Hi!

I have processed very small lidar point cloud (~ 1/4 million [classified]
points, see attached kylmaoja-xyzc-3Dview.png) according to chapters "Chapter 
54
Point Set Processing" and "Chapter 45 Surface Reconstruction from Point Sets"
(CGAL 3.5 manuals).

To my very BIG surprise, I get half ball feature under point cloud (see
mesh800-boundary-pic1.png), even when I am using
CGAL::Manifold_with_boundary_tag(). Would some other combination of parameters
for CGAL::make_surface_mesh() [or any other function] prevent such unwanted
features in mesh generation??

I am using CGAL 3.5.1-1 (Ubuntu 10.04).

What else [from CGAL] would be suggested for surface mesh generation (with
different level-of-details) of classified point clouds?

Thx,
