OBJ Mesh 3D Model

obj_mesh(
  filename,
  center = FALSE,
  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),
  materialspath = NULL,
  material = NULL
)

Arguments

filename

OBJ filename.

center

Default `FALSE`. Whether to center the mesh.

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.

materialspath

Default `NULL`. Path to the MTL file, if different from the OBJ file.

material

Default `NULL`, read from the MTL file. If not `NULL`, this accepts the output from the `material_list()` function to specify the material.

Value

List describing the mesh.
