i-Space: 3D Scanner

Consisting of the Digital Makerspace, Digital Visualisation Room and Studios

3D Scanning

3D scanning refers to the process of analyzing real-world objects or environment to collect data on its shape and appearance. The data is then used to construct 3D models and textures of the objects or environment. Digitizing real-world objects in 3D is becoming increasingly common. The 3D models can be processed for 3D printing, importing into video games or VR applications. Below are some tools at i-Space for you to get started with 3D scanning. Come and try them out!

3D Scanning Facilities & Software

3D Scanning Facilities

Many consumer 3D scanners make use of short-range laser scanning technology and are suitable for scanning relatively small objects. A laser line or pattern is projected onto an object and the reflected laser light is captured by a sensor. Distance from the scanner to each scanned surface is calculated. And from these data, a 3D model of the object is constructed.

Two types of laser 3D scanner are available at i-Space. Learn how to operate them from our colleagues and try to scan something in 3D on your own!

Structure Sensor (Handheld 3D Scanner) Matter and Form (Desktop 3D Scanner)


Photogrammetry Software

Photogrammetry software allows 3D coordinates of an object to be derived from photographs of the object taken from different positions and angles. Compared with consumer 3D scanners, very large objects including buildings and landscape can be scanned with this technology. It is thus widely used in GIS applications, cultural heritage documentation and visual effects production.
