Reactive patching with vvvv gamma
You’re familiar with the basics of vvvv gamma but want to understand more? VL offers features that will help you to create more complex and performant programs.
In this webinar, we’re introducing you to the basic concepts of reactive programming. The new Reactive category gives you tools to handle asynchronous events, background calculations and even enables you to build your own mainloop that runs on a different CPU core. But let’s start with a pragmatic explanation of what it is:
Reactive programming is programming with asynchronous data streams
In a way, this isn’t anything new. Event buses or your typical click events are really an asynchronous event stream on which you can observe and do some side effects. Reactive is that idea on steroids. You are able to create data streams of anything, not just from click and hover events. Streams are cheap and ubiquitous, anything can be a stream: variables, user inputs, properties, caches, data structures, etc. For example, imagine your Twitter feed would be a data stream in the same fashion that click events are. You can listen to that stream and react accordingly. On top of that, you are given an amazing toolbox of functions to combine, create and filter any of those streams.
Since a while VVVV and VL use these so called Observables to handle external events (i.e. mouse, keyboard etc.) and asynchronous data. This was mostly under the hood and the actual operations for observables are hidden in the VL.DevLib. The reason is that out of the box the operations do not go well together with the frame based Update concept of VL because they are intended to be called only once or when something has changed. But as of now we have wrapper nodes for the most common observable operations that do exactly that, listen for change and only rebuild the observables when necessary.
