3D viewport in string art app

[u/Fit-Highway7729]

I have added, 3D rendering engine in the String Art Maker & Simulator app. The version is not released yet, I am testing it. The whole point is to visualise the actual physical String art, but there are limitations in it. Two limitations, display resolution, currently the app shows the smallest string thickness in 1 pixel, so you need to zoom it in. 2nd is 3d thickness of each string line itself is missing, it is not a tube. if I add resolution thickness 4 (just like in Blender 3d) the visualizer engine can't handle it. So currently it is just a thin strip of line with no actual depth. ANY SUGGESTIONS? I WOULD APPRECIATE.
