lagged()

TimeMap MayaFlux::Kinesis::TimeMaps::lagged ( double  origin, double  rate, TimeMap  lag  )

inline

Position of a moving reference minus a lag that can itself change.

Parameters

origin	Reference position at time zero, for a recording its write head
rate	Reference velocity in position units per second, the write rate
lag	Distance behind the reference at each time, in position units

Reading a ring that is still being written gives a tap that trails the write head. Keep the lag above a couple of blocks so the tap stays behind the frames being written.

    return { .fn = [origin, rate, lag = std::move(lag)](const double& t) -> double {
        return origin + rate * t - lag(t);
    } };
