NAME [Toc]

 RGBmode - sets a rendering	and display mode that bypasses the color map

C SPECIFICATION [Toc]

 void RGBmode()

PARAMETERS [Toc]

 none

DESCRIPTION [Toc]

 RGBmode instructs the system to treat color as a 4-component entity in
 the currently active drawmode. Currently RGB mode	is supported only by
 the normal	framebuffer, so	RGBmode	should be called only while in draw
 mode NORMALDRAW. You must	call gconfig for RGBmode to take effect.
 While in RGB mode,	a framebuffer is configured to store separate color
 values for	red, green, blue, and alpha components.	 Lighting, shading,
 and fog calculations are done in the true,	RGB color space. Colors and
 writemasks	must be	specified using	RGB-compatible commands	such as	c,
 cpack, and	wmpack.	 The red, green, and blue components stored in the
 framebuffer are used (after correction for	monitor	non-linearity) to
 directly control the color	guns of	the monitor.
 Many advanced rendering features, such as complex lighting	models,
 texture mapping, polygon antialiasing, and	fog, are available only	in RGB
 mode.

SEE ALSO [Toc]

 c,	cmode, cpack, gammaramp, gconfig, getdisplaymode, getgdesc, wmpack

NOTE [Toc]

 RGBmode is	not supported on all hardware configurations. The command
 getgdesc can be used to determine how many	bitplanes in the normal
 framebuffer are available for each	color component	in both	single and
 double buffered RGB mode.
 This routine is available only in immediate mode.
