isClockwise (bool *isColinear=nullptr) const

Returns true if PolyLine is clockwise-oriented. If isColinear is non-null, it receives true if all points are colinear.
bool

isCounterclockwise (bool *isColinear=nullptr) const

Returns true if PolyLine is counterclockwise-oriented. If isColinear is non-null, it receives true if all points are colinear.

reversed () const
bool

contains (const vec2 &pt) const

Returns whether the point pt is contained within the boundaries of the PolyLine.
double

calcArea () const

Returns the unsigned area of the polygon. Assumes closed and no self-intersections.
T

calcCentroid () const

Returns the centroid or "center of mass" of the polygon. Assumes closed and no self-intersections.
