three-inspect

!WARNING
three-inspect is a young project, and breaking changes will likely happen before 1.0.0. If you encounter problems please report them!

three-inspect is an inspector for Three.js projects. It is designed to be minimalistic, powerful, and extensible, with little boilerplate required.

npm i --save-dev three-inspect

Currently, it covers:

• Creating a view of the scene graph and editing object properties, such as materials, transforms, etc.
• Viewing / editing textures.
• Scene helpers (Grid / Axes), light helpers, shadow camera helpers.
• Performance monitoring (resources, framerate, memory, capabilities, misc. stats).

three-inspect uses Tweakpane <3 for its input UI .

Getting started

three-inspect is built with first-class support for Threlte, but can be used without a framework or with other Frameworks such as React Three Fiber, for this setup see the section below.

If you are using Threlte, simply create the inspector by importing the <Inspector> component. The <Inspector> component must be placed in a separate child component of your <Canvas>.

<!-- App.svelte -->
<script>
  import { Canvas } from '@threlte/core'
  import Scene from './Scene.svelte'
</script>

<Canvas>
  <Scene />
</Canvas>

<!-- Scene.svelte -->
<script>
  import { Inspector } from 'three-inspect'
</script>

<Inspector />

Once running, the inspector can be toggled with the i key.

Getting started (Vanilla, R3F, TresJS, etc.)

three-inspect can be used in any Three.js-based environment by importing the createInspector function.

import { createInspector } from 'three-inspect/vanilla'

const targetElement = document.querySelector('div')
const inspector = createInspector(targetElement, {
  scene,
  camera,
  renderer,
})

// When you're finished with the inspector...
inspector.dispose()

Extending

three-inspect uses svelte-tweakpane-ui under the hood, and can be extended by adding additional tweakpane tabs or panes.

<!-- Scene.svelte -->
<script>
  import { Inspector } from 'three-inspect'
  import { TabPage, Slider } from 'svelte-tweakpane-ui'

  let foo = 1
  let bar = 0
</script>

<Inspector>
  <TabPage
    slot="inspector"
    title="world"
  >
    <Slider
      bind:value={foo}
      label="Foo"
      min={1}
      max={30}
    />
    <Slider
      bind:value={bar}
      label="Bar"
      min={0}
      max={1}
    />
  </TabPage>
</Inspector>

Note that some features, such as extending the UI, are not possible using this function.
