OBJ Mesh 3D Model

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

Arguments

filename: OBJ filename.
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.
center: Default FALSE. Whether to center the mesh.
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.
