متن کاملTangled Tangles
The Tangle toy [Zaw15, Zaw85] is a topological manipulation toy that can be twisted and turned in a variety of different ways, producing different geometric configurations. Some of these configurations lie in 3D space while others may be flattened into planar shapes. The toy consists of several curved, quarter-circle pieces fit together at rotational/twist joints. Each quarter-circle piece can ...
متن کاملTangled Splines
Extracting shape information from object boundaries is a well studied problem in vision, and has found tremendous use in applications like object recognition. Conversely, studying the space of shapes represented by curves satisfying certain constraints is also intriguing. In this paper, we model and analyze the space of shapes represented by a 3D curve (space curve) formed by connecting n piece...
متن کاملTangled Thrackles
A tangle is a graph drawn in the plane so that any pair of edges have precisely one point in common, and this point is either an endpoint or a point of tangency. If we allow a third option: the common point may be a proper crossing between the two edges, then the graph is called a tangled thrackle. We establish the following analogues of Conway’s thrackle conjecture: The number of edges of a ta...
