Spherical Fibonacci grids (SFG) yield extremely uniform point set distributions on the sphere. This feature makes SFGs particularly well-suited to a wide range of computer graphics applications, from numerical integration, to vector quantization, amo

Rendering photorealistic images is a costly process which can take up to several days in the case of high quality images. In most cases, the task of sampling the incident radiance function to evaluate the illumination integral is responsible for an i

PBTree — A new progressive and hierarchical representation for network-based navigation in densely built urban environments

Autor: Patrick Gioia, Christian Bouville, Jérôme Royan

Publikováno v: Annales Des Télécommunications. 60:1394-1421

This paper describes a novel progressive and hierarchical representation for densely built urban areas. It aims at navigating through huge urban environments with network-based client-server systems. Thanks to this method, navigation is no longer lim
