a base class to the more complex viewers SoFullViewer, SoExaminerViewer, ... SoRenderArea implements a Movie Recorder, this is extended in the more complex viewers where there is a notion of a camera. For additional details, see the html documentation of SoRenderArea in MeVisLab.
