METHOD FOR THE GEOMETRIC DESIGN OF SPATIAL MESHES USING NURBS SURFACES

A method for obtaining a design with the geometry of a spatial mesh formed by a plurality L of linear entities 1', characterized in that it comprises the steps of: choosing three points (C00 C0n Cn0) in a plane that defines a triangle; choosing a point (O) outside said plane; choosing an order of complexity n, in which n is a natural number greater than or equal to 1; calculating a set of control points C¡j in said triangle, which depend on n and on the three points chosen (C00 C0n Cn0); choosing weights?¡j, in which each one of these weights is connected with a control point C¡j; transforming the set of control points C¡j into a plurality of points P¡j that define a control polyhedron; obtaining a NURBS surface from said control polyhedron; within the plane defined by said points (C00 C0n Cn0), defining an interlattice with a plurality L of sides 1; transforming said plurality L of sides 1 into a plurality of linear entities 1' constituting said spatial mesh.
