Generate an arrow mesh

Creates a 3D arrow from from to to, with a cylindrical shaft and a conical head.

Usage

generate_arrow(
  from,
  to,
  shaft_radius = 0.1,
  head_radius = 0.3,
  head_length = 0.6,
  segments = 32,
  color = c(1, 1, 1, 1)
)

Arguments

from

Length-3 start point.

to

Length-3 end point (tip of the arrowhead).

shaft_radius

Radius of the shaft cylinder.

head_radius

Radius at the base of the conical head.

head_length

Length of the arrowhead.

segments

Subdivision count (default 32).

color

Length-4 RGBA colour.

Value

A mesh descriptor list.

Examples

mesh <- generate_arrow(c(0, 0, 0), c(0, 2, 0))
nrow(mesh$vertices)
#> [1] 227
