Abstract:
We describe a method for rapidly producing a non-photorealistic rendering of an implicit surface. The rendering includes silhouettes and some shading near silhouettes to help indicate curvature. The method identifies silhouettes probabilistically, but we include strategies to make it likely that we find all silhouette curves, especially in multiple-frame sequences. The method is approximate, in the sense that the silhouette curves may suffer some position error.; the degree of approximation is determined in part by an adjustable parameter to a curve-tracing method, allowing a tradeoff of accuracy against speed.
