How to access the any property of imported point-cloud object - three.js

Question

I’m trying to access any property of my imported point-cloud model.
When I console.log the model within the function loader.load it works. The first problem is that I don’t know how to get the same result outside the function. I did it only with the last three lines of code but initializing the object with different name.
I used the code for point-cloud models from three.js docs and everything works fine except when I want to change the size of the points. I guess it is due to the different structure of my model (photo attached).
Here’s the code that I use.
import './style.css'
import * as THREE from 'three'
import { OrbitControls } from 'three/examples/jsm/controls/OrbitControls.js';
import { PCDLoader } from 'three/examples/jsm/loaders/PCDLoader'
import { BufferAttribute, BufferGeometry } from 'three';
let camera, scene, renderer;
init();
render();
function init() {
renderer = new THREE.WebGLRenderer( { antialias: true } );
renderer.setPixelRatio( window.devicePixelRatio );
renderer.setSize( window.innerWidth, window.innerHeight );
document.body.appendChild( renderer.domElement );
scene = new THREE.Scene();
camera = new THREE.PerspectiveCamera( 30, window.innerWidth / window.innerHeight, 0.01, 40 );
camera.position.set( 0, 0, 7 );
scene.add( camera );
const controls = new OrbitControls( camera, renderer.domElement );
controls.addEventListener( 'change', render ); // use if there is no animation loop
controls.minDistance = 0.5;
controls.maxDistance = 10;
//scene.add( new THREE.AxesHelper( 1 ) );
const loader = new PCDLoader();
loader.load( 'pointcloud.pcd', function ( points ) {
points.geometry.center();
points.geometry.rotateY( Math.PI );
points.geometry.rotateX( Math.PI );
points.geometry.rotateZ( Math.PI );
scene.add( points );
console.log(points)
render();
} );
window.addEventListener( 'resize', onWindowResize );
window.addEventListener( 'keypress', keyboard );
}
function onWindowResize() {
camera.aspect = window.innerWidth / window.innerHeight;
camera.updateProjectionMatrix();
renderer.setSize( window.innerWidth, window.innerHeight );
}
function keyboard( ev ) {
const points = scene.getObjectByProperty( 'pointcloud.pcd' );
switch ( ev.key || String.fromCharCode( ev.keyCode || ev.charCode ) ) {
case '+':
points.material.size *= 1.2;
break;
case '-':
points.material.size /= 1.2;
break;
}
render();
}
function render() {
renderer.render( scene, camera );
}
// I used this to acces the object
const points2 = scene.getObjectByProperty( 'points' );
console.log(points2)

Answer 1

change let camera, scene, renderer; to let camera, scene, renderer, points
to make 'points' global.

Answer 2

because the 'points' object only live inside the function, try create a variable outside the loader.load function, then assign the 'points' object to the new variable before render(); now you can access the 'points' from outside this function
