I have never used Flash before!
I have created a 3D model in Autodesk Maya and I would like to use it to create something a user can interact with i.e. rotate it or zoom in and out using a mouse. I have been told that if I create a 360 degrees rotation animation in Maya and render it into JPEGs I can then import them into Flash. The next part is where I need help! Is there a way of doing this?
If you have created the jpegs, you can import them into Flash using the Import command found in the File options of the toolbar. If the images are named in some sort of sequencial maner, Flash should recognize this and ask if you want the whole series imported. I believe it also offers you the ooportunity to import them into the timeline, in which case they would be planted frame after frame. So you will probably want to create a movieclip symbol and import the images into its timeline while you have it open for editing.
Whatever interaction you want to involve will dictate what you need to do internally to make the movieclip react to interaction. Being that you have never used Flash before, you need to learn how to implement event listeners, for either or both the mouse and the keyboard.
Your best bet at finding some help with learning about event listeners would probably be to search Google using terms like "AS3 MouseEvent tutorial".
