NAME

       glutInitDisplayMode - sets the initial display mode.

SYNTAX

       void glutInitDisplayMode(unsigned int mode);

ARGUMENTS

       mode	 Display mode, normally the bitwise {m OR}-ing of GLUT display mode bit masks.  See values below:

       GLUT_RGBA
	       Bit mask to select an RGBA mode window. This is the default if neither GLUT_RGBA nor GLUT_INDEX are specified.

       GLUT_RGB
	       An alias for GLUT_RGBA.

       GLUT_INDEX
	       Bit mask to select a color index mode window. This overrides GLUT_RGBA if it is also specified.

       GLUT_SINGLE
	       Bit mask to select a single buffered window. This is the default if neither GLUT_DOUBLE or GLUT_SINGLE are specified.

       GLUT_DOUBLE
	       Bit mask to select a double buffered window. This overrides GLUT_SINGLE if it is also specified.

       GLUT_ACCUM
	       Bit mask to select a window with an accumulation buffer.

       GLUT_ALPHA
	       Bit mask to select a window with an alpha component to the color buffer(s).

       GLUT_DEPTH
	       Bit mask to select a window with a depth buffer.

       GLUT_STENCIL
	       Bit mask to select a window with a stencil buffer.

       GLUT_MULTISAMPLE
	       Bit mask to select a window with multisampling support. If multisampling is not available, a non-multisampling window will automat-
	       ically be chosen. Note: both the OpenGL client-side and server-side implementations must support the GLX_SAMPLE_SGIS extension  for
	       multisampling to be available.

       GLUT_STEREO
	       Bit mask to select a stereo window.

       GLUT_LUMINANCE
	       Bit  mask to select a window with a ``luminance'' color model.  This model provides the functionality of OpenGL's RGBA color model,
	       but the green and blue components are not maintained in the frame buffer. Instead each pixel's red component  is  converted  to	an
	       index  between zero and glutGet(GLUT_WINDOW_COLORMAP_SIZE)-1 and looked up in a per-window color map to determine the color of pix-
	       els within the window. The initial colormap of GLUT_LUMINANCE windows is initialized to be a linear gray ramp, but can be  modified
	       with GLUT's colormap routines.

DESCRIPTION

       The initial display mode is used when creating top-level windows, subwindows, and overlays to determine the OpenGL display mode for the to-
       be-created window or overlay.

       Note that GLUT_RGBA selects the RGBA color model, but it does not request any bits of alpha (sometimes called an alpha buffer  or  destina-
       tion alpha) be allocated. To request alpha, specify GLUT_ALPHA. The same applies to GLUT_LUMINANCE.

       The glutInitDisplayString routine provides a more powerful way to select frame buffer capabilities for GLUT windows.

GLUT_LUMINANCE IMPLEMENTATION NOTES
       GLUT_LUMINANCE is not supported on most OpenGL platforms.
