Windows, and more specifically Windows Movie Maker, are capable of running 3D Flash Animations. Windows Movie maker is the software bundled with Windows, to enable users to create and edit digital films. Files with the extension ".3DFA" are movie project files made using 3D Flash Animation. 3D flash animation is a popular tool for creating animated images and interactivity on the web and is used in websites such as Zazzle and Grouper to show product detail scenes. The Windows Movie maker interface looks similar to Adobe flash, however it does have its own unique features.
If you want to convert your pictures into 3D flash animations Windows Movie maker allows you to do this. There are a number of different ways you can go about this. The easiest is to use the "crop" tool in Windows Movie maker, then choose an existing picture to convert. There is a conversion option under the "Movie Tools" section of the "Movie" tab in Windows. A simple example of converting a JPEG file is to right click on the image and choose convert to JPEG.
The tools needed to create these animations vary between different programs. If you want to learn how to do this on the Mac, you can download a 3DFa viewer app that will allow you to view the converted images. These images will be rendered at the correct resolution for your purposes (i.e. they will not be blurred or pixilated). If you are unsure whether your PC will be able to run the 3D flash animator app, I would recommend downloading a trial version of the software first as most programs let you try it out before you buy.
