const N_LSE: usize = 8;Expand description
Number of points for least-squares fit and error evaluation.
This value is a tradeoff between accuracy and performance. The main risk in it being to small is under-sampling the error and thus letting excessive error slip through. That said, the “arc drawing” approach is designed to be robust and not generate approximate results with narrow error peaks, even in near-cusp “J” shape curves.
