17 deferred generic class CSFunction from IntImp
22 inherits FunctionSetWithDerivatives from math
24 ---Purpose: This class is the template function for the intersection
25 -- between a curve and a surface.
26 -- It is possible to implement such a function with an
28 -- - ZerCSParFunc for the intersection between a 3d curve
30 -- - ZerCOnSSParFunc for the intersection between a curve
31 -- on surface and another surface.
