Abstract
The dramatic increase in the use of 3D image acquisition devices over the past decade has inspired major new developments in the display of volume data sets. In this chapter we present an overview of these diverse display methods and discuss the relative advantages and disadvantages of each of the different approaches. In addition, we touch upon some of the major issues involved in creating high-quality images from volume data, including the problems of surface definition and object segmentation. Due in part to the rapid, almost frantic, pace of recent developments in methods for rendering images from volume data, there has not yet emerged any widely accepted taxonomy for these methods. Because the human visual system is adapted for environments in which images of surfaces predominate, most algorithms emphasize in one way or another the display of surface-like information, either implicitly or explicitly. For clarity, we will avoid using the terms "surface rendering " and "volume rendering " to describe the various methods, since although prevalent in the literature they have no precise, commonly accepted definitions. Instead, we will differentiate the various rendering methods using the following three characteristics, which are somewhat more precise and, we hope, less misleading: 1) whether the explicit creation of an intermediate surface representation is required (if so,
