## Overview

UGScan is a Lidar-based 3D scanning app that supports three scanning modes: point cloud, model, and floor plan. It can quickly help you collect 3D data, and allows you to process scans, view results, measure distances, and use AR view directly on your phone. It can also export common 3D formats for sharing with friends.
