rightbuffer(3G)

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

C SPECIFICATION
     void leftbuffer(Boolean bool)

     void rightbuffer(Boolean bool)

PARAMETERS
     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
     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
     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.
