The plane passes through the point P, the origin by default, with the nonzero 3-element normal N. mirror (S, [1, 0, 0]) reflects in the yz plane. A reflection turns a right-handed part into its left-handed twin; the result is a valid solid of the same volume.

The solids keep their colours.

 ## An L-shaped bracket and its mirror image, joined into one part
 L = union (solid.box (30, 10, 5), solid.box (5, 10, 20));
 S = union (L, mirror (L, [1, 0, 0]));
 bbox (S)
 ⇒ -30   0   0   30   10   20
