Abstract
Traditional methods for creating dynamic objects and
characters from static drawings involve careful tweaking
of animation curves and/or simulation parameters. Sprite
sheets offer a more drawing-centric solution, but they do
not encode timing information or the logic that determines
how objects should transition between poses and cannot
generalize outside the given drawings. We present an approach for creating dynamic sprites that leverages sprite
sheets while addressing these limitations. In our system,
artists create a drawing, deform it to specify a small number of example poses, and indicate which poses can be
interpolated. To make the object move, we design a procedural simulation to navigate the pose manifold in response to external or user-controlled forces. Powerful
artistic control is achieved by allowing the artist to specify both the pose manifold and how it is navigated, while
physics is leveraged to provide timing and generality. We
used our method to create sprites with a range of different
dynamic properties.
