comment How do I find a Bezier curve that goes through a series of points?
The design guys are not the problem. The problem is that nearly every 3D CAD package stores curves in its own proprietary binary 3D file format. They are happy to "export" their designs to some other format, but apparently their only choices are (a) some other proprietary binary file format, or (b) a STL made of thousands of tiny flat triangle facets.

comment Can prefix code always achieve optimal data compression?
@MJD: I think what he's asking is: Does there exist a character code that gives better compression than any prefix code? A proof that, among all possible prefix codes, Huffman is optimal, doesn't resolve this question one way or the other.

revised Is this valid parametric equation to create control points for a helix in 3D space?
I'm guessing setting x to two different things was a typo; perhaps you meant z ?

@ChuckFernández: I think that was a simple typo; fixed now.
