I'm a real newb, and could use some help being pointed in the right direction, please.
I am looking to replicate something like the 2D animation below but in 3D space. Where concentric ripple circle "lines" (swept geometry?) emanate from a central point to illustrate soundwaves. Of course, this is something I could replicate in Adobe After Effects, etc., but I'm looking to run some simulations and have these "lines" bounce off walls. The blender video below also illustrates the effect I am after. Any ideas on how to procedurally create such a visual is very welcome. I'd even been got with there being no actual geometry simply having lines in the simulation. Thanks for the help, everyone.
