Ellipse parametric form from data.
what data am I looking for:
what data I have
semi-major/minor axis/radius. axes can be non-perpendicular and that's when I have trouble getting parametric form from data.
transformation applied is transformation from
x axis (1,0)
y axis (0,1)
origin ellipse center
x axis semi-major * major radius
y axis semi-minor * minor radius
ellipse is generated by drawing radius 1. circle at origin in source coordinate system and transforming result into destination.
I need to get parametric form (or major/minor axis/radius) in destination coordinate system from the above if possible.
sorry if I'm not clear, but engrish speaker here after few hours of thinking and googling for solution (Worried)
