Abstract:
We present an intuitive method to create 2D hand-drawn character animation suitable for novice animators.
Given the 2D model sheet of the character that shows how the character looks from the front and side, our
method can generate sketched views of the character from any direction, using the sketch stroke style used in
the model sheet. Subsequently, our system can generate an animation of the character using motion capture
data, and render it using the same sketched strokes. Our method is not only able to reproduce the sketch stroke
style, but also the colours and other character details that the animator adds to the model sheet. The method
can resolve occlusion correctly, both due to moving body parts and change in orientation of the character with
respect to the camera. The animator can interactively change the sketch style, colours or other details, at any
frame, as required. The animation generated by our method has the fluid style of hand sketched animation, and
provid
es a very good starting point for novice animators that can be then improved to create the final, desired
animation.
