glCullFace
specifies whether front- or back-facing polygons are culled (as specified by mode
) when culling is enabled. To enable and disable culling, call glEnable
and glDisable
with argument GL_CULL_FACE
. Culling is initially disabled.
glFrontFace
specifies which of the clockwise and counterclockwise polygons are front-facing and back-facing.
If mode
