bool Is CCW Ordered Plane Map(const geo graph& G)<br />

Equivalent to Is Plane Map(G) and Is CCW Ordered(G).<br />

bool Is CCW Weakly Ordered Plane Map(const geo graph& G)<br />

Equivalent to Is Plane Map(G) and Is CCW Weakly Ordered(G).<br />

void SORT EDGES(geo graph& G)<br />

Reorders the edges of G such that for every node v the edges in A(v)<br />

are in non-decreasing order by angle.<br />

template <br />

bool Is CCW Convex Face Cycle(const geo graph& G, const edge& e)<br />

returns true if the face cycle of G containing e defines a counterclockwise<br />

convex polygon, i.e, if the face cycle forms a cyclically increasing<br />

sequence of edges according to the compare-by-angles ordering.<br />
