Thank you very much fr the reply. If you don't have something that reads
.ply files then what file format does CGAL read in terms of point cloud
files??
Thank again and waiting for your reply

CGAL is not a end-user software that accepts a certain type of files,
it's a library that has an API. For the case of the surface
reconstruction  package you need to provide points and normals as
documented here:

http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Surface_reconstruction_points_3_ref/Class_Poisson_reconstruction_function.html

The way you read points and normal from file is independent from the
algorithm (and simple to write for a file of point and normal whatever
file format you use).

Now if you want to try the demo, you can provide off files
or xyz file
(
which simply contains points if you don't know normals
x0 y0 z0
x1 y1 z1
...
xn yn zn)

or a pwn file
(which simply contains points and normals
x0 y0 z0 nx0 ny1 nz1
...
)

       Hi,
       Am new to CGAL Library and the documentation is very big and
       difficult
       to follow. I wanted to ask if someone can guide me how to read
       .ply file
       since I want to use CGAL to convert point cloud to mesh
       triangles. Any
       help or guide will be appreciated. Am using Microsoft visual
       studio 2010
       with win x64 bit OS.
       Thank you
       Candy


   You might be interested by this package:

   http://www.cgal.org/Manual/__latest/doc_html/cgal_manual/__Surface_reconstruction_points___3/Chapter_main.html

   <http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Surface_reconstruction_points_3/Chapter_main.html>

   For the  ply file format I don't think we have something to read them.

   Sebastien.
