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, ...)
Initial point (tail of arrow)
Ending point (head of arrow)
Length of each barb, in data units
length of barb as fraction of line length (unless barblen is specified)
opening angle of barbs
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
# NOT RUN { arrow3d(c(0,0,0), c(2,2,2), barblen=.2, lwd=3, col="black") arrow3d(c(0,0,0), c(-2,2,2), barblen=.2, lwd=3, col="red") # }
