What Gifted Apprentice does isn't quite 2D animation -- but it is as versatile as drawing by hand. And it isn't quite 3D animation -- but it is as easy as animating by character rig.
The process is simple. Pose a 3D armature into a key-frame, and draw your character over it in 2D. From there, Gifted Apprentice will try to figure out roughly what you character should look like in any other 3D orientations or poses.
Pose the armature into the next key frame. If Gifted Apprentice isn't quite on the mark, simply fix the mistakes. Gifted Apprentice will learn from you. Quickly.
Pose the next key frame, and you shouldn't need to make as many corrections this time.
Repeat the process until you're done animating.
As Gifted Apprentice learns more and more, you'll have to draw less and less. Teach it enough, and it will even be able to infer an approximate 3D model. You can't use it yet, but it'll be there in its mental model. In future versions, Gifted Apprentice will use that 3D model to automatically provide a basis for 2D lighting and shadowing -- the vector output of which, you can modify in much the same way you draw anything else in the program.
Here, I'll be showcasing features and posting progress updates, -- and I'd certainly appreciate suggestions, feature requests, and eventually alpha testers.
The ultimate goal is to make animation accessible to hobbyists, amateurs, students, or anyone lacking an army of inbetweeners. Occasionally, I'll take weeks off here or there to work on other small and neat but unrelated things. Hopefully people appreciate those quick creative endeavors enough on their own that they might like to offer support.
Best wishes -- and to those who've already been following me for a while: thank you for everything.
