Direct Volume Rendering Methods for Cell Structures

open access: yesScanning, 2012
SummaryThe study of the complicated architecture of cell space structures is an important problem in biology and medical research. Optical cuts of cells produced by confocal microscopes enable two‐dimensional (2D) and three‐dimensional (3D) reconstructions of observed cells.

An Overview of Rendering from Volume Data --- including Surface and Volume Rendering [PDF]

open access: yes, 1993
Volume rendering is a title often ambiguously used in science. One meaning often quoted is: `to render any three volume dimensional data set'; however, within this categorisation `surface rendering'' is contained.
