ABSTRACT:
Disclosed herein are a method for generating volume data from images of an object viewed from diverse view points. This method comprises the steps of: (a) in each of discrete coordinate positions within a coordinate system for rendering a volume, obtaining a value corresponding to the distance to the boundary of a viewed volume defined by the contour of the image of said object and by the point of view of said image; and (b) in each of said coordinate positions, on the basis of a plurality of said values obtained for said images of said object, determining a value corresponding to the distance to the object surface and then maintaining said value in a manner corresponded to said coordinate position. In the method, multi-valued data can be assigned to each vertex or lattice point, and therefore, a small number of voxels can represent precisely the three-dimensional shape.
