mesh3d_mesh {rayvertex}

Mesh3d 3D Model

Description

Mesh3d 3D Model

Usage

mesh3d_mesh(
  mesh,
  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 = material_list()
)

Arguments

mesh

Mesh3d object.

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.

Examples

if(run_documentation()) {
  # Read in a mesh3d object and rasterize it
  library(Rvcg)
  data(humface)
  
  mesh3d_mesh(humface,position = c(0,-0.3,0),scale = 1/70,
              material=material_list(diffuse="dodgerblue4", type="phong", shininess=20,
              ambient = "dodgerblue4", ambient_intensity=0.3)) |>
    rasterize_scene(lookat = c(0,0.5,1), light_info = directional_light(c(1,0.5,1)))
 }
 
 if(run_documentation()) {
  # Subdivide the mesh for a smoother appearance
  mesh3d_mesh(humface,position = c(0,-0.3,0),scale = 1/70,
              material=material_list(diffuse="dodgerblue4", type="phong", shininess=20,
              ambient = "dodgerblue4", ambient_intensity=0.3)) |>
    subdivide_mesh() |> 
    rasterize_scene(lookat = c(0,0.5,1), light_info = directional_light(c(1,0.5,1)))
