AnonSubmitter85, thanks for the feedback. I guess I have some tutorials to read. Actually I was hoping that there would be a very simple mathematical (non signal-processing) calcualtion but I guess that is not the case?

comment rotating parabolas in 3D to get part of a circle
So how about the first part of the question: how do you find the center and the radius of that circle? (I edited the second part out because it was confusing).

Another way to see the clip is on this link from Geogebratube, but that requires you to install the app into your browser / computer.

Yes, it is a perspective projection.

Yes, the view-point in 3D space, and the radius of that circle after rotating back parallel to the XY-plane.
