Abstract
Methods, systems and apparatus which resample a primal mesh signal composed of primal points associated with primal mesh vertices of a primal mesh connectivity of a primal mesh producing a dual mesh signal composed of dual points associated with primal mesh faces of said primal mesh connectivity. The dual points are computed by minimizing a quadratic energy function. The quadratic energy function is composed of a sum of square terms. The invention also constructs a dual mesh from a primal mesh, with the dual mesh signal constructed with the resampling method. It also smoothes a primal mesh signal of a primal mesh. It also constructs a primal-dual mesh from a primal mesh, with the primal-dual mesh connectivity of said primal-dual mesh constructed using a prior art method, and the primal-dual mesh signal constructed by concatenating said primal mesh signal and a dual mesh signal computed with the resampling method.
