 ## SimplifyModifierPlugin
 [Example](https://threepipe.org/examples/#simplify-modifier-plugin/) &mdash;
 [Source Code](./src/plugins/extras/SimplifyModifierPlugin.ts) &mdash;
 [API Reference](https://threepipe.org/docs/classes/SimplifyModifierPlugin.html)
 Boilerplate for implementing a plugin for simplifying geometries.
 This is a base class and cannot be used directly.
 A sample to use it:
 ```typescript
 class SimplifyModifierPluginImpl extends SimplifyModifierPlugin {
  protected _simplify(geometry: IGeometry, count: number) {
    return new SimplifyModifier().modify(geometry, count) as IGeometry
  }
 }
 const plugin = viewer.addPluginSync(new SimplifyModifierPluginImpl())
 const root = await viewer.load('file.glb')
 plugin.simplifyAll(root, {factor: 0.75})
 ```
 Check the [example](https://threepipe.org/examples/#simplify-modifier-plugin/) for full implementation.
 ## MeshOptSimplifyModifierPlugin
 [Example](https://threepipe.org/examples/#meshopt-simplify-modifier-plugin/) &mdash;
 [Source Code](./src/plugins/extras/MeshOptSimplifyModifierPlugin.ts) &mdash;
 [API Reference](https://threepipe.org/docs/classes/MeshOptSimplifyModifierPlugin.html)
 Simplify modifier using [meshoptimizer](https://github.com/zeux/meshoptimizer) library. It Loads the library at runtime from a customisable CDN URL. 
 Note: It does not guarantee that the geometry will be simplified to the exact target count.
 ```typescript
 const simplifyModifier = viewer.addPluginSync(new MeshOptSimplifyModifierPlugin())
 const root = await viewer.load('file.glb')
 simplifyModifier.simplifyAll(root, {factor: 0.75})
 ```
