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.
