		std::vector< CMRMMeshGeom > &	lodMeshs,
		uint	nWantedLods = 10,
		uint	divisor = 50
	)			[private]

build all LODs from a baseMesh.

NB: the coarsestMesh is stored in lodMeshs[0], and has no geomorph info since it is the coarsest mesh. nWantedLods are created (including the coarsestMesh).

Parameters:

	lodMeshs	array created by the function (size of nWantedlods).
	nWantedLods	number of LODs wanted.
	divisor	the coarsestMesh will have baseMesh.Faces.size()/divisor faces.
