Three-Dimensional Proxies for Hand-Drawn Characters

Algorithms for finding proxies at three levels of detail (points, shapes, joint hierarchy). The proxies allow simulated cloth and other objects to interact with a 2D hand-drawn character.

How Do Humans Sketch Objects?

This paper analyzes how well humans and computers are able to discern rough sketches of everyday objects. Based on the analysis, the paper develops a computational model of sketch understanding and demonstrates an interactive sketch-recognition system.

CrossShade: Shading Concept Sketches Using Cross-Section Curves

This paper facilitates creation of 3D-looking shaded production drawings from concept sketches. The method uses artist-drawn cross-sectional curves to automatically infer 3D normals across the drawn objects and uses this normal field to shade a wide range of concept sketches with a variety of rendering styles.
