Deform an ellipse to an irregualar shape in grasshopper

Capture 2

Hi everyone, I was doing some test in grasshopper try to deform an ellipse to an irregualar shape, I tried sporph, but the ellipse came out of the shape I got. Just want to ask is it possible to deform an ellipse to the shape I got. the second image is what I want to achieve.

My guess is that your source and target surfaces are not both untrimmed. Also, an ellipse only has 9 control points which doesn’t make it very “flexible” for mapping, which is why I rebuilt it with 20. This is worth remembering if you’re dealing with more complicated curves and non-planar surfaces too.
