Interactive Non-Photorealistic Rendering Based on Hardware Acceleration
Jiening Wang · Journal of Engineering Graphics · 2005
Non-photorealistic rendering technique is to present data in a certain style that does not necessarily have a real-life analogue. This can help us to convey information more clearly both in geometry and design style. The method is very useful to CAD system and cartoon-style rendering. In this paper, we present an algorithm for extracting and rendering silhouette outlines of 3D polygonal meshes in image space. We also propose a lighting model by improving conventional Blinn-Phong lighting model for NPR. We implement all these approaches based on modern programmable graphics hardware acceleration. The experimental results show they can satisfy real-time interactive needs.
