Near-optimal adaptive polygonization

Proceedings Computer Graphics International CGI-99, 1999
Consider a triangulation of the xy plane, and a general surface z=f(x, y). The points of the triangle, when lifted to the surface, form a linear spline approximation to the surface. We are interested in the error between the surface and the linear approximant.

Near-quadratic bounds for the motion planning problem for a polygon in a polygonal environment

Proceedings of 1993 IEEE 34th Annual Foundations of Computer Science, 2002
We consider the problem of planning the motion of an arbitrary k-sided polygonal robot B, free to translate and rotate in a polygonal environment V bounded by n edges. We show that the combinatorial complexity of a single connected component of the free configuration space of B is k/sup 3/n/sup 2/2/sup O(log(2/3)/ n).

Near Polygons from Partial Linear Spaces

Geometriae Dedicata, 1999
Starting from a partial linear space \({\mathcal S} =(P, {\mathcal L})\) the authors discuss four constructions which alter the structure of \({\mathcal S}\), thus obtaining infinitely many non-degenerate as well as degenerate near polygons. An incidence structure is called a partial linear space, if every line is incident with at least two points and ...
