Rotate Lines

Description

Rotate Lines

Usage

rotate_lines(
  lines,
  angle = c(0, 0, 0),
  pivot_point = c(0, 0, 0),
  order_rotation = c(1, 2, 3)
)

Arguments

lines

The existing line scene.

angle

Default c(0,0,0). The rotation amount for the x/y/z axes, in degrees.

pivot_point

Default c(0,0,0). The pivot point of the rotation.

order_rotation

Default c(1,2,3). The order in which to perform the rotations.#'

Value

Rotated lines.
