Rendering
• OnPreCull: Called before the camera culls the scene. Culling determines which objects are visible to the camera. OnPreCull is called just before culling takes place.
• OnBecameVisible/OnBecameInvisible: Called when an object becomes visible/invisible to any camera.
• OnWillRenderObject: Called once for each camera if the object is visible.
• OnPreRender: Called before the camera starts rendering the scene.
• OnRenderObject: Called after all regular scene rendering is done. You can use GL class or Graphics.DrawMeshNow to draw custom geometry at this point.
• OnPostRender: Called after a camera finishes rendering the scene.
• OnRenderImage: Called after scene rendering is complete to allow post-processing of the image, see Post-processing Effects.
• OnGUI: Called multiple times per frame in response to GUI events. The Layout and Repaint events are processed first, followed by a Layout and keyboard/mouse event for each input event.
• OnDrawGizmos Used for drawing Gizmos in the scene view for visualisation purposes.
