JoinForm

JoinForm[type]
is a graphics directive which specifies what type of joins should be used to connect segments of lines, tubes, edges, and related primitives.
  • The following types can be used in JoinForm[type]:
"Bevel"truncate the corner
"Miter"extend the corner toward a point
{"Miter",d}extend by at most d times the line width
"Round"cover the corner with a disk
Nonedo not join segments
  • In 2D, the default is JoinForm[{"Miter", 3.25}]. In 3D, the default is JoinForm["Round"].
  • JoinForm[{"Miter", 1/Sin[Theta/2]}] gives sharp corners for any join angle larger than Theta.
