Abstract
A high quality surface representation is indispensable for a hydrodynamic numerical model, which is related to nature. Standard algorithms for meshing are not able to guarantee these requirements. Applied methods approximate the surface by patches. As a result an implementation for a b-spline surface was realised and tested. The used method “tensor product b-spline surface” is defined by an array of control points, called de Boor points. The associated b-spline functions are defined in every local segment. Changes at one point of the control point mesh result only in local changes of the b-spline surface.
