Hi, I have a LineSegments created with BufferGeometry with attributes color and position. I what to get the Vector3 position of each vertices for label.
Am trying not to make this an xy question but i want to get all the lines in the LineSegments and label them.
Hi!
Could you provide more details on what you want to achieve? Explanatory pictures?
And a live code example, of course.
Some thing like this.
but will have to rotate the labels to match the lines.
Interesting. So what have you tried? 
nothing really, but is it possible to get the position of a vertex?
Yes, all positions are stored in a buffer attribute, that is geometry.attributes.position, where geometry is THREE.BufferGeometry().
A very simple example where you can see it:
