Check If A Line And A Mesh Intersect In Three.js

I have some cilinders in the scene. When user clicks on some specific points, I´m drawing a line (THREE.Line) between the points. I need to check if the line intersects with any o

Solution 1:

From Three.js documentation:

Ray(origin, direction)

origin -- Vector3 The origin of the Ray.

direction -- Vector3 The direction of the Ray.

So if you have pointA and pointB that are the clicks of the user, you can:

(pseudo code)

origin = pointA
direction = (pointB-pointA).normalize()
myRay = THREE.Ray(origin, direction)

You can do the same with a THREE.Raycaster()
