gplot3d.loop
draws a "loop" at a specified location; this is used to designate self-ties in gplot3d
.
gplot3d.loop(a, radius, color = "white", alpha = 1)
a vector or three-column matrix containing origin X,Y,Z coordinates.
the loop radius, in current plotting units. May be a vector, if multiple loops are to be drawn.
the loop color. May be a vector, if multiple loops are being drawn.
alpha (transparency) value(s) for loops. (May be a vector.)
None.
gplot3d.loop
is the companion to gplot3d.arrow
. The "loops" produced by this routine currently look less like loops than like "hats" -- they are noticable as spike-like structures which protrude from vertices. Eventually, something more attractice will be produced by this routine.
