- 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 mul-
tisampling is not available, a non-multisampling window will
automatically 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 pixels 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, sub-
windows, 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 destination 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.
Notes sur l'implémentation de GLUT_LUMINANCE
GLUT_LUMINANCE is not supported on most OpenGL platforms.
