3D Models
3D models are an opportunity to take objects from the real world and share them online. Think about your classroom teaching. Maybe you use a physical prop or demonstrate some equipment?
Representing these as 3D models allows these limited resources to be shared with a wider audience. And students can examine and manipulate them in a similar manner as the real world.
See below for techniques to turn physical objects into 3D models.
Structure Sensor
This is a £400 alternative to expensive 3D scanner. It clips onto an iPad and uses infrared scans to capture the object. It works best on larger objects (50cm +) and requires a well-lit room with lots of space. Avoid sunlight as much as possible as this will interfere with the scans.
The scan below was taken in our built environment resource room.

Zephyr by 3D Flow
This free software allows you to make 3D models using a HD camera. The object must be photographed from different angles. 50 photos give a good result. Placing the object on a base with a distinctive pattern helps the software stitch each photo together.
The software works well on objects of various sizes (10cm + ) providing they are non-shiny and have a lot of texture. The downside is the rendering process can take a long time, over 2 hours!
The scan below was taken at home using no specialised equipment.

Qlone
Qlone is a free app which enables you to make 3D scans using your iPhone or Android mobile.
Objects are placed on top of a printed marker. This helps the software track the model as the camera moves but limits the size of the object to be scanned.
The quality of the models isn’t as good as other methods, but the process is quick and easy. It opens the possibility for students to scan objects themselves and share them with the class.
