A comprehensive UI component library designed for building professional 3D editors and interactive tools in the browser. This monorepo contains two complementary packages that work together to provide both low-level UI components and high-level GUI solutions.

Checkout the storybook for more information.

A dedicated React component library for building 3D editor interfaces, featuring:

• Basic Components: Button, Input, Slider, etc.
• Editor-Specific Components: ColorPicker, BezierCurveEditor, GradientSlider, ParticleSlider, AssetPicker
• Accessibility First: All components are designed with accessibility in mind
• Theme Support: Built-in light and dark themes
• TypeScript: Full type safety and IntelliSense support
• Controllable State: Most components support both controlled and uncontrolled modes

import { Button, ColorPicker } from '@galacean/editor-ui'

function App() {
  return (
    <div>
      <Button>Galacean Editor</Button>
      <ColorPicker mode="solid" value={color} onValueChange={setColor} />
    </div>
  )
}

An opinionated GUI library built on top of @galacean/editor-ui, providing:

• Imperative API: dat.gui-like interface for quick prototyping
• Declarative Components: React form components for complex UIs
• Rich Input Types: Vector inputs, color pickers, sliders, and more
• Group Management: Organize controls into collapsible groups
• 3D Engine Integration: Perfect for 3D scene manipulation

// Imperative API (similar to dat.gui)
const gui = new GUI(sceneData, [
  {
    label: 'Camera Position',
    bindPath: 'camera.position',
    type: 'Vector3',
    onChange(value) {
      camera.transform.setPosition(value.x, value.y, value.z)
    },
  },
])

// Declarative React Components
import { FormItemVector3, FormItemColor } from '@galacean/gui'

function ScenePanel() {
  return (
    <div>
      <FormItemVector3 label="Position" value={position} onChange={setPosition} />
      <FormItemColor label="Light Color" value={lightColor} onChange={setLightColor} />
    </div>
  )
}

# For basic UI components
npm install @galacean/editor-ui

# For GUI controls (includes editor-ui)
npm install @galacean/gui

<script src="https://unpkg.com/@galacean/gui/dist/index.umd.js"></script>
<script>
  const gui = new GUI(data, [
    {
      label: 'Camera Position',
      bindPath: 'camera.position',
      type: 'Vector3',
      onChange(value) {
        // Update your 3D scene
      },
    },
  ])
</script>

import { WebGLEngine, Camera } from '@galacean/engine'
import { GUI } from '@galacean/gui'

const engine = await WebGLEngine.create({ canvas: 'canvas' })
const camera = scene.createRootEntity().addComponent(Camera)

const gui = new GUI({ camera: { fov: 45 } }, [
  {
    label: 'Field of View',
    bindPath: 'camera.fov',
    type: 'Slider',
    min: 10,
    max: 120,
    onChange(value) {
      camera.fieldOfView = value
    },
  },
])

import * as THREE from 'three'
import { GUI } from '@galacean/gui'

const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000)

const gui = new GUI({ camera: { position: { x: 0, y: 0, z: 5 } } }, [
  {
    label: 'Camera Position',
    bindPath: 'camera.position',
    type: 'Vector3',
    onChange(value) {
      camera.position.set(value.x, value.y, value.z)
    },
  },
])
