How are motion vectors calculated
WebNumber of intermediate time steps within each time increment dt (specified as DeltaTimes), specified as NSteps and a positive scalar integer. The simByMilstein function partitions each time increment dt into NSteps subintervals of length dt/NSteps, and refines the simulation by evaluating the simulated state vector at NSteps − 1 intermediate points. WebDoes anyone know how cycles motion vector values are calculated? I tried looking at the source code but I couldn't find it. I'm trying to export the motion vectors out as data I can use but can't figure out what it's units are. Somewhere else on the internet says it's in pixels but I don't believe that is the case as I'm getting too much variance.
