Hi

If I have an ellipse like this (not very good) illustration below. I know the length of the major & minor axis's, I know the distance between A and B, A and C, etc. The angle of the red lines will always be 90 degrees.

Could someone tell me the formula for calculating points on the ellipse for the red lines?

Ultimately, I want to programmatically draw segments of the ellipse like in the second image. I figure I can do this using bezier curves once I know how to work out points on an ellipse.

Thanks
