Hello, I’m new here, and kinda new to animating too. I don’t know if this the right place to ask, or my question is dumb or not, but here goes.
As we know, it’s easy to make animation from this
http://i219.photobucket.com/albums/cc266/TheDarkmot/Toon%20Boom/ask1.jpg into this http://i219.photobucket.com/albums/cc266/TheDarkmot/Toon%20Boom/ask2.jpg
But what I want to do, animate hand from this
http://i219.photobucket.com/albums/cc266/TheDarkmot/Toon%20Boom/ask3.jpg to this http://i219.photobucket.com/albums/cc266/TheDarkmot/Toon%20Boom/ask4.jpg
But not by swing it to side, but by front. And not changing the drawing, just moving or any other tricks that I might not know. Skew and scaling doesn’t work since they will make the hand looks like paper thin.
Is this possible? Without changing the drawing?
I think the short answer to this is that there is no way to what you are asking.
The first example you give is simply a repositioning of the drawing. The actual artwork doesn’t change it’s shape as it straightens out.
The second version actually incorporates new shapes or images into the scene thus the computer would have to guess as to what the finished product would want to be.
If you must do it just the way you illustrate you should do this with drawing swaps. There are some great tutorials on how to do that. Much the the same way you would make an eye blink etc.
Some alternatives:
Turn the puppet to the front view when they start this motion so that you only have to draw it once then it becomes motion again.
If the hand and arm are separate… try skewing the arm shorter, then following it with the hand making the hand larger as it gets closer to the camera. (Just how large is up you depending on how close to the camera you want it to be). Once the hand is half way it should block out the arm entirely, thats when you flip it horizontally. If you do it fast enough it will barely be seen.
If you want the arms to appear to be moveing fast try drawing lines rather than shapes as the arm transitions.
Hope that helps.
Alright thanks 
I’ve already somewhat guess it, but still asking just in case there are hidden technique that I don’t know. Thanks for the answer
Tim,
I don’t know if this’ll help you.

it goes on about cell swapping. Your different arm shapes could be placed in those. I’m new to this though so I may be leading you a merry dance. Sorry in advance.
