Techniques for the interactive visualization of volumetric data

Abstract

Some ideas and techniques for visualizing volumetric data are introduced. The methods presented are different from both the volume rendering techniques and surface contour methods. Volumetric data is data with a domain of three independent variables. The independent variables do not have to indicate a position in space and can be abstract in the sense that they can represent any quantity. The authors cover only the case where the dependent data is a single scalar. The authors describe a collection of techniques and ideas for graphing cuberille grid data. All of these techniques are quite simple and rather easy to implement. During the development of these techniques, the authors were particularly concerned with allowing the user to interact with the system in order to interrogate and analyze the relationships indicated by the volumetric data.<>
