3D Graphing Package For C# Winforms?

I'm 开发者_运维问答using ZedGraph for my 2D graphing needs, but for a project, I need something that does 3d graphing. What is the best package I can use for this? I'd like the Graph Panes to be as easy to manipulate as with ZedGraph.

Edit: By 3D, I mean I want to be able to specify an x,y,z to get a surface. Thanks!

Using the source code that can be found in the link posted just below as well as WPF you can create a pretty good 3d graph, it's nothing groundbreaking but it might suit your needs:

In principle you can create a bitmap using MathGL and display it. MathGL is cross-platform GPL (LGPL for core) plotting library which can plot 2- and 3-ranged data. However, I'm not sure what you can use C++ classes from C#. But C-interface should work.
