Authoring and Animating Painterly Characters

To expand the range of possible visual styles for digital characters in CG animation, 3D stroke-based paintings are deformed using standard rigging tools and a novel configuration-space keyframing algorithm for authoring stroke effects.

Ink-and-Ray: Bas-Relief Meshes for Adding Global Illumination Effects to Hand-Drawn Characters

This ink-and-ray framework enables production of a richer look for traditional animation by enhancing hand-drawn artwork with global illumination effects previously only found in complex 3D pipelines.

Computing Smooth Surface Contours With Accurate Topology

A method for accurately computing the contours of a smooth 3D surface for stylization. The approach generates, for each viewpoint, a triangle mesh with contours that are topologically equivalent to those of the original surface.

Fast Multipole Representation of Diffusion Curves and Points

This paper proposes an efficient representation for diffusion curves, extends it to new primitive diffusion points, and demonstrates the representation's speed and flexibility with three new applications for vector graphics: Poisson cloning, multi-layer composition, and animation creation.

EZ-Sketching: Three-Level Optimization for Error-Tolerant Image Tracing

The EZ-Sketching technique automatically corrects sketch lines roughly traced over single images via three-level optimization based on the image features being traced alone. The corrected sketches show closer resemblance to the traced images and are often aesthetically more pleasing, as confirmed by the user study.
