Detailed Description

This implicit function is the maximum of two (of more) implicit functions with which it is constructed. This results in an implicit function whose interior is the intersection of the interiors of the given implicit functions. For the maximum, it uses the smooth absolute value Ae(a,b) |a-b| max(a,b) = 0.5*(a+b + | a-b |)
