I bet I know what it is. This is the place in the code where we use
Point3i pt0 = new Point3i()
Point3i pt = new Point3i(pt0)
I bet it's a Java versioning problem. I bet the Point3i class file we are
using does not have the initializer:
Point3i(Point3i pt);
and in PC versions, Java has that natively, but in the Mac version Java
does not.

If nature does not answer first what we want,
it is better to take what answer we get.
