Two-handed Interactive Stereoscopic
Visualization
Abstract
This paper describes a minimally immersive interactive system for
visualization of multivariate volumetric data. The system, SFA, uses
glyph-based volume rendering which does not suffer the initial costs
of isosurface rendering or voxel-based volume rendering, while
offering the capability of viewing the entire volume. Glyph rendering
also allows the simultaneous display of multiple data values per
volume location. Two-handed interaction using three-space magnetic
trackers and stereoscopic viewing are combined to produce a minimally
immersive volumetric visualization system that enhances the user's
three-dimensional perception of the data. We describe the usefulness
of this system for visualizing volumetric scalar and vector data. SFA
allows the three-dimensional volumetric visualization, manipulation,
navigation, and analysis of multivariate, time-varying volumetric
data, increasing the quantity and clarity of the information conveyed
from the visualization system.
