I assume ‘capsule’ means its using a z value as well and im just using GetPlayerPawn.worldLocation() so its a plane capsule (an ellipsoid?) I assume im just setting z to 0 or at least a const value for all vectors.
Seems ffts involve matrixes. Havnt touched that in cpp yet, maybe I have more learning to do. https://github.com/CSWest/FFT-/blob//FFT/FFT.cpp is based on jerrys paper, there is lots out of there to look at for sure.
That video is also using no gravity because using a transparent bp_ocean for buoyancy before was just finicky.
