Ray pick don't work in different directions about xeokit-sdk

Direction vector from point A to B is a B - A, meaning:
directionVectorX = B.X - A.X
directionVectorY = B.Y - A.Y
directionVectorZ = B.Z - A.Z

from this you should be able to create directionVector = [directionVectorX, directionVectorY, directionVectorZ]

Hey,

just to make sure: isn't it null, because you switched origin point with direction vector?

It should work if there will be start and end point, but it looks to me, that there is a starting point and direction vector instead.

So, looks like I misunderstood. But if I have 2 points need get direction from one to other. Could you provide some small example?
