Nova4Phone 3D engine for Windows Phone 7 shows what the WP7 GPU is capable of

French developers Vertice and Bewise have developed an application that allows 3D models from a variety of applications, including industry standards like Maya and Blender, to be imported and viewed in the device itself.
