Urban spaces consist of a complex collection of buildings, parcels, blocks and
neighbourhoods interconnected by streets. Accurately modelling both the appearance and …

In this paper we present an application framework that leverages geospatial content on the
World Wide Web by enabling innovative modes of interaction and novel types of user …

Visibility computation is a key element in computer graphics applications. More specifically,
a from-region potentially visible set (PVS) is an established tool in rendering acceleration …

Numerous systems have been developed to display large collections of data for urban
contexts; however, most have focused on layering of single dimensions of data and manual …

Achieving high rendering quality in the visualization of large particle data, for example from
large-scale molecular dynamics simulations, requires a significant amount of sub-pixel …

Interactive display and visualization of large geometric and textured models is becoming a
fundamental capability. There are numerous application areas, including games, movies …

Interactive visualization of massive models still remains a challenging problem. This is
mainly due to a combination of ever increasing model complexity with the current hardware …

In this paper we propose a global visibility algorithm which computes from-region visibility
for all view cells simultaneously in a progressive manner. We cast rays to sample visibility …

In modern clinical practice, planning access paths to volumetric target structures remains
one of the most important and most complex tasks, and a physician's insufficient experience …

We present an efficient technique to compute the potentially visible set (PVS) of triangles in
a complex 3D scene from a viewpoint. The algorithm computes a conservative PVS at object …
