Thank you for your code, I was able to improve my curve rendering at the expense of your code and achieve high performance when thickening curves) But you should think about it to improve your algorithm) I have attached the source code of the test application on the basis of which I was trying to improve the drawing of curves) It is written in C# in Visual Studio 2022)
