Rendering 3D lines/paths/arcs


I want to render lines and parabolic arcs in 3D space to visualise navigation and projectile paths like Xcom. Pawn movement will always be a straight line on the XY plane from location A to B. Projectile arcs will be simple parabolic arcs from A to B, again both on the XY plane as discussed here:

I’ve tried messing around with a beam emitter and have some really terrible looking straight paths working with a source/target but trying to do arcs using the source/target tangents ended in tears. Is there a simpler way to draw 3D lines and arcs?


you could just make a 3D model of an arch and then resize it.
