New requirement on Create2D(IVertex2D)

[mc0re]

Why is there a "new" requirement? IVertex2D only has read-only properties, so a constructor with parameters is necessary, whilst a parameterless constructor (the result of "new" requirement) is pointless, unless you do some hefty reflection tricks...

I'm sorry I'm not understanding. IVertex2D is an interface. This is the extent of the code:

    public interface IVertex2D
    {
        /// <summary>
        /// Gets the x.
        /// </summary>
        /// <value>The x.</value>
        double X { get; }

        /// <summary>
        /// Gets the y.
        /// </summary>
        /// <value>The y.</value>
        double Y { get; }
    }

Hi, is it possible to use Create2D on coplanar points which do not lie on Z=0 plane ? Can it be used to calculate 2D hull for points on arbitrary oriented planes or plane normal should always be 0,0,1
