Computer Simulation of Goniophotometric Curves for Fabrics

Abstract

A previous paper '' described the simulation of specular reflected light curves by use of a fabric model. The simulation treated the case of a parallel light flux projected perpendicular to the filament axis in the fabric, and the model consisted of fine elliptic columns arranged side by side on the surface of an elliptic cylinder.In the present paper, the authors present a computer simulation of specular rerected light curves in which a parallel light flux is applied parallel to the filament axis of the fabric, using a new filament model. The new model consists of a number of thin elliptic cylinders of various minor axis lengths. Distribution of the minor axis length obeys two different rules: elliptic distribution, and normal distribution.As with the method described in a previous paper,1'' the present study aims to simulate the specular reflection curves of fabrics.
