Title: GRIDLESS HALFTONING OF FREEFORM SURFACES VIA A COVERAGE OF ISOPARAMETRIC CURVES.
Authors: G. Elber
PDFNot Available
Abstract: A black and white non-photorealistic visualization scheme of scenes composed of freeform surfaces is presented. A freeform surface coverage is constructed using a set of isoparametric curves. The density of the isoparametric curves is set to be a function of the illumination of the surface, determined using a simple lighting model. The outcome is an aesthetic and attractive gridless halftoning that employs line and curve based drawings and is suitable for printing publication.
