Birds - v3.0 Update

@Living_Systems
This looks fun, once in a while the videos pop up and I love this type of nature simulation.
I just keep wondering why collision tracers are used for individual birds. Wouldn’t it be more performant to cache data in forms like a heat map / flow map to pull preferred movement and avoidance data from by location? Probably you already set up some form of optimization the videos just get me curious about that in particular. It could get rid of tracers entirely until the moment you need a dynamic avoidance response. Or, the heatmap is updated every X seconds to provide new data, similar to the dynamic pathing built into the engine. Traces don’t have to be heavy at all but with 100 birds in a level :slightly_smiling_face:
