Abstract:
A method of modifying a display of a zone of a surface having an original shape, comprising the steps of:(a) defining outer constraints at boundaries of said zone as continuities G.sup.k along at least part of said boundaries, with k being an integer at least equal to minus one;(b) defining inner constraints G.sup.n as points or curves to be crossed by said zone when modified, with n being an integer at least equal to zero;(c) selecting a deformation direction law for all points of said zone;(d) defining an amount of deformation in each point of said zone as a result of a resilient deformation of a generalized infinite thin planar plate in equilibrium, respecting said outer and inner constraints; and(e) generating a modified zone as a surface resulting from a result of an application of said resilient deformation to said original shape in said zone.
