@carolhmj I started to implement raycasting for the GreasedLine. It’s a ThreeJS port so it was easier for me to verify the raycast algorithm by implementing all the underlying ThreeJS methods I couldn’t find in BabylonJS
Thanks!

Hi my friends!
EDIT:
You can find the docs here. The examples released before July 2023 are obsolete.
Creating A GreasedLine | Babylon.js Documentation
I started to work on porting the THREE.MeshLine code to BabylonJS and the first version is already working. With MeshLine you can draw cool lines with a tons customizations available and all this happens on the GPU.
I’d like to ask the community to which way should I move on further? Do we want the MeshLine extend a Mesh? Now there is Mesh…
import { Vector3 } from './Vector3.js';
const _vector = /*@__PURE__*/ new Vector3();
const _segCenter = /*@__PURE__*/ new Vector3();
const _segDir = /*@__PURE__*/ new Vector3();
const _diff = /*@__PURE__*/ new Vector3();
const _edge1 = /*@__PURE__*/ new Vector3();
const _edge2 = /*@__PURE__*/ new Vector3();
const _normal = /*@__PURE__*/ new Vector3();
class Ray {
constructor( origin = new Vector3(), direction = new Vector3( 0, 0, - 1 ) ) {
this.origin = origin;
this.direction = direction;
}

If someone can give me hints how to do all the math using already available BabylonJS methods, it would be damn cool!
