wglinfo - command line tool printing OpenGL information

wglinfo is a diagnostic tool printing information about OpenGL library on Windows system in a similar way as glxinfo does the job on Linux. In case, if libEGL.dll (e.g. Angle or another implementation) is in PATH, it also prints information about EGL/GLES.

The output includes:

• Platform (EGL, WGL, GLX, CGL)
  • Vendor, version and extensions list
• OpenGL context (Compatibility and Core profiles).
  • Vendor, version, extensions list and API limits.
• OpenGL ES context.
  • Vendor, version, extensions list and API limits.
• List of visuals.

Supported platforms:

• WGL (Windows)
  • OpenGL Compatibility Profile.
  • OpenGL Core Profile (WGL_CONTEXT_CORE_PROFILE_BIT_ARB).
  • OpenGL Software implementation (WGL_NO_ACCELERATION_ARB).
  • OpenGL ES context information (WGL_CONTEXT_ES_PROFILE_BIT_EXT).
• GLX (Linux)
  • OpenGL Compatibility Profile.
  • OpenGL Core Profile (GLX_CONTEXT_CORE_PROFILE_BIT_ARB).
  • OpenGL Software implementation (LIBGL_ALWAYS_SOFTWARE=1).
• CGL (macOS)
  • OpenGL Compatibility Profile.
  • OpenGL Core Profile (NSOpenGLPFAOpenGLProfile -> NSOpenGLProfileVersion3_2Core).
  • OpenGL Software implementation (NSOpenGLPFARendererID -> kCGLRendererGenericFloatID).
• EGL (cross-platform)
  • OpenGL Compatibility Profile.
  • OpenGL Core Profile (EGL_CONTEXT_OPENGL_CORE_PROFILE_BIT).
  • OpenGL Software implementation (LIBGL_ALWAYS_SOFTWARE=1).
  • OpenGL ES context information (EGL_OPENGL_ES2_BIT, EGL_OPENGL_ES3_BIT).
