Geodesic curves in surfaces are not only minimizers of distance, but they are also the curves of zero geodesic (sideways) curvature. It turns out that this property makes patterns...

We present a competitive strategy for walking into the kernel of an initially unknown star-shaped polygon. From an arbitrary start point, s, within the polygon, our strategy find...

Abstract. In this study we compared human discrimination performance for real and virtual curved shapes. To simulate a curved shape we used a device that could independently orient...
