Hi, First, great toolkit, thank you! 

holes in the box, what should I do?

The best solution would be to create a MeshGeometry where the holes are modelled. It should not be difficult to do the tessellation if the holes have regular shape.

I would not recommend using textures with transparency to show 'holes' with wpf 3d...

var point3d_Out = new[] {new Point3D(0, 0, 0), new Point3D(6, 0, 0), new Point3D(4, 3, 0), new Point3D(6, 7, 0), new Point3D(0, 7, 0)};

var point3d_Hole = new[] {new Point3D(1, 2, 0), new Point3D(3, 2, 0), new Point3D(2, 4, 0), new Point3D(3, 5, 0), new Point3D(1, 5, 0)};

The hole was created by using CuttingEarsTriangulator.Triangulate to you Is there any plan to support.

I don't think the ear clipping method supports holes (http://en.wikipedia.org/wiki/Polygon_triangulation).

I have not planned to implement other triangulation methods, but maybe you can use code from other .net libraries?

Other ". NET libraries" could not be found

hard to sell in the hole  wpf3d

I can not speak English well.
So, more brutal.
google translator, I can not thank you enough  

^^;; Hahaha


Thank you so much for letting me answer
