OpenGL - Explain glutInitDisplayMode()

Explain in detail what functionality is provided by the settings in the line:

glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH);

so far i know that this line will initialize the display mode by requesting a double buffere setting, setting a RGBA window mode and request a depth buffer but how can i explain this more simply. i want to describe each argument in simple English

Solution 
  • glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH);

    glutInitDisplayMode - inits display mode

    GLUT_DOUBLE - allows for display on the double buffer window

    GLUT_RGBA - shows color (Red, green, blue) and an alpha

    GLUT_DEPTH - allows for depth buffer
