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 - oi) · ni) ni
instead of
   z = oi - ((p - oi) · ni) ni

The same correction also applies to the signed distance function definition on page 28 of my PhD thesis.
