An irregular, "blobby" circle

blob is a drawable similar to circle, except that its radius varies smoothly around the circumference according to Perlin/simplex noise generated with ambient.

Usage

blob(
  x = 0,
  y = 0,
  radius = 1,
  range = 0.2,
  n = 100L,
  frequency = 1,
  octaves = 2L,
  seed = 1L,
  ...
)

Arguments

x, y

Centroid coordinates. Default 0.

radius

Mean radius. Must be non-negative. Default 1.

range

Amplitude of the radius distortion. Must be non-negative. Default 0.2.

n

Number of points used to approximate the outline. Default 100L.

frequency

Noise frequency. Must be non-negative. Default 1.

octaves

Number of noise octaves. Must be a positive integer. Default 2L.

seed

Integer seed for the noise field. Default 1L.
