Detailed Description

Class to render an OpenInventor scene in a Qt OpenGL window.

RenderArea creates a 3D rendering window as a child of another widget. Use the setSceneGraph() method to specify the scene graph to be rendered.

A SceneExaminer node is typically used to allow the user to manipulate the scene camera.
