Method of constructing three-dimensional image such as three-dimensional image obtained when internal parts are observed through a hole

摘要

A method of constructing a three-dimensional image by using a central projection method, in which a predetermined region containing a point of view is set in advance, and in the case of performing coordinate transformation by the central projection method and shading, the coordinate transformation and shading are applied not to coordinates of pixels within said region but to coordinates of pixels out of said region.
