FaceForm

  • FaceForm[ gf , gb ] is a three-dimensional graphics directive which specifies that the front faces of polygons are to be drawn with the graphics primitive gf, and the back faces with gb.
  • The graphics specifications gf and gb must be CMYKColor, GrayLevel, Hue or RGBColor directives, or SurfaceColor objects.
  • Specifications given outside of FaceForm will apply both to the 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).
  • See the Mathematica book: Section 2.9.9.
  • See also: EdgeForm.

    Further Examples

    We load the package that contains definitions for polyhedra and show two graphics for comparison.

    In[1]:=

    The FaceForm directive will have color the front (outside) of each polygon light gray and the back (inside) face dark gray.

    Evaluate the cell to see the graphic.
