- The Surface_mesher distance parameter is set to 0.005 for APSS (0.002 for Poisson). Both values are editable in the Options dialog.
- Removed the "APPS projection error" field in the Options dialog (unused).
- APSS kd-tree contains Point_with_normal_3 points instead of Gyroviz_point_3 objects (faster copy constructor).
- The number of neighbors is 7 by default (was 10).
- APSS caches the previous nearest neighbor to speed up the isValid() method (test if close to surface).
- If point is far from surface, APSS computes only the nearest neighbor (used to compute twice K nearest neighbors).
Fixed bug in bounding sphere computation.
Deleted ApssOracle.
Renamed class APSS as APSS_implicit_function.
Code cleaning: store normals in Vector_3 objects instead of Point_3.
