Torus 3D Model

torus_mesh(
  position = c(0, 0, 0),
  scale = c(1, 1, 1),
  angle = c(0, 0, 0),
  pivot_point = c(0, 0, 0),
  order_rotation = c(1, 2, 3),
  radius = 0.5,
  ring_radius = 0.2,
  sides = 36,
  rings = 36,
  material = material_list()
)

Arguments

position: Default c(0,0,0). Position of the mesh.
scale: Default c(1,1,1). Scale of the mesh. Can also be a single numeric value scaling all axes uniformly.
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.
radius: Default 0.5. The radius of the torus.
ring_radius: Default 0.2. The radius of the ring.
sides: Default 36. The number of faces around the ring when triangulating the torus.
rings: Default 36. The number of faces around the torus.
material: Default material_list() (default values). Specify the material of the object.

Value

List describing the mesh.
