Abstract

We propose a system for real-time sketching of human faces. On the basis of a three-dimensional description of a face model, characteristic line strokes are extracted and represented in an artistic way. In order to enrich the results with details that cannot be determined analytically from the model, surface and anchor strokes are supplemented interactively and are maintained during animation. Because of the real-time ability of our rendering pipeline the system is suitable for interactive facial animation. Thus, interesting areas of application within the range of the virtual avatars are possible.
