rounded_regular_polygon: Generate regular polygon with rounded corners

In mathiasisaksen/artKIT: Useful functions for creating visual/generative art

Description

This function computes the vertices of a regular polygon with rounded corners.

Usage

rounded_regular_polygon(
  num.edges = 3,
  center = c(0, 0),
  radius = 1,
  rotation = 0,
  corner.radius = 0.25,
  vertices.per.corner = 50
)

Arguments

num.edges	The number of edges that the regular polygon contains.
center	The center/centroid of the shape. Can either be a 1 x 2 data frame/matrix or a numeric vector length 2.
radius	The radius of the circumscribed circle of the regular polygon.
rotation	The amount of rotation applied to the shape, in radians.
corner.radius	The radius of the circular arcs.
vertices.per.corner	The number of vertices that each circular arc consists of.

Value

A data frame containing the columns x and y, where each row is a vertex in the rounded polygon.

Note

The result may contain less than num.edges*vertices.per.corner vertices. In certain situations, consecutive vertices will end up having the same coordinates. The duplicates are then removed.

Examples

# Create a rounded hexagon
vertex.df = rounded_regular_polygon(
  num.edges = 6,
  center = c(5, 6),
  radius = 2,
  rotation = pi/4,
  corner.radius = 0.5
)

# How the rounded hexagon looks:
library(ggplot2)
ggplot()+
  geom_polygon(data = vertex.df, aes(x = x, y = y))+
  coord_fixed()
