Questions
1

I need to get the lineTube radius after it initialization, how can I retrieve that ?

2

you could store it in its metadata ?

I hope the chatBot has a good tip for you.

GPT3: To retrieve the radius of a BABYLON.LineTube after it has been initialized in Babylon.js, you can access its path3D property which is an array of BABYLON.Vector3 points, and then calculate the distance between adjacent points to determine the radius.

Here’s an example code snippet:

javascriptCopy code

// create a LineTube
var tube = BABYLON.MeshBuilder.CreateTube("tube", {
  path: path,
  radius: 0.1, // set initial radius
  sideOrientation: BABYLON.Mesh.DOUBLESIDE
}, scene);

// get the path points
var points = tube.path3D.getPoints();

// calculate the radius by finding the distance between adjacent points
var radius = points[0].subtract(points[1]).length() / 2;

console.log("Radius:", radius);

This would not work again :slight_smile: you can not access the path 3d easily and the path is basically the center of the tube so the difference between 2 points won t be the diameter :slight_smile:

Saving the radius or some of the creation options in the metadata / an augmented property or a dedicated storage in the app might be the most convenient way so far.

We are keeping it internally in _creationDataStorage Babylon.js Playground
