I’m still quite a noob in terms of animation, and I’m wondering if it’s possible to animate a 2D plane to scale out horizontally, then appear to extrude 90 degrees from its end point… like some of those popup graphics on sci-fi HUDs in first person shooters. I tried the following a path technique, http://www.youtube.com/watch?v=qsST6pXVptI which worked okay, but I couldn’t get quite a perfect 90 degree angle even after adjusting all the settings.
I also tried shapekeys, but couldn’t quite figure out how to make the plane change directions (I know you can’t add/subtract any more vertices than you started with). Is there a way to animate this? Or can one animate an extrude?
If you know of any helpful links to point me in the right direction or if you have any advice, I would be extremely grateful!
