Abstract
The present invention is a method of measuring a gonio-spectral reflectance factor to establish a gonio-spectral reflectance factor database available for a personal computer by which a highly-fine realistic 3D computer graphics image can be formed. The method enables colorimetry in a reduced hours in fewer viewing directions compared to the conventional method by executing colorimetry in a plurality of viewing directions selected at random from all the directions that can be viewed by a goniospectrophotometer, said plurality of viewing directions being less than all the directions that can be viewed by the goniospectrophotometer.
