Implementation of Divide Technique for Surface Intersection

Although the divide method For intersection of two surfaces has been used popularly, there still remains a problem of numerical calculation accuracy to be solved. By many experiments it is pointed out that any kinds of wrong results in divide step or intersection step are caused by the calculation accuracy. Some efforts made by the author for implementing the divide method are described. But finally it is concluded that the life of the divide method for surface intersection would be influenced if the accuracy problem were not be solved completely.
