Curved2Geometry - a twofold curved geometry

Construction One defines with some 3D points the center curve and for some angles the orthogonal radial distances of the hull from these points. By specifying the maximum values, one determines the vertical and radial fineness of the representation. With a definition string of three characters one determines whether caps are to be generated and whether these are to be flat or smooth. The third character allows radial connection without seam or symmetrical geometry. For symmetrical geometry t…
