SheetAnim - From Model Sheets to 2D Hand-drawn Character Animation

摘要

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 provides a very good starting point for novice animators that can be then improved to create the final, desired animation.
