OrbitControls

Description:

OrbitControls is a control module for the three.js library and is commonly used to enable interactive 3D camera movements, such as orbiting around a target point, zooming, and panning. It provides an intuitive way to navigate 3D scenes and is particularly useful for architectural visualizations, 3D modeling, and gaming applications.

Usage:

To use OrbitControls, you typically follow these steps:

Import the OrbitControls component from @react-three/drei.

import { OrbitControls } from '@react-three/drei';

Include the OrbitControls component within your Canvas component to enable camera interactions.

<OrbitControls />

Customize the OrbitControls component by adjusting its properties to suit your specific requirements.

Example:

import React from 'react';
import { Canvas } from 'react-three-fiber';
import { OrbitControls } from '@react-three/drei';
 
function MyScene() {
  return (
    <Canvas>
      <OrbitControls
        autoRotate // Enables auto-rotation of the camera
        enablePan={false} // Disables panning
        dampingFactor={0.05} // Adjusts the damping for smoother motion
        zoomSpeed={0.5} // Adjusts the zoom speed
      />
      {/* Add your 3D objects here */}
    </Canvas>
  );
}
 
export default MyScene;

Properties:

autoRotate: A boolean that enables or disables auto-rotation of the camera. When enabled, the camera will continuously rotate around the target point. Default is false.
enablePan: A boolean that enables or disables panning of the camera. When enabled, the user can drag the scene to pan it. Default is true.
dampingFactor: A numeric value that adjusts the damping factor for smoother camera motion. Higher values result in slower damping. Default is 0.05.
zoomSpeed: A numeric value that adjusts the speed of zooming in and out. Default is 1.

Methods:

OrbitControls does not expose public methods to control the camera programmatically. Instead, it directly interacts with the camera and responds to user input events (e.g., mouse or touch events) to provide camera control.

Notes:

OrbitControls should be used within a Canvas component from react-three-fiber to ensure proper integration with your 3D scene.
To achieve more advanced camera control or implement custom interactions, you may need to access the underlying camera directly and modify its properties or use additional libraries in conjunction with OrbitControls.
