This is a still image of a cone tree file system traversal written by Jeromy Carriere for his final project, Winter 1994. The following is a short description of the project: A number of systems have been implemented that attempt to allow a user to view large hierarchies, centered around the use of three dimensional visualization in general. Cone trees are one such technique. Briefly, a cone tree is a three dimensional representation of hierarchical information in which one node of a tree is located at the apex of a cone, and all of its children are arranged around the circular base of the cone. The goal of a cone tree visualization is to present a structure in such a way that the entire hierarchy, or a large percentage of it, is visible without scrolling. 'fsvis' is an implementation allowing visualization of arbitrarily large hierarchies while retaining user control. This goal is accomplished by augmenting cone trees with several graphical and interaction techniques: usage-based filtering, animated zooming, hand-coupled rotation, fish-eye zooming, coalescing of nodes, texturing, effective use of colour for depth cueing, and the applications of dynamic queries. The fsviz system also improves upon earlier cone tree visualization systems through a more elaborate node layout algorithm.
