Hi,

In order to install CGAL, I downloaded CGAL setup.exe and CMAKE.exe.
First i installed CGAL and then the CMAKE GUI. Then in order to
configure CGAL, I started the CMAKE and click on configure and
select the generator as Visual 10 (i have visual C++ 2010). In
CMAKE, What specific files i have to chose on 'Browse Source"
and 'Browse Build" before click on Configuration?
Please help.

Brian.


I guess you need to select the CMakeLists.txt in at the root of the CGAL
directory.


Did you tried the pre-compiled demo as I suggested:

Hi,

Suppose i have a list of ten points in a text file.
I want to create a voronoi diagram of these
points. How van i do it? I am new to CGAL
and please help. I use MS Visual C++ for
programming. I can read the point coordinates
from the file.

Brian.


You can use the Delaunay_triangulation_2 demo.

Sources in the CGAL tarball are here
CGAL-3.8/demo/Triangulation_2.
In addition, on windows a precompiled demo is available here:
http://www.cgal.org/demo/3.8/delaunay_triangulation_2.zip

The format for input points is
x1 y1
x2 y2
x3 y3
