The application demo runs on windows and features a standard MFC multi
document-view architecture. It features a trackball to interactively
manipulate the polyhedron. Accepted mesh file formats are ASCII OFF
and OBJ (1-based vertex indices for the latter). \\

\noindent {\bf Main keys}\\
Press 's' to subdivide the mesh using the quad-triangle scheme.\\
Press 'r' to choose a rendering mode. Note that superimposing the
control edges during subdivision is only available for the
quad-triangle subdivision scheme.\\ Press 'ctrl+c' to generate a
24-bits raster image output to the clipboard.\\

\noindent {\bf Compiling on Windows}\\
The application has been compiled on MS .NET 2003 using CGAL. Apply
the following steps to compile the demo:
\begin{itemize}
\item Install the last release of CGAL.
\item Define an environment variable CGALROOT with the path to the
CGAL folder. If you installed CGAL with the standard wizard installation, the CGALROOT variable was defined at that time.
\item Compile the CGAL library in multithread mode. Go in CGALROOT/src directory and open the cgallib project. Open from the main menu, Project Properties. Go to C/C++, Code Generation, Runtime Library and choose Multi-threaded Debug (/MTd). Go to Librarian, General, Output File and modify to ../lib/msvc7/CGAL\_MT\_DEBUG.LIB. If you want to build in release mode, choose at the Project Properties Configuration Release, and do the same steps as before but at the Runtime Library you choose Multi-threaded (/MT) and in the output of Librarian put ../lib/msvc7/CGAL\_MT\_RELEASE.LIB.

To build debug and release mode, you need to choose the mode in the main menu Build at the Configuration manager.

\item Open the Mesh project in the tutorial/Polyhedron/MFC/Subdivision/ directory. Choose from the Configuration manager the mode (release or debug) you want to build your application and then go to the next step.
\item Rebuild all.
\end{itemize}
