Abstract:
This paper presents a novel object-space line drawing algorithm that can depict shape with view dependent feature lines in real-time. Strongly inspired by the Laplacian-of-Gaussian (LoG) edge detector in image processing, we de?ne Laplacian Lines as the zerocrossing points of the Laplacian of the surface illumination. Compared to other view dependent features, Laplacian lines are computationally ef?cient because most expensive computations can be pre-processed. Thus, Laplacian lines are very promising for interactively illustrating large-scale models.
