The process of combining GUI and 3D canvas in Three-js and React involves the following steps:

1. Import the necessary libraries, including React, Three-js, and any other UI libraries like React Bootstrap or Material-UI.
2. Create a Three-js scene and camera using the Three-js API. Set up the necessary lighting and other properties.
3. Create a Three-js renderer and add it to the DOM using React useRef hook.
4. Create a React component for the GUI using UI libraries like React Bootstrap or Material-UI.
5. Add event listeners to the GUI elements using React state and props. These events can manipulate the Three-js scene.
6. Render the React component and the Three-js renderer inside a parent component using JSX.
7. Create Three-js objects like meshes and add them to the scene.
8. Animate the Three-js objects using requestAnimationFrame and add the necessary controls using libraries like OrbitControls.
9. 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.
