52 A QFrustumCulling class enables frustum culling of the drawable entities based on
53 the camera view and QGeometry bounds of the entities. If QFrustumCulling is present in
54 the FrameGraph, only the entities whose QGeometry bounds intersect with the camera
55 frustum, i.e. the view of the camera, are drawn. If QFrustumCulling is not present,
56 all drawable entities will be drawn. The camera is selected by a QCameraSelector
57 frame graph node in the current hierarchy. Frustum culling can save a lot of GPU
58 processing time when the rendered scene is complex.
