FL-Essentials

FL-Essentials (FLE) is a FLTK based software system which provides extreme easiness in building (responsive) GUI applications. It consists of C++ class library and gives thread-safe image processing support for OpenCV. It also provides OpenGL based 3D classes to create computer graphics applications with fully featured GUI.

Repository structure

FLE Library is implemented in C++ (but provides both a C and a C++ish interface). The directory structure is:

• /examples (Examples to illustrate possible use cases for FLE)
• /include/FLE (Public header C and C++ header files)
  
• /include/FLE/Math (Classes for 3D math and OpenGL programming)
• /lib (Prebuild static libraries for VS2017)
  
• /src (Source code)
  
• /extras (useful material to create an application)
  

Building

Take a look into the INSTALL file. The build system is CMake, if you already used CMake before there is a good chance you know what to do.

Video tutorial that explains the build procedure using CMake (three libraries OpenCV, FLTK, and FLE are compiled in this video):

Required Libraries

• FLTK >= 1.4.x
• OpenCV >= 2.x.x
