1. A computer-implemented method comprising:
receiving a configuration for a point-cloud frame labeling service;
initializing a point-cloud environment in a virtual reality (VR) device according to the configuration;
loading point-cloud data and 3D bounding boxes into a memory buffer of the VR device, wherein the point-cloud data is compatible with a VR environment and a non-VR environment;
drawing the loaded point-cloud data and 3D cuboid annotations by the VR device;
receiving user input in a task user interface of the VR device; and
in response to the input, performing an operation to a bounding box.
