Hi,(adsbygoogle = window.adsbygoogle || []).push({});

Let's say I have a flat circle on the x-y axes, and I am looking at it from along the z-axis.

now let's say I rotate it along the x-axis by A(alpha) degrees, and take a 2D picture, I would receive an ellipse, right?

now let's say I would like to have a function from an angle T(theta), which gives me a point on the original flat circle, to an angle G(gama), which gives me a point on the projected ellipse.

Anyone?
