MODEL FABRICATION USING SURFACE LAYOUT PROJECTION

The paper presents a model fabrication scheme that automatically appro ximates a model whose boundary consists of several freeform surfaces b y developable surfaces and then unrolls these developable surfaces ont o a plane. The model can then be fabricated by assembling the sets of developable surfaces which have been cut from planar sheets and rolled back to their proper Euclidean locations. Both the approximation and the rolling methods can be made arbitrarily precise.
