3D Lines not facing camera

Questions & Answers
1

I'm using the wonderful Vectrosity library to draw 3D lines but I have a problem in as much as some of the lines aren't facing the camera.

The camera remains at the world centre (0,0,0) and the lines are created once only at startup and remain in the scene at all times, and they can be drawn anywhere in the world. What I'm seeing is that the line poly normals all seem to face in one direction and not at the camera, which gives the effect of certain lines appearing thinner than others.

Can anyone shed any light on this?

You should call DrawLine3D whenever the line or camera moves, usually in Update or LateUpdate. That way the line will always be drawn correctly. (As a side note, in order to help with just this sort of thing, Vectrosity 1.4 has a DrawLine3DAlways function, so that 3D lines are automatically updated for you when necessary, similar to what the VectorManager does. 1.4 isn't out yet.)
