Detailed Description
Level of Detail Node, Children should be ordered with the highest resolution PagedLODChild first, through to lowest resolution PagedLODChild last. The PagedLODChild struct stores the minimumScreenHeightRatio and child that it's associated with. During culling the minimumScreenHeightRatio is used as a minimum ratio of screen height that a bounding sphere needs to occupy in order for the associated child to be traversed. Once one child passes this test no more children are checked, so that no more than one child will ever be traversed in a record traversal. If no PagedLODChild passes the visible height test then none of the PagedLOD's children will be visible. During the record traversals the Bound sphere is also checked against the view frustum so that PagedLOD's also enable view frustum culling for subgraphs so there is no need for a separate CullNode/CullGroup to decorate it.
