Method Detail

compute

public int compute(RectL pInputRect,
                   PointL pInputPoint,
                   double pInputRadius,
                   PointL pOutputIntersection1,
                   PointL pOutputIntersection2)

Computes the intersection between a rectangle and the triangle that starts from a Point and goes to a circle centered on the rectangle's center

Returns:

CORNER_INSIDE if the Point is within the rectangle, CORNER_NONE if both intersections are on the same border, or a combination of CORNER_% that tells which rectangle's corner is included between both intersections
