To use more precise language: There exists a direction from which the
highlight line on the model appears to have a corner (highlight has a
discontinuity in its derivative). This is visible in the photo I posted in
my other message.

I generated my patch like this:
Q = cornerPatchCP([0,0,0],1.5, 0.3);
using the cornerPatchCP that you previously posted. I was comparing this
patch to the patch you originally posted, so the length of d disagrees, I
think. I can change the patch, but for print test a larger curve is better.
