    0. Introduction
    
    Thank you for downloading and using the OpenVolumeMesh library. OpenVolumeMesh
    is a generic data structure for the comfortable handling of arbitrary
    polyhedral meshes. Its concepts are closely related to OpenMesh
    <http://www.openmesh.org>. In particular, OpenVolumeMesh carries the general
    idea of storing edges as so-called (directed) half-edges over to the face
    definitions. So, faces are split up into so-called half-faces having opposing
    orientations. Furthermore, in OpenVolumeMesh the data is arranged in a top-down
    hierarchy, meaning that each entity of dimension n is defined through a
    (ordered) tuple of entities of dimension (n-1). These are the intrinsic
    adjacency relations of the volumentric meshes. One can additionally compute
    bottom-up adjacencies which means that for each entity of dimension n, we also
    store its local adjacencies to entities of dimension (n+1). These adjacency
    relations have to be computed explicitly which can be performed in linear time
    complexity. Both adjacency relations, the top-down and the bottom-up
    adjacencies, are used to provide a set of iterators and circulators that are
    comfortable in use. As in OpenMesh, OpenVolumeMesh provides an entirely generic
    underlying property system that allows attaching properties of any kind to the
    entities. In order to learn more about the implementational details of
    OpenVolumeMesh, please refer to the only documentation which is available
    at <http://openvolumemesh.org/Documentation/OpenVolumeMesh-Doc-Latest>.
    
    OpenVolumeMesh is entirely written in C++ making heavy use of the
    standard template library as well as template programming paradigms.
    Although OpenVolumeMesh has been developed to the best of my knowledge,
    it does not claim to be free from defects nor does it raises the claim to
    have inveterate underlying implemented concepts. So, any ambitious developer
    is invited to participate in the development process to make OpenVolumeMesh
    a well-working, reliable, and useful library. Please feel free to commit
    suggestions, bug reports, or patches to the OpenVolumeMesh project management
    system (redmine), which you find at
    
    <http://www.openvolumemesh.org/redmine/projects/openvolumemesh>,
    
    or you can send them directly to my e-mail address which is
    
    <mkremer@cs.rwth-aachen.de>.
    
    =========================================================================== 
    
    1. System Requirements
    
    OpenVolumeMesh is shipped as source project and can be built on all common
    architectures and operating systems including:
    
    - Windows XP/2000/Vista/7 with Visual Studio 2008 SP1 or Visual Studio 2010.
    
    - MacOSX 10.6. with XCode 4.3
    
    - Linux with GCC 4.5 and higher
    
    Note that OpenVolumeMesh uses CMake as build system, so make sure that
    the latest version of CMake is installed on your computer. Download
    CMake under <http://www.cmake.org>.
    
    Note also that, in order to build the documentation, you will need to
    have Doxygen installed on your computer. Download Doxygen under
    <http://www.doxygen.org>. The use of Doxygen is not mandatory though.
    
    =========================================================================== 
    
    2. Building OpenVolumeMesh
    
    OpenVolumeMesh is equipped with a CMake build system <http://www.cmake.org>.
    Make sure that at least version 2.6 of CMake is installed on your computer.
    Once CMake is installed, perform the following steps (on Linux, Mac OSX):
    
    - Create a build directory somewhere outside the source directory
      of OpenVolumeMesh. Name it e.g. "OVM-build-release", or whatever
      name might be suitable.
    
    - Change into the recently created directory and type
      "cmake /path/to/OpenVolumeMesh/sources".
    
    - If you want to change the build configuration, say from debug to release,
      type "ccmake .". Note that unless not explicitly specified otherwise, CMake
      sets the build configuration such that it will be built with debug flags on.
    
    - Once everything is configured to your satisfaction, type "make" followed
      by "sudo make install" in order to build and install the library.
    
    On Windows, start the CMake gui tool and set the path to OpenVolumeMesh's
    sources. Then select the target project type (Visual Studio 2008, 2010)
    and click on "Configure". Once everything is configured to your satisfaction,
    click on "Generate". You will now find a Visual Studio project file
    in the specified build folder (which is "Build" per default). Open this
    file in Visual Studio and select "Build all".
