Abstract
We propose a method to stylize individual lines and preserve their properties when the viewpoint is modified. As the camera position changes and view-dependent lines move across the surface, we track each line in order to generate the region of the surface in which they appear. We call this region the tracked area of the line. In our algorithm, we use the Gaussian Curvature for surface segmentation as well as to divide the contour lines at inflection points. Each line has an unique reference linked to its tracked area, that we use to check an indexed table from which we can recover its stylization after arbitrary camera movements. In this paper we show how each line only appears in a limited area of the surface corresponding to its tracked area and we also discuss and evaluate two different smoothing methods to deal with highly detailed models.
