Hex-quad

Change-hex-quad

Modifying constructor for hex-quad structures.

Syntax

(change-hex-quad x 
                 [:1st <1st>] 
                 [:2nd <2nd>] 
                 [:3rd <3rd>] 
                 [:4th <4th>])

This is an often useful alternative to make-hex-quad.

We construct a new hex-quad structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.
