Abstract

An automatic contour tiler (CTI) has been designed and implemented for use with planar, simple, possibly concave, nonintersecting `wireloop' contours which are typical in medical applications. Without user interaction or guidance, CTI connects 2D contours into 3D branching structures and then produces the tiles by extracting the surface of the resulting volume. CTI is a perturbing tiler based on Boissannat's method. Previous ideas are extended by offering implementation suggestions--above and beyond theoretical considerations--that result in a robust program even in the face of ill-formed contours. CTI is one of a suite of tools written to a NCI standard. This results in very portable code and makes it practical and economical to produce portable tools regardless of the site's local data formats.
