"There is a great satisfaction in building good tools for other people to use."
Freeman Dyson (b. 1923); British-born u.S. physicist, author.

NONE OF THIS IS REQUIRED - just desired.

I'm interested in where and how XlXtrFun is used, so the first two fields are (almost) required.
No information you give me will ever be given to anyone else.


I realize that you may not know exactly what you will use XlXtrFun for,
but what do you hope it will do for you?
This is important because it helps me direct my future development efforts.
Also, the only reward I get is hearing from people who are proud of what they are doing.

None of the following is even almost required, but If you don't mind, please tell me more.
(Of course, none of this will ever be sent to anyone else, I am just curious.)

Personal Web Page
Email Address (so I can send you free updates)
City in Which You Work
State, Province, or Prefecture
Zip/Postal Code (to distinguish like-named cities)
Company Web Page

Note: 3-D Interpolation from ordered input data is part of XlXtrFun. Surface Generation from Scattered Input Data is now released and included in the zip file. Feel free to with any questions regarding using these routines.
