display a 3D animated trajectory
I'm making a pool game and I'm trying to display an animated curved trajectory, a dashed line or a stripe, over the table from the white ball forward (it could be curved depending on the spin).
how can I draw such animated dashed line or stripe over the table?
I don't know where to start, Sprite3d ? drawing on table surface but how?
In my understanding this is not a navigation thing neither is drawing on camera view port because other balls/objects might partially occlude the trajectory, so I'm pretty lost.
thank you in advance
