A method for generating two-variable 3D FDs directly from a striped li
ghting system is developed. An iterative algorithm is proposed to comp
ute the two-variable 3D FDs for both axisymmetric and nonaxisymmetric
objects and a formula for convergence test is derived. Experiments con
ducted for a set of 3D objects show that the iterative algorithm conve
rges very quickly and the two-variable 3D FD representations are attai
ned accurately.
