Jerzy, I really do not wish to get into an argument with you. This seems to happen every time you come onto this mailing list. If "winning" this argument is so important to you, then you may have it. I will not continue to split hairs with you.
Thank you for mentioning the concept of implicit surfaces and marching cubes. I am glad that is helpful to the original poster. Cheers!
