Thoroughly revised, this third edition focuses on modern techniques used to generate
synthetic three-dimensional images in a fraction of a second. With the advent of …

Visibility algorithms for walkthrough and related applications have grown into a significant
area, spurred by the growth in the complexity of models and the need for highly interactive …

An increasingly popular use of computing devices is to allow a user the ability to interact with
their physical Surroundings. For example, handheld computers can provide the user with …

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

Accordingly, the present invention is directed to identi fying the location of a user without
relying on dedicated infrastructure and a central authority. Additionally, the present invention …

Visualization of very complex scenes can be significantly accelerated using occlusion
culling. In this paper we present a visibility preprocessing method which efficiently computes …

Visibility computation was crucial for computer graphics from its very beginning. The first
visibility algorithms in computer graphics aimed to determine visible surfaces in a …

In this paper, occlusion culling techniques that appeared in the last decade are reviewed.
Occlusion culling techniques are responsible for reducing the polygons rendered by the …

PCT patent application number PCT/US2011/051403 further claims the benefit of the earlier
filing date of US Provisional Application 61/384,284 entitled “System and Method of …

In this paper, we present a single-pass technique to voxelize the interior of watertight 3D
models with high resolution grids in realtime during a single rendering pass. Further, we …
