示例1: ConvertToNonPeriodic
/// <summary>
/// We want to convert the periodic formulation into a non periodic formulation. To do
/// this we follow the instructions from Guilia at DevDept.
///
/// the things that need to be done to get the correct curve in Eyeshot are:
/// - add one last control point equal to the first to close the curve
/// - multiply the(x, y, z) coordinates of each control point by its w coordinate
/// - the degree p of your curve is given by the multiplicity of the last knot in the periodic knot vector, therefore you need to increase by 1 the multiplicity of the last knot, and by p the multiplicity of the first knot.
/// </summary>
/// <param name="controlPoints4D"></param>
/// <param name="knotArray"></param>
/// <param name="degree"></param>
private static void ConvertToNonPeriodic(ref Vector4[] controlPoints4D, ref double[] knotArray, int degree)
{
controlPoints4D = controlPoints4D.EndWith(controlPoints4D.First()).ToArray();
var last = knotArray.Last();
var first = knotArray.First();
knotArray = Enumerable.Repeat(first, degree).Concat(knotArray).EndWith(last).ToArray();
// We need to do some special handling to make it non periodic
