> Comparing to Potrace which only accept binarized inputs (Black & White pixmap), VTracer has an image processing pipeline which can handle colored high resolution scans. tl;dr: Potrace uses a O(n^2) fitting algorithm, whereas vtracer is entirely O(n). What is the Big-O of the algorithm with Segment Anything or other segmentation approaches? Potrace: https://en.wikipedia.org/wiki/Potrace https://en.wikipedia.org/wiki/Potrace The Ctrl-L to Simplify Inkscape feature attempts to describe the same path with fewer points/bezier curves. Could this approach also help with 3d digitization?
