is a graphics directive that specifies that edges of polygons and other filled graphics objects are to be drawn using the graphics directive or list of directives g.

Details

  • EdgeForm[] draws no edges.
  • EdgeForm works in both 2D and 3D.
  • Color, opacity, thickness, and dashing directives can be used in EdgeForm.
  • JoinForm can be used to specify how edge segments are joined.
  • EdgeForm applies to Polygon, Disk and Rectangle objects.
  • EdgeForm does not affect the rendering of Line objects.
  • In Graphics, the default is to draw no edges.
  • In Graphics3D, the default is to draw edges around every polygon.
  • No lines are ever drawn at edges formed by one polygon intersecting another.
