Updated In 6 Graphic
is a graphics directive which specifies that faces of polygons and other filled graphics objects are to be drawn using the graphics directive or list of directives g.
FaceForm[g, gback]
specifies that the front faces of three-dimensional polygons should be drawn with directives g, and the backs with directives gback.
  • Color, opacity and surface color directives can be used in FaceForm.
  • In three dimensions, specifications given outside of FaceForm apply to both front and back faces of polygons.
  • The front face of a polygon is defined to be the one for which the corners as you specify them are in counterclockwise order (right-hand rule).
