摘要
Abstract
In this paper,an improved GRECO method applying to near field is proposed,the formula of the near field GRECO method is deduced.Based on the formula and the available GRECO method,the im-proved GRECO method sets the light model to position lighting in the OpenGL.By the setting,the illuminat-ed region changed with the distance between source and target is obtained.Meanwhile,the distance between the source and the element of surface is obtained by two times lighting with different coefficients of the attenu-ation factor.Numerical results for a square plate,a sphere,and a decoy are presented to demonstrate the effi-ciency and accuracy of this calculation method in the near field.关键词
