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.
