Hi,
in order to verify a system, I would like to create a freeform surface from a cloud of (parametric) points in order to subsequently apply a merit function and obtain an optimization.
Is it possible?
Thanks

Hi Luca,
OpticStudio provides a number of freeform surfaces. One of these is a Grid Sag Surface. There is an article on it here.
In the article you will see that a data file is used to define the surface sag. It requires z values on a regular xy grid. A tool such as Mathematica, Matlab, or Python could be used to create a file of the required format, reinterpolating the data if necessary.

Hi Luca,
I was going through a few posts from April and came across this one. In addition to David’s suggestion, I wanted to let you know that the TrueFreeForm surface may perform the steps you’re after. You can read more about it here: Using the TrueFreeForm surface for grid based freeform optimization – Knowledgebase (zemax.com)
Note: This surface type is only available to Premium subscription license-holders. If you want to give it a try, email sales@zemax.com and they may be able to set you up with a temporary trial.
