NAME    [Toc]    [Back]

     leftbuffer, rightbuffer - enables and disables drawing to the left/right
     buffer

C SPECIFICATION    [Toc]    [Back]

     void leftbuffer(Boolean bool)

     void rightbuffer(Boolean bool)

PARAMETERS    [Toc]    [Back]

     bool   is either TRUE or FALSE.

	    TRUE enables updating the left/right buffer.

	    FALSE disables updating the	left/right buffer.

     By	default, leftbuffer is TRUE and	rightbuffer is FALSE.

DESCRIPTION    [Toc]    [Back]

     The normal	framebuffer can	be configured for stereo buffering (see
     stereobuffer).  When this is done in single buffer	mode, two color
     buffers are created, one for the left-eye view and	one for	the right-eye
     view.  When this is done in double	buffer mode, four color	buffers	are
     created: front-left, front-right, back-left, and back-right.  In single
     buffer mode leftbuffer controls whether drawing is	enabled	in the left
     buffer, and rightbuffer controls whether drawing is enabled in the	right
     buffer.  In double	buffer mode, the front-left buffer is enabled for
     drawing if	both frontbuffer and leftbuffer	are true, and the back-left
     buffer is enabled for drawing if backbuffer and leftbuffer	are true.
     Likewise, the front-right buffer is enabled for drawing if	both
     frontbuffer and rightbuffer are true, and the back-right buffer is
     enabled if	both backbuffer	and rightbuffer	are true.

     leftbuffer	and rightbuffer	are ignored when the normal buffer is not
     configured	for stereo buffering.

     leftbuffer	and rightbuffer	should be called only while the	draw mode is
     NORMALDRAW.

     After each	call to	gconfig, leftbuffer is enabled and rightbuffer is
     disabled.

NOTES    [Toc]    [Back]

     IRIS-4D G,	GT, GTX, VGX, and VGXT models, the Personal Iris, Indigo
     Entry, Indy, XL, XS, XS24,	XZ, Elan and Extreme systems do	not support
     leftbuffer	or rightbuffer.

     At	most four color	buffers, such as front-left, front-right, back-left,
     back-right, and zdraw, can	be rendered into simultaneously	on the IRIS-4D
     RealityEngine model.
