@adhiban/three-mesh-ui/src/utils/deepDelete.js

a library on top of three.js to help in creating 3D user interfaces, with minor changes ;)

import UpdateManager from '../components/core/UpdateManager.js';

/** Recursively erase THE CHILDREN of the passed object */
function deepDelete( object3D ) {

	object3D.children.forEach( ( child ) => {

		if ( child.children.length > 0 ) deepDelete( child );

		object3D.remove( child );

		UpdateManager.disposeOf( child );

		if ( child.material ) child.material.dispose();

		if ( child.geometry ) child.geometry.dispose();

	} );

	object3D.children = [];

}

export default deepDelete;
