Abstract

A method for rapid rendering of a desired line in a volumetric display having a rotatable screen includes stepping the rotatable screen through a sequence of angular positions and, at each angular position, rendering, on the rotatable screen, a rasterized approximation of a line segment containing an intersection of the desired line and the rotatable screen.
