Convert 3D viewer to XNA from SlimDX

We have an existing 3D viewer written in C# and use SlimDX wrapping Direct3D9. The 3D viewer was developed as a Winform User Control. Please convert it to XNA as a WPF User Control. Some simple additional features are also required (see details below). ## Deliverables More details about our existing viewer: -- The viewer shows only one object - a virtual 3D human head, including geometry and texture. The face of the virtual head is continuously animated to generate expression and speech. -- The movement of the virtual 3D human head is controlled by external code, and thus can be treated as black box for this project. -- The viewer uses shader based rendering so it has some HLSL code. -- The existing viewer was basically developed as a part of a prototype so there is room to improve its structure. The source code can be provided. Additional features to add to the new viewer: -- Picking Find the actual point(s) of intersection. -- Eyeball rotation Rotate the eyeball parts of the virtual face when given a look-at direction. The geometry and texture of the eyeballs already exist. Deliverables: -- Completed C# source code; -- Necessary shader code; -- Any other necessary documentation. How to test Load and display a continuously animated 3D virtual human head. General requirements: -- The work must be overall optimal for visual effect and performance; -- The work should have simple and intuitive API to its client; a better programming interface is more important than maintaining the consistence with our existing viewer; -- The code must be compiled and run in C# NET 4.0/Visual Studio 2010; -- The code must be properly re-factored and well structured; -- The work must be high-quality and production-ready. To Bid Please give examples of your related previous work, e.g. XNA projects and general 3D programming. We've posted a deadline of 14 days. If you feel that is too short, please post your timeframe with your bid. * * *This broadcast message was sent to all bidders on Sunday May 20, 2012 10:07:04 PM: We might not have explained clearly one aspect of this project: This project is not about creating an ordinary WPF User Control, but rather it is more about 3D programming. What we want to display is a 3D virtual human head that continuously expresses emotions and speaks, which is very similar to what you would see in a 3D animation movie. As said in the requirement, even though you don’t need to create the animation, the 3D viewer will have to accommodate the 3D animation, texture, lighting, etc.
