Abstract
The ray effect in ray tracing method was analyzed and three new ray em itting methods for a surface element (method A, B and C) were presente d. Numerical computations of viewfactors for three different typical c onfigurations indicated that the proposed methods can significantly el iminate the ray effect. Compared with the conventional ray emitting me thod, the proposed methods, especially method C, can give much higher accuracy with less computer cost. In addition, the new method may have much wider range of applications. (C) 1997 Elsevier Science Ltd.
