We present a method for drawing lines on an object that depict both the shape and shading of the object. To do so, we construct a gradient field of the diffuse intensity of the su...

We present an interactive modelling technique, which reconstructs three-dimensional objects from user-drawn twodimensional strokes. We first extract a skeleton from the 2D contour...

We present a new fast approach for surface segmentation of thin structures, like vessels and vascular trees, based on Fast Marching and Level Sets methods. Fast Marching allows se...

The factorization method [1] is a feature-based approach to recover 3D rigid structure from motion. In [2], we extended their framework to recover a parametric description of the ...

: Some example effects achieved by our extended toon shader: continuous levels of abstraction (a); abstraction of near-silhouette regions: smoothing (b), and opacity (c); backlight...
