Boomerang / Frisbee trajectory visualization and control

Hi,
I need to develop a Boomerang / Frisbee trajectory visualization and control it with touch for 3D mobile game just like this one:

But I have no idea how to get started, any suggestions on how to achieve this effect.
Thank you.

 

Your good starting point, may be a Bezier spline. If you search forum, there is even open source project available.
In fact, here is a link.

This is definitely a spline. It is not necessarily a Bezier spline, and could be a Camull Rom one, but bezier would give you a better trajectory control.

 

I would say this are multiple splines connected with flipped control points at connection (for smooth joining).

 

That's what Bezier spline does.

I would start with DOTween.
