After much study and failed transformations, Table 1 is finally turned into a node, to produce the gyroid boundary patch from pre-fundamental patch P0 to P1.
P1 transforms into P2, and the remaining 10 patches. Must write it up. I think clockwise 90 degree rotations and ccw 90 degree rotations are inconsistant with respect to x, y, and z axes and +/- 90 degrees?
It also helps to think in terms of world axes.
