Hi Kenzo,
I wouldn't implement this type of management by reassigning a single
osg::Camera with different setting but use a different Camera. I
would also leave alone the master Camera and instead prefer to
add/remove slave Cameras.
My guess to why you haven't been able to do what you want is the
rendering backend data structure that is assigned to the osg::Camera
to manage the the data accumulated during the cull traversal and which
is that traversed in the draw traversal. The osg::Camera methods
relating to this data structure is:
/** Set the Rendering cache that is used for cached objects
associated with rendering of subgraphs.*/
void setRenderingCache(osg::Object* rc) { _renderingCache = rc; }
/** Get the Rendering cache that is used for cached objects
associated with rendering of subgraphs.*/
osg::Object* getRenderingCache() { return _renderingCache.get(); }
Perhaps resetting this RenderCache to 0 would do the trick.
Robert.
