示例1: CreateConvexHullAsClosedPolyline
internal static Polyline CreateConvexHullAsClosedPolyline(IEnumerable<Point> points) {
var convexHull = new Polyline(CalculateConvexHull(points)) { Closed = true };
#if TEST_MSAGL
foreach (var point in points) {
if (Curve.PointRelativeToCurveLocation(point, convexHull) == PointLocation.Outside) {
var hullPoint = convexHull[convexHull.ClosestParameter(point)];
// This can be too restrictive if very close points are put into the hull. It is probably
// better to clean up in the caller before doing this, but this assert can also be relaxed.
Debug.Assert(ApproximateComparer.Close(point, hullPoint, ApproximateComparer.IntersectionEpsilon * 20), String.Format("not CloseIntersections: initial point {0}, hull point {1}", point, hullPoint));
}
}
#endif // TEST_MSAGL
return convexHull;
}示例2: VerifyPointsAreInOrOnHull
public static void VerifyPointsAreInOrOnHull(IEnumerable<Point> points, Polyline hull)
{
// A convex hull may not pick up points that are just barely outside the hull because GetTriangleOrientation won't
// show a significant enough distance to consider them non-collinear.
foreach (var point in points)
{
if (Curve.PointRelativeToCurveLocation(point, hull) == PointLocation.Outside)
{
var hullPoint = hull[hull.ClosestParameter(point)];
if (!ApproximateComparer.CloseIntersections(point, hullPoint))
{
Validate.Fail(String.Format("not CloseIntersections: initial point {0}, closest hull point {1}", point, hullPoint));
}
}
