Method Details

computeArea

public float computeArea(Polygon2D_F32 a,
 Polygon2D_F32 b)

Computes the area of the intersection between the two polygons.

Note: the area result has little more accuracy than a float This is true even if the polygon is specified with floats.

Parameters:

a - Polygon A

b - Polygon B

Returns:

area of intersection. Negative if the order (CW vs CCW) do not match.
