  Offset surface  
From: Mike Horvath

Analogous to "parallel curve", but in three dimensions.

https://en.wikipedia.org/wiki/Parallel_curve

What formula could I use to generate an "offset surface" for an 
ellipsoid/spheroid? (An ellipse rotated around a vertical axis.)

Would a parametric function or implicit function be better or faster or 
simpler?

Thanks.


Mike
