I want to save the generated model as an .obj + .mtl file and import it into Blender. May I ask which UV coordinate values to pass in?
if args.vis:
mesh = o3d.geometry.TriangleMesh()
mesh.vertices = o3d.utility.Vector3dVector(points[:, :3])
mesh.vertex_colors = o3d.utility.Vector3dVector(points[:, 3:] / 255.)
mesh.triangles = o3d.utility.Vector3iVector(faces)

    text = cv2.imread('assets/demo.png')

    
    mesh.triangle_uvs = o3d.open3d.utility.Vector2dVector(xyzrgb)  # ？？？？？？---triangle_uvs ？？？
    mesh.triangle_material_ids = o3d.utility.IntVector([0] * len(faces))
    mesh.textures = [o3d.geometry.Image(text)]

    #save .obj & .mtl 
    o3d.io.write_triangle_mesh('/home/demo01.obj', mesh)
