Abstract

Animating models using traditional 3D modelling and animation packages is complex and difficult for novice users to use. A sketch-based articulated figure animation tool is introduced that provides users with an intuitive interface to pose and animate skeletons of any topology easily. An isomorphic mapping between the sketch and the skeleton is determined and a recursive algorithm poses the skeleton so that it matches the pose sketched. It is shown how sketch- and depth ambiguity can be resolved using disambiguation information and pressure sensitivity. The tool developed allowed novice users to successfully and easily sketch stick figures to pose articulated figures for sketch-based animation.

A Method for Animating Children’s Drawings of the Human Figure
Children’s drawings have a wonderful inventiveness, creativity, and variety to them. We present a system that automatically animates children’s drawings of the human figure, is robust to the variance inherent in these depictions, and is simple and ...
Differential blending for expressive sketch-based posing
SCA '13: Proceedings of the 12th ACM SIGGRAPH/Eurographics Symposium on Computer Animation

Generating highly expressive and caricatured poses can be difficult in 3D computer animation because artists must interact with characters indirectly through complex character rigs. Furthermore, since caricatured poses often involve large bends and ...
