Sphere 3D Model

sphere_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 = 1,
  low_poly = FALSE,

)

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 `1`. Radius of the sphere.

low_poly

Default `FALSE`. If `TRUE`, will use a low-poly sphere.

material

Default `material_list()` (default values). Specify the material of the object.

Value

List describing the mesh.
