getVertices()

Returns the polyline’s local vertices without scaling or rotation and without being offset by the polyline position.

Результат:float[]

getTransformedVertices()

Результат:float[] vertices scaled, rotated, and offset by the polyline position.

getLength()

Результат:float Returns the euclidean length of the polyline without scaling

getScaledLength()

Результат:float Returns the euclidean length of the polyline

calculateLength()
