Each lesson begins with a starter folder to download.
Then, simply follow the tutorial!

If you don't like videos, each lesson is also available as text with screenshots, video previews, snippets with syntax coloration, etc.

Plus, you can slow down or speed up the videos!

What will you learn?

The course is complete, yet accessible for beginners. We will start by discovering what WebGL is and why using the Three.js library is a must. We will then discover the various components of Three.js and once the basics are acquired, we will move on to more advanced techniques to display millions of particles, add physics, add interactions, create a galaxy, animate a raging sea, etc.

At the end of the course, you will have a deep understanding of Three.js and enough experience to start your own projects.

As a bonus, we will also learn how to use the 3D software Blender to be able to create our own models.

Is this course for you?

The course is beginner friendly

Geometry illustration
You don't need to have done WebGL or Three.js before.

This training is intended for absolute beginners and will explain the basics before tackling more advanced topics.

Calculator illustration
You don't have to be good at mathematics.

Yes, we're going to do mathematics, but at a simple level and we will explain how it works with drawings and practice slowly.

3D axes illustration
You don't need to know how to use 3D software.

Together we will learn the basics of the 3D software Blender to create a model and import it into our scene.

JavaScript illustration
You don't need to be good at JavaScript.

All you need are JavaScript basics like variables, objects, arrays, loops, functions and events. We will learn the rest together.

Computer illustration
You don't need a crazy ass computer.

In some lessons, we will tackle performance limits, and learn how to handle and optimize our code to get good frame rates.

Frequently Asked Questions

What are the prerequisites?

Even if the course is beginner friendly, you need to know JavaScript basics like variables, objects, arrays, loops, functions, conditions and events.

The code editor used in the lessons is Visual Studio Code but you can use any editor you like.

The browser used in the lessons is Chrome but you can use any browser you like. However, it is recommended to use one with a good developer tools panel like Chrome or Firefox.

Eventually, you will have to install Blender, but the software is free and works on all major OS.

Can I use Three.js with React?

Yes, thanks to the React Three Fiber renderer, we can write Three.js application directly in React.

And it doesn't stop there. React Three is a huge ecosystem with many tools and features that will improve your developer's life.

It's so big that a whole chapter is dedicated to the topic.

And if you don't know React, the course includes a 4 hours long lesson that will teach you the basics of React.

What if I need help?

With the course, you will also get access to a members-only Discord server. If you get stuck or you don't understand a specific part of a lesson, you can share your problem to get help.

I don't speak English very well. Will it be a problem?

The lessons are only available in English without subtitles.

But it's a slow and easily understandable English.

At the bottom left of the video, you can see slides containing the main information of what is being said during the course.

All the lessons are available as text right below the video with the exact same content (screenshots, code snippets, video previews, etc.)

Finally, if it's going too fast, you can slow down the video.

Can I offer it?

Yes, you can gift the course to someone else by clicking on this link.

You can pick an option between letting us email the gift to the receiver or you can share the gift yourself.

You'll receive an invoice by email and the receiver won't have access to your billing information.

Can I test the lessons?

The first lessons are free! Have a look and see for yourself if you like the content.

And if it's not enough, the beginning of every other lesson is also free.

What if I don't like the course?

If you are not happy with the course, whatever the reason is, you can ask for a refund at any time by sending an email at

Following the refund, your account will be deleted.

Is there a way to get a discount?

The price of the course has already been calculated to be as low as possible in order to be accessible for everyone and the VAT is included.

You pay only once and get access to all the lessons, a members-only Discord server and upcoming updates!

Still, if it's too expensive for you, discounts might happen at some occasions. Follow @bruno_simon on Twitter to be alerted.

Do I have to do the entire course to start my own project?

No! Once you feel comfortable, you can start working on your personal experiences by yourself. You won't have to wait until the end of the course, but obviously, you will be able to jump back to the course at any time where you left it.

And if you struggle on any project, whether it is personal or professional, the Three.js Journey community will always be happy to help.

Do you provide a certificate of completion?

Yes! Each lesson comes with a quiz. Completing all quizzes will grant you access to a public certificate that you can print or share with the world.

Failing on answering a quiz will result in a few minutes time out, letting you time to find the information before answering again.
