Object shape expression apparatus

摘要: The object shape expression apparatus includes a surface data producing unit which produces three dimensional coordinate of the by impinging slit light on object. A orientation calculation means calculates tilted angle normal lines extended from said defined data. An area dividing divides into plurality sets such that included in each are within predetermined range. Each thus obtained represents single areas conforming surface. plane patch generator generates flat or curved patches for to form model representing Since is divided based thereof, portion changing its configuration greater expressed more areas.
