torus_mesh {rayvertex}

Torus 3D Model

Description

Torus 3D Model

Usage

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.
