Three dimensional scenes are typically modeled using a single, fixed resolution model of
each geometric object. Renderings of such a model are often either slow or crude, however …

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 …

We describe an adaptive display algorithm for interactive frame rates during visualization of
very complex virtual environments. The algorithm relies upon a hierarchical model …

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 …

Virtual environment research has focused on interactive image generation and has largely
ignored acoustic modeling for spatialization of sound. Yet, realistic auditory cues can …

We present hierarchical occlusion maps (HOM) for visibility culling on complex models with
high depth complexity. The culling algorithm uses an object space bounding volume …

This paper presents a practical technique to automatically compute approximations of
polygonal representations of 3D objects. It is based on a previously developed model …

A difficult challenge in geometrical acoustic modeling is computing propagation paths from
sound sources to receivers fast enough for interactive applications. This paper describes a …

Realistic modeling of reverberant sound in 3D virtual worlds provides users with important
cues for localizing sound sources and understanding spatial properties of the environment …

We present a new method that utilizes path coherence to accelerate walkthroughs of
geometrically complex static scenes. As a preprocessing step, our method constructs a BSP …
