Visvalingam's algorithm was designed for caricatural line generalization. A distinction must be made between the algorithm and its operational definition, which includes the metric used to drive it. When the algorithm was first introduced, it was dem... Read More about Implications of Weighting Metrics for Line Generalization with Visvalingam’s Algorithm.

Formulated silhouettes for sketching terrain (2003)
Presentation / Conference Contribution
Whelan, J. C., & Visvalingam, M. (2003, June). Formulated silhouettes for sketching terrain. Presented at Theory and Practice of Computer Graphics, TPCG 2003, Birmingham, UK

The mathematical definition of silhouettes within NPAR is based on the assumption that they are the eye-centered projections of occluding contours on an imaging plane. However, occluding contours are insufficient for sketching the silhouettes of hill... Read More about Formulated silhouettes for sketching terrain.
