Fast 3D cartoon rendering with improved quality by exploiting graphics hardware
Johan Claes, Fabian Di Fiore, Gert Vansichem, Frank Van Reeth · 2001
Our work in the area of non-photo-realistic rendering (NPR) focuses on visualising 3D models in a cartoon rendering style: the geometrical objects are internally coloured using two or three colours, while simultaneously using an explicit outline. Many NPR techniques are timeconsuming processes, whereas we aim at real-time rendering performance on mainstream graphics PC hardware without losing a high image quality. Particular emphasis is also put on getting smooth transition borders between the bi-tonal cartoon-colours by applying an object precision triangle subdivision technique. Rapidly finding these transition borders as well as silhouette edges is a topic of a new algorithm. As silhouette lines and light effects are useful indicators for computer vision, this algorithm also looks interesting for applications in that field.
