Unlock the Power of 3D Models in Your React Project
Are you ready to take your React project to the next level by incorporating 3D models? In this article, we’ll guide you through the process of rendering and configuring 3D assets created in software programs like Blender or Maya using react-three-fiber.
Prerequisites
Before we dive in, make sure you have a fundamental knowledge of React and Three.js’ architecture, including lighting, geometry, and canvas. You’ll also need to have Node.js installed on your machine.
Creating and Preparing a 3D Model for the Web
When it comes to creating a 3D model, you can use software like Blender or Maya. If you’re new to 3D modeling, you can outsource public-domain glTF files from sites like sketchfab.com. Just remember to check for permission to use an asset before including it in your project.
Converting glTF to GLB
glTF is based on JSON, which means some of its data is stored externally. GLB, on the other hand, stores this data internally, making its size considerably smaller than glTF. To convert glTF files to GLB, you can use tools like glTF-pipeline or the official glTF tool extension for VS Code.
Compressing the Model
To avoid degrading your site’s performance, it’s essential to compress your 3D asset before loading it into your scene. You can use a glTF pipeline compression extension called Draco to compress your model.
Setting Up Your React Project
To set up your react-three-fiber project, create a new React project with Create React App and install react-three-fiber with the command npm install react-three-fiber. Then, install the necessary dependencies, including react-colorful, drei, and Valtio.
Loading the Model into the Scene
To load your model into the scene, you’ll need to convert it into a reusable React component using gltfjsx. This utility package breaks down the model and compiles it into a declarative and reusable JSX component.
Configuring the Model
Once you’ve loaded your model into the scene, you can configure it by adding, removing, and altering parts of the model. You can also animate, add events, and perform conditions on your model using React’s useState Hook and Valtio state management.
Adding Events and Animations
To take your model to the next level, you can add events like onPointerDown and onPointerMissed to allow users to select each part of the model and change its color with a color picker. You can also animate the model using the useFrame Hook, which returns a callback 60 times or more per second, depending on the display refresh rate.
The Possibilities are Endless
With react-three-fiber, the possibilities for creating immersive 3D experiences on the web are endless. Whether you’re building a 3D product viewer, a VR/AR experience, or even a game, R3F makes managing the scene seamless.
