Perhaps he should have used the word "projection", or "cross-section". I understood it, at least.
Viewed from the image A projection point you will see half of image B if it's projected on a sphere or cylinder.
And if it was neither a sphere nor a cylinder, but a shape designed to catch shadows in a very specific way, you get a different result.
I won't even bother trying to explain why the other two are bullshit, his knowledge of optics is obviously zero.
The other two work as well. The sculptures are not cylinders, the circles indicate "insert sculpture here".
