A method for solving the problem of surface/surface intersection in su
ggested. This method uses an adaptive subdivision and a facetted model
based on triangles. A bounding box and a different dividing method ar
e newly developed. Instead of the calculation of the characteristic po
ints, a new linking technique is developed. This method solves the int
ersection problem between bicubic or higher grade surfaces. The desire
d calculation-precision is specified by the input parameter.
