示例1: CircleCircleIntersection
/// <summary>
/// Returns the two intersection points between two circles.
/// </summary>
public static Vector2[] CircleCircleIntersection(Vector2 center1, Vector2 center2, float radius1, float radius2)
{
var D = center1.Distance7(center2);
//The Circles dont intersect:
if (D > radius1 + radius2 || (D <= Math.Abs(radius1 - radius2)))
{
return new Vector2[] { };
}
var A = (radius1 * radius1 - radius2 * radius2 + D * D) / (2 * D);
var H = (float)Math.Sqrt(radius1 * radius1 - A * A);
var Direction = (center2 - center1).Normalized2();
var PA = center1 + A * Direction;
var S1 = PA + H * Direction.Perpendicular2();
var S2 = PA - H * Direction.Perpendicular2();
return new[] { S1, S2 };
}示例2: GetCandidates
internal static Vector2[] GetCandidates(Vector2 from, Vector2 to, float radius, float range)
{
var middlePoint = (from + to) / 2;
var intersections = Geometry2.CircleCircleIntersection(
from, middlePoint, radius, from.Distance7(middlePoint));
