void Buffer ( )
bool ClosestOnHull ( List< HalfPlane >  halfPlanes,
Vector2  query,
out Vector2  result 
)
private

Calculates the point closest to query that is outside all half planes.

Expected running time O(n) if the half planes are in random order. Worst case running time O(n^2).

Returns
true if there is such a point, false if there is not

static

Returns the intersection factors for line 1 and line 2.

The intersection factors is a distance along the line start - end where the other line intersects it.

intersectionPoint = start1 + factor1 * (end1-start1)
intersectionPoint2 = start2 + factor2 * (end2-start2)

Lines are treated as infinite.
false is returned if the lines are parallel and true if they are not.
