Hello, I am able to raycast to lineSegment2. How to identify which segment is raycasted as segment has numerous points.

You have to use LineSegmentsGeometry rather than LineGeometry otherwise it will create lines connecting every point. [image] Edit fiddle - JSFiddle - Code Playground

You should be able to use faceIndex to get that: mrdoob/three.js/blob/f4b504f004867f1ab7fa1645a10fd991d6db158e/examples/jsm/lines/LineSegments2.js#L193 ray.distanceSqToSegment( line.start, line.end, point, pointOnLine ); intersects.push( { point: point, pointOnLine: poin…

Thanks. I was able to utilize faceIndex for my usecase. However in my use case e.g. positions = [node0,node1,node0,node2,node0,node3]; faceIndex values are coming out as a multiple of 2. Is that expected behaivour?

Looking at the code that doesn’t sound right – can you make a jsfiddle to show what’s happening?
