Tube

Tube
represents a 3D tube around the line joining a sequence of points.
Tube
represents a tube of radius r.
Tube
represents a collection of tubes.
Tube
represents a tube around the specified 3D curve.
MORE INFORMATION
  • The radius of the tube can be specified either in absolute coordinates, or as Scaled[s].
  • If no explicit radius is specified, Tube uses a small scaled radius.
  • Tube specifies a different tube radius at the position of each of the points .
  • Tube gives a tube consisting of a sequence of straight segments. It is equivalent to Tube[Line[{pt1, ...}], ...].
  • The following curve specifications can be used:
Line[...]piecewise line segments
BezierCurve[...]composite Bezier curve
BSplineCurve[...]B-spline curve
  • By default, the joins between tube segments are rounded.
  • Different forms of joining between tube segments can be specified using JoinForm.
  • By default, the ends of the tube are rounded.
  • Different caps for the tube can be specified using CapForm.
  • CapForm[None] specifies that the end of the tube should be left open.
  • Colors and other material properties of tubes can be specified using color directives as well as Specularity and Glow.
  • Tubes can be specified as transparent using Opacity directives.
  • Individual coordinates and lists of coordinates in tubes can be Dynamic objects.
