Easy3D-v2.5.2

Changes:

• unified naming for classes, namespaces, and files
• simplified initialization
• changes in the names of a few files and namespaces (see the breaking changes below)

Breaking changes:

• the file version.h/version.cpp and thus the following functions have been moved to the util module:
  • easy3d::version_major()
  • easy3d::version_minor()
  • easy3d::version_patch()
  • easy3d::version()
• the following namespaces have been renamed:
  • buffers -> buffer
  • shapes -> shape
• the following files have been renamed:
  • buffers.h/buffers.cpp -> buffer.h/buffer.cpp
  • shapes.h/shapes.cpp -> shape.h/shape.cpp
• the following function has been moved to namespace easy3d::geom (see here):

  bool intersect(const GenericPlane<FT> &plane1, const GenericPlane<FT> &plane2, const GenericPlane<FT> &plane3,
                      typename GenericPlane<FT>::Point3 &point);
