Abstract

We have developed a three-dimensional display algorithm for discrete objects in a discrete space. Objects may be concave or convex, have holes (including interior holes) and can consist of disjoint parts. The input for our algorithm is a binary scene derived from a consecutive set of segmented and interpolated computed tomography (CT) cross-sections. The output is a shaded three-dimensional appearance of an organ from a user specified viewing direction.
