Real Time Rendering of Small Expensive Environments

Real Time Rendering of Expensive Small Environments

One of the major goals of computer graphics is the rendering of realistic environments in real-time. One approach to this task is to use the newest features of graphics hardware to create complex effects which increase realism. The goal of this paper to propose a set of features which allows small environments to have comparable realism to much larger environments. These features will be geared...

Distributed Visibility Servers

This thesis describes techniques for computing conservative visibility exploiting viewpoint prediction, spatial coherence and remote visibility servers to increase the rendering performance of a walkthrough client. Identifying visible (or partially visible) geometry from an instantaneous viewpoint of a 3-D computer graphics model in real-time is an important problem in interactive computer grap...

Perceived Egocentric Distances in Real, Image-Based, and Traditional Virtual Environments

In virtual environments, perceived egocentric distances are consistently underestimated when compared to the same distance judgments in the real world. The research presented in this paper explores two possible causes for the compressed distance perception in virtual environments: (1) real-time computer graphics rendering, and (2) immersive display technology. Our results show there is a signif...

An Experimental Comparison of Perceived Egocentric Distance in Real, Image-Based, and Traditional Virtual Environments using Direct Walking Tasks

In virtual environments, perceived egocentric distances are often underestimated when compared to the same distance judgments in the real world. The research presented in this paper explores two possible causes for this reduced distance perception in virtual environments: (1) real-time computer graphics rendering, and (2) immersive display technology. Our experiment compared egocentric distance...
