OBJ Mesh 3D Model

Description

OBJ Mesh 3D Model

Usage

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.

Examples

if(run_documentation()) {
#Read in the provided 3D R mesh
generate_cornell_mesh(ceiling=FALSE) |> 
  add_shape(obj_mesh(r_obj(),position=c(555/2,555/2,555/2),scale=400,angle=c(0,180,0))) |> 
  rasterize_scene(light_info = directional_light(direction=c(0.2,0.5,-1)))
}
