Shell rendering: fast volume rendering and analysis of fuzzy surfaces
Jayaram K. Udupa, Dewey Odhner · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1992
We present a new paradigm, called shell rendering, for volume visualization of surfaces. It significantly overcomes the two major impediments of current volume rendering methods -- high computational cost and storage requirements -- and makes interactive volume rendering feasible in a workstation environment via portable software. It imparts the notion of a structure -- a shell -- to what is usually treated as an amorphous semi-transparent volume and makes morphometrics of surfaces feasible in the volume rendering paradigm.
