Abstract—We present a Sketch-Based Interface that allows
non-expert users to create an animation from just pencil and
paper. The interface works as a fast mockup tool for creating
animations - turning the user’s freehand 2D sketches into 3D
animations. To facilitate animation construction in offline or
computer-scarce scenarios, special emphasis is placed on paperbased instead of tablet-based sketches. The interface makes use
of stroke shape, proximity, and orientation to give the user’s
drawings an animated interpretation. These Sketches use a 2D
vocabulary of symbols, representing actors, actions and their
relations. Custom symbols are defined by the user, and then
associated with the relevant 3D assets within a database. The final
composition of the sketches is passed into the system, employing
image processing techniques for symbol recognition, and finally
converting the user’s intentions into a 3D animation.
