Abstract:
A method of deriving intermediate data representing a region, for at least a portion of a three-dimensional object, intermediate to spaced cross-sectional data descriptive of the three-dimensional object, comprising the steps of:supplying first data representative of a first cross-section;supplying second data representative of a second cross-section adjacent to said first cross-section;supplying third data representative of a third cross-section adjacent to said second cross-section;deriving first outward-facing data including comparing the first and second data;deriving second outward-facing data including comparing the second and third data;determining which portions of the first outward-facing data have a common boundary with the second outward facing data; andderiving intermediate data for a region between the first and second cross-sections or between the second and third cross-sections using said portions of at least one of said first or second outward-facing data having a common boundary.
