Abstract: Aiming at parallel light,a new method for computing radiative transfer coefficient between complex surfaces is developed.And some disadvantages possessed by Monte-Carlo method are gotten over,such as more computational time and lower computational accuracy.The new method is analyzed and compared from respect to the computational time and accuracy,and results show that the new method is superior over Monte-Carlo method
