Remarks

The static class contains set of routines, which provide different operations with collection of points in 2D space. For example, finding the furthest point from a specified point or line.

Sample usage:

Copy

// create points' list
List<IntPoint> points = new List<IntPoint>( );
points.Add( new IntPoint( 10, 10 ) );
points.Add( new IntPoint( 20, 15 ) );
points.Add( new IntPoint( 15, 30 ) );
points.Add( new IntPoint( 40, 12 ) );
points.Add( new IntPoint( 30, 20 ) );
// get furthest point from the specified point
IntPoint p1 = PointsCloud.GetFurthestPoint( points, new IntPoint( 15, 15 ) );
Console.WriteLine( p1.X + ", " + p1.Y );
// get furthest point from line
IntPoint p2 = PointsCloud.GetFurthestPointFromLine( points,
    new IntPoint( 50, 0 ), new IntPoint( 0, 50 ) );
Console.WriteLine( p2.X + ", " + p2.Y );
