What I want to show is the following picture, showing the feeling of many ovals stacked together.
However, I can only draw an ellipse according to the ellipse formula!
Don't know what to do next,Like rotating an ellipse.

How are you generating the points for the ellipse that you know how to draw? Simply rotating those points properly will get you the result. E.g., with a rotation matrix or you could use complex arithmetic to get the same result.
