| Developable surfaces (DevSurfs) can be built out of flat plate and fabricated by bending alone, without stretching of any portion. --The bottom model combines 2 DevSurfs, 'topside' and 'bottom', and a narrow, compound-curved CLoftSurf 'chine_strake' between them. The 'bow-cone' is a RuledSurf, also developable. | |
