In rayvertex: 3D Software Rasterizer

Sphere 3D Model

Description

Sphere 3D Model

Usage

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,
  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 '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.
