Abstract:
This paper presents an interactive non-photorealistic rendering
(NPR) system that stylizes and renders outdoor scenes captured by
3D laser scanning. In order to deal with the large size, complexity
and inherent incompleteness of data obtained from outdoor scans,
our system represents outdoor scenes using points instead of traditional
polygons. Algorithms are then developed to extract, stylize
and render features from this point representation. In addition to
conveying various NPR styles, our system also promises consistency
in animation by maintaining stroke coherence and density.
We achieve NPR of large scale data at interactive rates by designing
novel data structures and algorithms as well as leveraging new
features of commodity graphics hardware. Our experiments have
shown that our system offers a novel experience of large real world
environment navigation that is more aesthetic and informative than
that offered by traditional photorealistic rendering systems.
