COMPUTER-AIDED DESIGN OF DEVELOPABLE HULL SURFACES

An algorithm mathematizes a developable surface design procedure for the digital computer. Given points on a pair of boundary curves, the algorithm generates spline- approximating polynomials to represent the boundary curves and computes a set of closely spaced rulings which lie in the surface spanning the boundary curves. Offsets to the surface are then computed at any specified transverse, vertical, or horizontal plane cutting the surface. The procedure emphasizes freedom of shape but does not guarantee the existence of a developable surface. In this case, the results will be information describing the developability violation rather than offsets describing the surface. The outstanding advantages of a computer-aided approach to developable surface design are speed and precision.
