Draw a 3D Arrow in an RGL Scene

Description

Draws a 3D arrow in an rgl scene with barbs at the arrow head

Usage

arrow3d(
  p0 = c(0, 0, 0),
  p1 = c(1, 1, 1),
  barblen,
  s = 0.05,
  theta = pi/6,
  n = 3,
  ...
)

Arguments

p0	Initial point (tail of arrow)
p1	Ending point (head of arrow)
barblen	Length of each barb, in data units
s	length of barb as fraction of line length (unless barblen is specified)
theta	opening angle of barbs
n	number of barbs
...	args passed to lines3d for line styling, e.g., color, lwd, etc. See material3d.

Value

Returns (invisibly): integer ID of the line added to the scene
