  • A CONTRIBUTING.md file has been added to describe how to contribute
    to the library. (David Coeurjolly,
    #1112)
  • DGtal requires now to have a C++11 enabled compiler (gcc>4.6,
    clang>2.9, VS14, ...). This allows us to use new C++11 features in
    DGtal core and to have more generic and reliable code. (David
    Coeurjolly, #1080)
  • DGtal core now compiles on Microsoft Windows, Visual Studio (only
    VS14 or above). Many issues have been fixed for compatibility with
    'cl' compiler. (David Coeurjolly, Jérémy Levallois,
    #1074)
  • DGtal with QGLViewer option activated now compiles on Microsoft Windows,
    Visual Studio (only VS14 or above). (Bertrand Kerautret,

    #1075)

    #1081)
  • New possibility to move the light source direction using the mouse move
    in Viewer3D (with the key SHIFT+CTRL (SHIFT+CMD on mac)). The light source
    direction is now defined according the main coordinate system (no more from
    the camera center).
    (Bertrand Kerautret #1070)
  • Adding raw I/O capabilities for non integral types and signed integers.
