3D basics for kids

3D is an exciting field to trigger interest of kids at young age to expose them to the range of possibilities in 3D design. It starts with giving a brief idea of the 3D basics and then exposing to various range of free resources available on Internet that helps kids get exposed to 3D tools such as the TinkerCAD tools from AutoDesk. (CAD - Comupter Aided Design)

3D has has two main aspects. Create a 3D model / object and then animate it to do some action. 3D models can be created from scratch in software or even bought ready made from marketplaces on Internet (search 3D model marketplace on Google) or created using a 3D scanner device or even 3D depth cameras in your mobile phones these days. You can create 3D models with a technique called photogrammetry where you take multiple photos of the object you want to scan and then software takes all these photos and create a 3D model. 3D model is not same as 360 degree view or video.

Then the 3D models are animated to create an action. 

3D models can exist in different file formats such as obj, fbx, stl the same way your 2D images can exist in different file formats such as jpg, png, etc. The exported animation can exist in different video file formats such as mp4, avi, mov etc. 
Different file formats serve different purpose. For example 3D models in STL file format are used for 3D printing.  Learn more about different 3D file formats by searching on Google about them.

TinkerCAD offers a range of simple 3D design tools that kids can start learning to work in the 3D ecosystem. The 3D models then can be exported as 3D model files and then used in HOLOFIL-X app to animate and use in HOLOFIL-cardboard.
