  • EdgeForm[ g ] is a three-dimensional graphics directive which specifies that edges of polygons are to be drawn using the graphics directive or list of graphics directives g.
  • EdgeForm[ ] draws no edges of polygons.
  • The directives RGBColor, CMYKColor, GrayLevel, Hue and Thickness can be used in EdgeForm.
  • EdgeForm does not affect the rendering of Line objects.
  • No lines are ever drawn when an edge is formed by one polygon intersecting another.
  • See the Mathematica book: Section 2.9.9.
  • See also: FaceForm, Line.

    This displays two polygons, one with the default EdgeForm and one with red edges.
