示例1: IntersectionWith
/// <summary>
/// Find intersection between Line3D and Plane
/// http://geomalgorithms.com/a05-_intersect-1.html
/// </summary>
/// <param name="line"></param>
/// <param name="tolerance"></param>
/// <returns>Intersection Point or null</returns>
public static Point3D IntersectionWith(Plane plane, Line3D line, double tolerance = float.Epsilon)
{

Point3D projectedPoint = plane.Project(line.StartPoint, line.Direction);
if (projectedPoint == line.StartPoint) { //Line lies in the plane
throw new InvalidOperationException("Line lies in the plane"); //Not sure what should be done here
} else { // Line and plane are parallel
throw new InvalidOperationException("NULLLLLLL");
}
}
var d = plane.SignedDistanceTo(line.StartPoint);
var u = line.StartPoint.VectorTo(line.EndPoint);
var t = -1 * d / u.DotProduct(plane.Normal);
