NAME

     glutInitDisplayMode -- Set the window creation display mode.

LIBRARY

     OpenGLUT - window

SYNOPSIS

     #include <openglut.h>

     void
     glutInitDisplayMode(unsigned int displayMode);

PARAMETERS

      displayMode     Requested display mode bitmask.

DESCRIPTION

     glutInitDisplayMode() allows you to control the mode for subsequent OpenGLUT windows.

     Allowable	displayMode  is a combination of:

      -  GLUT_RGB
     Red, green, blue framebuffer.

      -  GLUT_RGBA
     Red, green, blue, alpha framebuffer.

      -  GLUT_INDEX
     Indexed color framebuffer.

      -  GLUT_SINGLE
     Single-buffered mode.

      -  GLUT_DOUBLE
     Double-buffered mode.

      -  GLUT_ACCUM
     Accumulation buffer.

      -  GLUT_ALPHA
     Alpha channel.

      -  GLUT_DEPTH
     Depth buffering.

      -  GLUT_STENCIL
     Stencil buffering.

      -  GLUT_MULTISAMPLE
     Multisampling mode. (not always available)

      -  GLUT_STEREO
     Left and right framebuffers.

      -  GLUT_LUMINANCE
     Greyscale color mode.

     Additionally, the following  experimental	 features are implemented:

      -  GLUT_OFFSCREEN
     Offscreen windows are very much like onscreen windows that have been dragged off of the edge of the screen.  The biggest issue is that off-
     screen windows do not support subwindows.	Other than that, onscreen windows that are dragged off of the edge may not store graphics that you
     render (while  GLUT_OFFSCREEN  windows do), and there is no way to drag an offscreen window onscreen for user interaction.

      -  GLUT_BORDERLESS
     Borderless windows are very experimental, and their precise behavior is not set in stone.	See also glutCreateMenuWindow().

     The following are	defaults  :

      -  GLUT_RGB
      -  GLUT_SINGLE

CAVEATS

     Some display mode features were introduced by OpenGLUT.

     Not all features or combinations of features are valid for all platforms.

     There is no way to change the display mode of an open window.

BUGS

      GLUT_OFFSCREEN  windows do not work with nVidia cards/drivers.  (Both Win32 and X11)

      GLUT_BORDERLESS  seems to vary by the window manager on X11, though twm (for example) performs very similarly to WIN32. But KDE's window
     manager (for example) does not let you send keystrokes to borderless windows without OpenGLUT hacks.

NAME

     glutInitDisplayString -- Set the window creation display mode.

LIBRARY

     OpenGLUT - window

SYNOPSIS

     #include <openglut.h>

     void
     glutInitDisplayString(const char *displayMode);

PARAMETERS

      displayMode     Requested display mode string.

DESCRIPTION

     glutInitDisplayString() permits you to define a display mode for subsequent windows that you open.  In most regards, control is at least as
     fine as with glutInitDisplaymode().

     The  displayMode  parameter is case-sensitive, and tokens are separated by ASCII TABs (	) and SPACEs.

      -  index
     Enables  GLUT_INDEX.

      -  luminance
     Enables  GLUT_LUMINANCE.	Enables  GLUT_STENCIL.

      -  red
     Number of red channel bits.

      -  green
     Number of green channel bits.

      -  blue
     Number of blue channel bits.

      -  alpha
     Number of alpha channel bits.  Enables  GLUT_ALPHA.

      -  rgb
     Number of	RGB  channel bits, no aplha bits.  Enables  GLUT_RGB.

      -  rgba
     Number of	RGBA  channel bits.  Enables  GLUT_RGBA.

      -  depth
     Number of depth buffer bits.

      -  stencil
     Number of stencil buffer bits.

      -  double
     Enables  GLUT_DOUBLE.

      -  single
     Enables  GLUT_SINGLE.

      -  stereo
     Enables  GLUT_STERO.

      -  acca
     Number of	RGBA  accumulation bits.  Enables  GLUT_ACCUM.

      -  acc
     Number of	RGB  accumulation bits.  Enables  GLUT_ACCUM.

      -  samples
     Number of samples for GLX's  SGIS_Multisample.   Enables  GLUT_MULTISAMPLE.

      -  buffer
     [TODO] Sets bits in index mode?

      -  conformant
     [TODO] Conformant with what?  Enables  GLUT_DEPTH.

      -  slow
     [TODO] Indicates if a frame-buffer is slow.

      -  num
     [TODO] Appears to select a frame-buffer configuration by number from an unspecified list.	Probably very non-portable.

     A special capability  name indicating where the value represents the Nth frame buffer configuration matching the description string

      -  xvisual

      -  xstaticcolor

      -  xpseudocolor
     X11 specific: "pseudocolor" mode.

      -  xtruecolor
     X11 specific: "trueolor" mode.

      -  xdirectcolor
     X11 specific: "directcolor" mode.

CAVEATS

     Conflicting modes, such as  single  and  double  have the same interaction as for glutInitDisplayMode().

TODO

      GLUT_BORDERLESS  and  GLUT_OFFSCREEN  are not represented.

     Not all features appear to be implemented.  In particular, numeric parameters and comparator specifications are lacking. See GLUT 3.7 sources
     for example.
