Abstract
This paper presents some novel interface techniques for the
visualization of scalar field data in virtual reality environments. In
particular, we discuss the direct manipulation of isosurfaces and cutting
planes and give general guidelines for design of user interfaces and
algorithms for scientific visualization in virtual environments. This
work was motivated by the need to visualize scalar field data from
computation fluid dynamics calculations interactively in the Virtual
Wind Tunnel at NASA Ames, but the techniques are applicable to
other problem areas, including medical imaging and geological
and mathematical visualization.
