Systems supporting the visualization and animation of algorithms, programs, and computations have focused primarily on two-dimensional graphics to date. In this paper we identify the need for three-dimensional graphics in these types of displays, and we describe how 3D imagery best can be used for visualizing computations. We also introduce an anim...
We propose a Virtual Reality interface for creating and manipulating textual and hypertextual information. Many current hypertext systems include concept maps in two dimensions. Our system, called the World Processor, offers the user a three-dimensional concept map. It allows the user to move through the map while exploring existing objects and the...
Glyphmaker is an interactive system for data visualization and analysis that is built in a dataflow environment. Glyphmaker provides a quite general platform for user-defined visualizations, one that can be extended in many ways and that, in particular, offers the first stage for an integrated visualization/analysis system. It is well-suited for th...
Overview diagrams are one of the best tools for orientation and navigation in hypermedia systems. However, constructing effective overview diagrams is a challenging task. This paper describes the Navigational View Builder, a tool which allows the user to interactively create useful visualizations of the information space. It uses four strategies to...
Our work concerns visualizing the information space of hypermedia systems using multiple hierarchical views. Although overview diagrams are useful for helping the user to navigate in a hypermedia system, for any real-world system they become too complicated and large to be really useful. This is because these diagrams represent complex network stru...
In its current implementation, the World-Wide Web lacks much of the explicit structure and strong typing found in many closed hypertext systems. While this property probably relates to the explosive acceptance of the Web, it further complicates the already difficult problem of identifying usable structures and aggregates in large hypertext collecti...
Annotation is a key operation for developing understanding of complex data or extended spaces. We have developed a flexible set of annotation tools that can be placed in a variety of applications. These tools offer a full set of capabilities for inserting, iconizing, playing back, and organizing annotations in a virtual space. They also have an int...
Information visualizations must allow users to browse information spaces and focus quickly on items of interest. Being able to see some representation of the entire information space provides an initial gestalt overview and gives context to support browsing and search tasks. However, the limited number of pixels on the screen constrain the informat...
We present a virtual reality application that allows users to access embedded information within an immersive virtual environment. Due to the richness and complexity of this environment, interaction between the user and the system requires efficient and easy-to-use techniques. We present tools for user control of the system, travel through the envi...
