The process of combining GUI and 3D canvas in Three-js and React involves the following steps:
- Import the necessary libraries, including React, Three-js, and any other UI libraries like React Bootstrap or Material-UI.
- Create a Three-js scene and camera using the Three-js API. Set up the necessary lighting and other properties.
- Create a Three-js renderer and add it to the DOM using React useRef hook.
- Create a React component for the GUI using UI libraries like React Bootstrap or Material-UI.
- Add event listeners to the GUI elements using React state and props. These events can manipulate the Three-js scene.
- Render the React component and the Three-js renderer inside a parent component using JSX.
- Create Three-js objects like meshes and add them to the scene.
- Animate the Three-js objects using requestAnimationFrame and add the necessary controls using libraries like OrbitControls.
- Run the application.
Overall, the process involves creating a React component for the GUI and a Three-js scene using the Three-js API, then integrating the two using React state and props. The final step involves animating the Three-js objects and adding the necessary controls.
