CommonMistakes

Common mistakes

This article presents most common mistakes of users of this library.

Main

• Creation of OpenGL context before using any of OpenGL functionality

  • Result: crash (mostly on initialization/startup)
  • Cause: OpenGL context is not created default.
  • Solution: You have to create Window object and use it's create() method, which will initialize internally used libraries (GLFW, GLEW).
  • Alternative solution: You could create hidden context. See this guide.

• Initialization of libraries before using library's modules

  • Result: mostly crash
  • Cause: Some of library's modules (like ones system-dependant) use internally GLFW library.
  • Solution: You have to initialize GLFW by creating Window (check above).
  • Alternative solution: You could use Window::initializeGLFW() static method without creating any windows.

OpenGL related

• No auto-binding (yet)
  • Result: Incorrect work of program
  • Cause: No binding buffers/textures/program/etc. before usage. Fow now, library does not bind it's object before usage of it not to slow down whole program.
  • Solution: You have to ensure that proper object are binded/used.
  • Additional notes:
    • This feature (auto-binding and context management) may be implemented in future, but it's not implemented yet.
