angular_velocity() [1/2]

float MayaFlux::Kinesis::angular_velocity ( const Memory::HistoryBuffer< float > &  headings, double  dt  )

inlinenoexcept

Angular velocity from consecutive headings in a HistoryBuffer.

Parameters

headings	Buffer of heading angles in radians, capacity >= 2
dt	Elapsed time between samples 0 and 1

Returns

Signed rate of heading change in radians per second, wrapped correctly across the -pi/pi seam

Takes a HistoryBuffer<float> of already-computed headings rather than positions directly, since heading is itself derived (see heading() above) and keeping this function ignorant of that derivation keeps it reusable for any angle-producing source, not only motion.
