Roundness / circularity

[[be...]]

Hello,

I would like to visualise the deformation of circles on plastic bottles. I have two questions:

1. From a closed curve, how do I manage to create a colorimetric inspection that give me the distance from its barycenter to any point of the curve, like below ?

 

2. is it possible to artificially increase the points ajustment, in a purely visual approch ?

 

Thank you.

Does this help?
