I wish I knew this before using React Three Fiber

Sometimes the best way to understand a library like React Three Fiber is to compare it to the original 3D web library, Three.js. We’re going to walk through a side-by-side, one-to-one build of a Three.js project and a React Three Fiber project at the same time. After watching this video you will understand:
- Scene creation (cameras, renderers, meshes, animation)
- R3F JSX syntax and special props
- Componentization
- Rendering tricks
The goal is for you to learn exactly how everything works under the hood so that you can be confident building your next React Three Fiber project.

This is a lovely introduction! I love that you compared the two libaries side by side. Your explanations are concise and effective. Thank you!

[@Cloud9er]

Incredibly helpful, can't wait to learn more from these under-the-hood videos you make.

[@shiftstage7892]

Hey, this is absolutely fantastic. As someone who has avoided video explanations and would rather dive and hack in the source code for the longest time, this type of quality content is what developers should strive for. Not the forgettable and template-y one-size-fits-all setup, but a deep dive into the limits of the code, render cycle, performance, and the mindset of the authors of both libraries and what they were attempting to accomplish. I wouldn't mind it to be longer. This channel might be the Jon Gjengset of frontend if you keep it up!

[@Tyler-zb6ec]

Great documentation! Seeing the vanilla and react js side by side helps a ton

[@alamin-yu9mm]

I am glad that there are people like you, who can help beginner streamers. Thank you brother, I appreciate your support. Always fresh updates

[@user-bv4xr3yd8w]

This is an absolutely awesome overview. Your explanations are crystal clear, despite me not having used Three in about a year.

[@mobeen360]

This channel gonna blow up. Thanks, man. Keep up the quality content.

[@ooogabooga5111]

I'm half way into this video, Im just going to say "this is channel is my hidden gem". You have 10/10 explanation style. So easy to understand.

[@ferrazf9]

Thank you so much for this video. A solid explanation on all of these concepts is an absolute godsent.

[@aj35lightning]

incredible, been pretty deep on vanilla three for a long time, been looking at cool stuff done with r3f and i love how quickly it looks like you can develop without a lot of boilerplate, but needed someone to bridge me between the two in exactly this way. this helps so so so much, thanks again

[@RabbitHoleSyndrome]

I'm happy this helped you out! 🙂

[@dalyryl]

this is such a great find on youtube, sir Bruno Simon's videos are gems also but most of the people are into functional components now so this is a good balancer, though the approach of sir Bruno is very great specially with the simpleton which is sir Andrew Woan also uses. Such great channels for ThreeJS enthusiasts. Keep making more of this please

[@BrightSideDeveloper]

Incredible Video! Your amazing for creating this!

[@jx4172]

Great video! Showing different ways to achieve the same things in react-three-fiber was very helpful for my understanding! And thanks for digging into the renderer code and figuring out what was happening! The explanation was really helpful! ps. Nice to see someone not using the * as THREE default import for once. Your code looks so much nicer! pps. subscribed!

Thanks for the video, it's really great and opened up my mind. I started with React Three Fiber but needed to have more control over the general parameters of my scene, like toneMapping and colorSpace, so I took some "vanilla" ThreeJS courses. Now I'm moving back to React Three Fiber. Thanks to you, now I am clear about the "attach" property and the whole logic behind React Three Fiber. You're awesome man. Your explanations are pretty clear and straightforward. 👍
