In this tutorial, we will explore how to create a stunning animation using React Three Fiber. The concept involves displaying a 3D scene in the background that resembles a distorted glassy view of a text ring rotating around its axis. This design element can serve as an animated background and is perfect for beginners interested in 3D animation.
To begin, ensure you have a React app set up and install React Three Fiber by running the following command:
“`html
npm install three @react-three/fiber
“`
Next, prepare the canvas for rendering the 3D scene. Import the Canvas component from @react-three/fiber, style the main element to occupy 100% of the viewport width and height, and set a black background color. Here’s an example:
“`html
import { Canvas } from “@react-three/fiber”;
export default function App() {
return (
);
}
“`
Then, create a 3D component called “Ring” that will be rendered inside the Canvas. This component wraps the text around a cylinder to form the “TextRing”. Here’s an example implementation:
“`html
interface Props {
radius: number;
height: number;
segments: number;
}
export default function Ring({ radius, height, segments }: Props) {
return (
);
}
“`
Include the “Ring” component in the main scene within the Canvas:
“`html
import { Canvas } from “@react-three/fiber”;
import Ring from “./ring”;
export default function Scene() {
return (
);
}
“`
To add text to the scene and wrap it around the cylinder, install @react-three/drei package and utilize the Text component. Adjust the “Ring” component to position and display the text around the cylinder:
“`html
import { Text } from “@react-three/drei”;
interface Props {
text: string;
radius: number;
height: number;
segments: number;
}
export default function Ring({ text, radius, height, segments }: Props) {
// Calculate positions for text
// Display text around the cylinder
}
“`
Animate the scene by rotating the group along its axes using the useFrame hook from @react-three/fiber:
“`html
import { useRef } from “react”;
import { useFrame } from “@react-three/fiber”;
import { Text } from “@react-three/drei”;
interface Props {
text: string;
radius: number;
height: number;
segments: number;
}
export default function Ring({ text, radius, height, segments }: Props) {
const ref = useRef
// Rotate the text
// Calculate positions for text
}
“`
Finally, apply a glass-like effect to the element using the MeshTransmissionMaterial from @react-three/drei:
“`html
import { MeshTransmissionMaterial, Text } from “@react-three/drei”;
interface Props {
text: string;
radius: number;
height: number;
segments: number;
}
export default function Ring({ text, radius, height, segments }: Props) {
const ref = useRef
// Rotate the text
// Calculate positions for text
}
“`
By following these steps, you can create a mesmerizing rotating glassy text ring in your React Three Fiber project. Enjoy experimenting with different designs and animations! Feel free to reach out for collaborations or projects.
