This is the code for Flipping-based iterative surface reconstruction for unoriented points.(GMP2024,CAGD)

flipping flag 1 should be: \begin{align}\label{00} \overline{\sigma}^{(1)}{\bm{p}{j},K}=\begin{cases} -1, & \overline{\chi}{K}(\bm{p}{j}^{+})>\overline{\chi}{K}(\bm{p}{j}) > \overline{\chi}{K}(\bm{p}{j}^{-}), \ 1, & \text{others}, \end{cases} \end{align}

which may be a writing mistake in the paper.
