====== Welcome to PointCloud2BIM_UI ======

The [[start|PointCloud2BIM library]] provides a set of algorithms to facilitate the processing of 3D Laser scans of buildings (Point Clouds) and identification of fundamental entities, such as floors, rooms, walls and openings. 

The PointCloud2BIM_UI is a user interface built on top of PointCloud2BIM library. It provides access to the top level algorithms (floor, room, wall and opening detection) of the PointCloud2BIM library from graphical user interface.

===== About =====

The 3D laser scanning is a convenient and accessible technology to document the existing infrastructure including buildings. The output is a set of data points in space, so-called point clouds. While point clouds can be directly rendered and inspected, they need to be converted into BIM representation for efficient digital processing. The PointCloud2BIM aims to automate this transformation to a large extend by providing a set of tools and algorithms for this purpose.

The PointCloud2BIM_UI is written in JavaScript. It can be compiled into its respective binaries on Unix/Linux systems and Windows systems using Electron.js framework. Each of the segmentation steps is operated in a separate tab. The inputs are specified in user-friendly forms without touching the command line and the PointCloud2BIM library routines run seamlessly in the background.
