% ex03_polygon.m — A polygon given by its vertices.
%
% dpoly is the signed distance to a polygon defined by the vertex list pv
% (first vertex repeated at the end to close it). pv is passed both as the
% distance-function parameter and as the set of fixed points, so the mesh
% boundary follows the polygon edges exactly.
