Add 3D Model to Website in 8 Minutes – Three.js Tutorial

In this tutorial, we’re going to show you how to put a 3D model on your website with 360 degrees viewer using Three.js and JavaScript in just a few minutes.



Key Points

At the end of this tutorial, the reader will get to learn about:


  • 3D objects, formats, and some of their properties.
  • How to create or acquire 3D objects for their website.
  • Inserting a 3D object in a website.
  • Formatting the 3D object inserted into the webpage.

Prerequisites

Before we begin, some prerequisites for this tutorial include:

  • Basic knowledge with good understanding of HTML and web development.
  • A basic understanding of CSS.
  • A basic web development IDE or a text editor installed on your machine. In our case, we will be using Visual Studio Code.
  • A stable internet connection.

What are 3D objects?

If this question is in your mind, we can easily answer it by saying that 3D objects or 3D models are shapes with three dimensions: length, width, and height.

How to get 3D Objects?

We can obtain 3D Objects by either creating one from scratch, scanning real-life objects, modifying templates to suit your need, and downloading online models. We are going to look briefly at each of the methods mentioned above.


Creating 3D objects from scratch

One may create 3D objects from scratch using 3D model creation software, which is downloadable into the computer. One may also design it online at 3D modeling sites.


Scanning from real-life objects

You can create one by scanning the item with your scanner of choice. Photogrammetry is another process that one may use. Photogrammetry can be simply defined as the art of acquiring reliable measurements from 2D images by overlapping them to form a 3D model. This method is much simpler and more preferable since one can use 2D images generated with a smartphone and obtain live 3D models.
