3D Model in Windows Phone 7 using Silverlight

Question

I have to do a wp7 app with a 3D arrow rotating dynamically. The app will have alot os menus, so the best way is use Silverlight. How can I have a 3D object in silverlight? I have tools like Swift 3D to do the model. They generate .xaml code, but when I put that code in expression blender I have errors.

There are a different approach? I'm a little lost, because I'm new to Microsoft development platform.

Answer 2

You can make a flat 2D object and use a perspective transform, to transform it in 3D. You will get was it called a 2.5D projection. These two posts should help you: http://netindonesia.net/blogs/umifadilah/archive/2010/05/12/silverlight-3d-perspective-transform-on-windows-phone-7.aspx

If you need full 3D models, I'd recommend to try the Silverlight 3D engine Balder from CodePlex: http://balder.codeplex.com The main developer has recently written a good Coding4Fun article that might help you: Rubik’s Cube for Silverlight and Windows Phone 7 using Balder
