Make spirograph arrowheads

Description

Make spirograph arrowheads

Usage

arrow_head_hypotrochoid(
  r = 4,
  R = 3,
  d = r,
  windings = r,
  rotate = 0,
  rescale = c(1, 1),
  nudge = c(0, 0),
  transformations = c("unitizer", "rotater", "rescaler", "nudger"),
  n = 361,
  plot = FALSE
)

arrow_head_deltoid(
  d = 2.6,
  rotate = pi,
  rescale = c(1, 0.5),
  nudge = c(0, 0),
  transformations = c("unitizer", "rotater", "rescaler", "nudger"),
  n = 361,
  plot = FALSE
)

Arguments

r	cycling circle radius
R	fixed circle radius
d	pen distance
windings	windings
rotate	rotation angle in radians
rescale	a single value or 2-length vector for scaling in x and y
nudge	a single value or 2-length vector for nudging in x and y
transformations	a vector of transformation functions
n	number of points in polygon
plot	plot arrowhead if TRUE

Value

a matrix

Examples

star5 <- arrow_head_hypotrochoid(plot = TRUE, rotate = pi)
star5_long <- arrow_head_hypotrochoid(
   plot = TRUE,
   r = 4,
   R = 3,
   rotate = pi,
   rescale = c(1, .4)
   )
deltoid_long <- arrow_head_deltoid(plot = TRUE, rescale = c(1,1))
deltoid_long <- arrow_head_deltoid(plot = TRUE)
deltoid_spaced <- arrow_head_deltoid(plot = TRUE,
                                    rescale = c(.6,.3),
                                    nudge = c(.4, 0))
