long back someone posted a code to make the below model. [image: Screenshot 2023-10-07 at 7.36.13 PM.png] I don't remember the great guy's name. I wrote a python version of the same a year or so ago. Whenever I have to test the efficiency of an offset function, I run on this model. earlier it used to take around an hour just to calculate the points to produce this, rendering time is separate. I have written an offset function (named oset) which calculates this model in 1 minute, which I feel is a huge improvement over the past. Although this offset function does not work if the inner offset amount given is bigger than a certain amount or very large on a few shapes, it still works in most of the cases. The python version of the code to make this model is attached here in case anyone is interested.
