arrow3d

Draw a 3D Arrow in an RGL Scene

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

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

`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`.

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