9.1.6 Back face culling
In CORAL, a triangle direction can be defined and a mode in which drawing for the back face is
inhibited (back face culling) is supported. The on/off operation is controlled by the GMDR2[0] setting.
GMDR2[0] must be set to 1 only when back face carling is required. When back face culling is not
required such as in ‘line,’ ‘point,’ and ‘polygon primitive,’ GMDR2[0] must be set to 0.
