We present an approximation method for offset curves of polygons on an oblate ellipsoid using implicit algebraic surfaces. The polygon on the ellipsoid is given by a set of vertices, i.e. points on the ellipsoid. The edges are the shortest geodesic p

A novel design and manufacturing pipeline for Additive Manufacturing is presented. The architecture of the pipeline is motivated by the observation that the conventional pipeline is unnecessarily complex. Most of the time, only a small set of program

In this paper we present an approximation method for a geodesic circle passing through three points on an oblate ellipsoid. Our method uses a prolate ellipsoid passing through the three points, and the new approximation curve is the intersection of t

A topological interlocking configuration is an arrangement of pieces shaped in such a way that the motion of any piece is blocked by its neighbors. A variety of interlocking configurations have been proposed for convex pieces that are arranged in a p

Topological Interlocking is a design technique to generate non-monolithic structures and composite materials. A traditional topological interlocking assembly consists of convex blocks arranged in a single layer. A peripheral structure provides suppor

In this paper we derive a sequence of linear normal (LN) curves b 2 n of degree 2 n which are G n endpoint interpolations of a circular arc and have approximation order 2 n + 2 . This is an extension of the circle approximation method by LN Bezier cu

We report on 3D printing of artifacts with a structured, inhomogeneous interior. The interior is decomposed into cells defined by a 3D Voronoi diagram and their sites. When printing such objects, most slices the printer deposits are topologically the

We present an approximation method of circular arcs using linear-normal (LN) Bezier curves of even degree, four and higher. Our method achieves G m continuity for endpoint interpolation of a circular arc by a LN Bezier curve of degree 2m, for m = 2 ,

The problem of geometric (model and system) interoperability is conceptualized as a non-trivial generalization of the problem of part interchangeability in mechanical assemblies. Interoperability subsumes the problems of geometric model quality, exch
