Text Object

Description

Text Object

Usage

text3d_mesh(
  label,
  position = c(0, 0, 0),
  text_height = 1,
  orientation = "xy",
  color = "black",
  angle = c(0, 0, 0),
  pivot_point = c(0, 0, 0),
  order_rotation = c(1, 2, 3),
  scale = c(1, 1, 1)
)

Arguments

label

Text string.

position

Default c(0,0,0). Position of the mesh.

text_height

Default 1. Height of the text.

orientation

Default xy. Orientation of the plane. Other options are yz and xz.

color

Default black. Text color.

angle

Default c(0,0,0). Angle to rotate the mesh.

pivot_point

Default c(0,0,0). Point around which to rotate the mesh.

order_rotation

Default c(1,2,3). Order to rotate the axes.

scale

Default c(1,1,1). Scale of the mesh. Can also be a single numeric value scaling all axes uniformly.

Value

List describing the mesh.
