3d Models in WPF

My question is simply

1. How can I get a file with .3ds or .obj extension loaded in a wpf project?

2. How can I drag and drop that 开发者_JS百科3d model with the mouse?

(I'm doing a 3d chess project)

1. Blend has support for loading an obj file and converting it to xaml. Unfortunately, there is no support for 3DS in the box - getting 3DS files requires 3rd party software such as Reader3ds.

2. You'll need to write your own hit testing, and handle this yourself.
