This is purely a semantic question and I mean in terms of 3D graphics, not math. (though perhaps there's no such distinction)
Or is this like asking if viruses are alive? (but please let's not have THAT discussion, hehe )
My thought is, as a point technically is a (graphics-) primitive, it is geometry, right? But as I might be completely wrong, I thought I'd come here and start a lively discussion about it.
