Directx

What is DirectX?




  • Owned by Microsoft.
  • Created in 1995.
  • contains a set of librairies Direct3D, DirectInput and DirectSound .. DirectX box (XBox)

Why Does Everyone Use DirectX?


  • On Windows, DirectX graphics drivers are better maintained than the OpenGL graphics drivers
  • Game developers get less bug reports
  • Microsoft initiated a fear, uncertainty, and doubt (FUD) campaign against OpenGL around the release of Windows Vista, giving the impression that Windows Vista would remove support for OpenGL
  • Misleading Marketing Campaigns on the jump from DirectX9 to DirectX10, they only tweaked the config file making people believe that it was an enormous change


Why should we use OpenGL?


  • It is more powerful than DirectX
    • has a faster draw calls
    • direct access to all new graphics features (The tesselation technology that Microsoft is heavily promoting for DirectX 11 has been an OpenGL extension for three years)
  • Cross-platform
    • Even on windows the latest DirectX versions are not supported in Windows XP (1/2 of windows users have XP)
  • Microsoft monopoly (means no competition) on gaming would be very bad for both gamers and game developers.
