We present an algorithm for detecting and extracting the silhouette edges of a triangle mesh in real time using GPUs (Graphical Processing Units). We also propose a tessellation strategy for visualizing the mesh with smooth silhouettes through a continuous blend between Bézier patches with varying level of detail. Furthermore, we show how our techniques can be integrated with displacement and normal mapping. We give details on our GPU implementation and provide a performance analysis with respect to mesh size.
