Timing utilities for handling recurring events, fading, framerate counting.

ofxTiming is an addon for openFrameworks

ofxTiming provides classes that implement common patterns associated with timing.

DelayTimer

An asynchronous buffered intervalometer that will accept a framerate, and return a true tick() when it's time to execute an event associated with that interval.

FadeTimer

A class that returns a state between 0 and 1 that will fade from one end to the other given start() or stop(), correctly handling intermediate cases.

Hysteresis

A class for filtering and tracking noisy input. This also plugs into FadeTimer.

RateTimer

A class for timing framerates or intervals of time.

ofxtiming's Issues

I get linker errors with multiple definitions of humanDuration in gcc in archlinux armv7l

They go away when I declare the function inline.

raspberry pi 4 warnings and error

I am using OF 0.11 on RPI 4 and get these errors which I do not get on macOS.

Will start poking around and see if I can figure this out.

example

this looks super useful.
i only got fade and delay working. maybe you have a moment to make some short examples for lerp and hysteresis. :)
thanks.
