What's the center of the object?
Don't bother trying to figure it out, there are many possible ways to
answer that question and none of them would help in computing smooth
normal vectors for anything but a sphere. His point was that there are
several algorithms for guessing the correct normals, and none of them
work all the time. For instance: take a deformed cube. Most smoothing
algorithms will mess up the sharp edges and corners, because the
algorithm doesn't "know" they are supposed to be sharp.

It isn't by anyone who knows what they are talking about.

As you say, checker and hexagon are *patterns*, not pigments. You are
confusing the two things.

Never be sorry for posts (unless they're unkind). In this case,
I guess you probably learned something. Its nothing to do
with stupidity, but just with knowledge and newbie (in this case
being newbie to meshes). These kind of posts become insightful
discussions sometimes, so no need to be unhappy.
Just my 2 cents to cheer you up...
Regards,
Tim

That has helped cheer me up! Thanks!
I am a newbie to meshes. I haven't used any meshes in my scenes yet, just
CSG objects and isosurfaces.
