<model-viewer-effects>

<model-viewer-effects> is a web component library addon for <model-viewer> that makes adding post-processing effects to your models easy to do, on as many browsers and devices as possible.

<model-viewer-effects> strives to give you great defaults for rendering quality and performance.

Examples • Documentation

Usage

Using effects is as simple as adding the <effect-composer> inside your <model-viewer>, and placing any effects inside the composer component.

<model-viewer src="...">
  <effect-composer>
    <bloom-effect></bloom-effect>
  </effect-composer>
</model-viewer>

PostProcessing

<model-viewer-effects> uses the postprocessing library under the hood, for its superior performance and support.

In addition to the built-in effects wrapped by this library, you can add any custom effects/passes that follow the postprocessing spec.

XR Support

The effects are not supported in the <model-viewer> XR modes, which will render as usual.

Installing

NPM

The <model-viewer-effects> library can be installed from NPM:

npm install three @google/model-viewer @google/model-viewer-effects

HTML

<model-viewer-effects> and <model-viewer> share a Three.js dependency. In order to avoid version conflicts, you should bring Three through an import-map:

<!-- ES-Shims for older browser compatibility -->
<script async src="https://ga.jspm.io/npm:es-module-shims@1.7.1/dist/es-module-shims.js"></script>

<!-- Import Three.js using an import-map -->
<script type="importmap">
  {
    "imports": {
      "three": "https://cdn.jsdelivr.net/npm/three@^0.157.0/build/three.module.min.js"
    }
  }
</script>

You should then bring the module version of <model-viewer>, along with <model-viewer-effects> from your favourite CDN, such as jsDelivr:

<script type="module" src=" https://cdn.jsdelivr.net/npm/@google/model-viewer/dist/model-viewer-module.min.js "></script>

<script type="module" src=" https://cdn.jsdelivr.net/npm/@google/model-viewer-effects/dist/model-viewer-effects.min.js "></script>

Browser Support

<model-viewer-effects> is supported on the last 2 major versions of all evergreen desktop and mobile browsers, and on all platforms (Android, IOS, MacOS, Windows, Linux).

	Chrome	Firefox	Safari	Edge
