Local feature size

Local feature size refers to several related concepts in computer graphics and computational geometry for measuring the size of a geometric object near a particular point.


 * Given a smooth manifold $$M$$, the local feature size at any point $$x \in M$$ is the distance between $$x$$ and the medial axis of $$M$$.
 * Given a planar straight-line graph, the local feature size at any point $$x$$ is the radius of the smallest closed ball centered at $$x$$ which intersects any two disjoint features (vertices or edges) of the graph.
