I’ve just received an e-mail from Electric Rain saying that their product ZAM 3D was updated. For those of you, who don’t know what it is, it is a 3D objects-generator for XAML. Instead of spending hours of researching Videoport3D, the Meshes, ModelCollection, etc, you design your object in the application, or import a standard 3D scene there. Anyway, they updated ZAM 3D to work fine with the May CTP of Avalon. They say the Rotation Animation has been changed a lot since the March 2005 release.
If you are working with XAML + 3D, ZAM 3D would be definately useful to you, you can get it from Electric Rain Web-Site.
