Errata for paper and PhD thesis Surface reconstruction from unorganized points
In the SIGGRAPH 1992 paper, on page 74, the third line of the signed
distance function definition should read:
z = p - ((p - o_i) . n_i) n_i
z = o_i - ((p - o_i) . n_i) n_i
The same correction also applies to the signed distance function
definition on page 28 of my PhD thesis.
