another addition to the series of things that took too long. But then they also say that it is never too late... VL was shipping with OSC and TUIO nodes from the beginning, but frankly, they were a bit cumbersome to use. So here is a new take on working with those two ubiquitous protocols:
To receive OSC messages you need to place an OSCServer node which you configure to the IP and Port you want to listen on. Immediately it will show you if it is receiving OSC messages at all on the Data Preview output.
Then use OSCReceiver nodes to listen to specific addresses. Either specify the address manually or, hit the "Learn" input to make the node listen to the address of the first OSC message it now receives.
Note, that the OSCReceiver is generic, meaning it'll connect to whatever datatype you want to receive. Supported typetags are:
In case of multiple floats, you can also directly receive them as vectors. And this works on spreads of the above types and even on tuples, in case you're receiving a message consisting of multiple different types.
To send OSC messages you first need an OSCClient which you configure with a ServerIP and Port. Then you're using SendMessage nodes to specify the OSC address and arguments to send. Again note that the "Arguments" input is generic, so you can send any of the above types, spreads of those and even tuples combining different types!
By default, vvvv is collecting all the data you send and sends it out in bundles per frame. For optimal usage of UDP datagram size (depending on your network) you can even specify the maximum bundle size on the OSCClient node.
These are the basics. There are a couple of more things which are demonstrated in the howto patches!
For receiving TUIO data you're using a TUIOClient which you configure to the IP and Port you want to listen on. The client already returns a spread of cursors, objects and blobs that you can readily access.
For sending TUIO data you're using a TUIOTracker node which you configure with a ServerIP and Port. Then you give it a spread of cursors, objects and blobs to send out.
Available for testing now, in latest 2020.3 previews!

Previously on vvvv: vvvvhat happened in October 2020
A seemingly calm month, but it is boiling under the covvvvers: First, you notice that we continue to update the 2020.2 release with bugfixes. The latest release is vvvv gamma 2020.2.4.
Then, as mentioned previously, we're currently mostly focused on getting a stable 2020.3 out which will include VL.Stride, our shiny new 3d engine. Best of it: you can follow our daily progress by downloading the preview releases. Already comes with tons of help and demo patches. Give it a spin!
And finally done are the completely reworked, easy to use OSC and TUIO nodes which will show up in one of the coming previews soon!
Two new ones:
A little teaser:
And some new works in progress:
That was it for November. Anything to add? Please do so in the comments!
When Tue, Nov 24th 2020 - 20:00 until Tue, Nov 24th 2020 - 21:30
Save the date!
We're meeting up on November 24th, 8pm CET to get insights into what everyone is patching on. How will this work? Something like the last time. So please invite all your vvvvriends and vvvvamily to join us!
We could have one or two more demos/presentations! Anything more or less related to vvvv, yourself and your projects. Share some thoughts, share your funny fails. Or just ask some questions...
Please get in touch via firstname.lastname@example.org and let us know what you want to talk about. We'll then get back to you and organize the streaming tool etc.
Here is our line-up so far:
wirmachenbunt is a studio for interactive and immersive shows and exhibits. The team will present the Magenta Moon Garden software, the system behind a 360° interactive space, incorporating 16 projectors, 9 Radartouch sensors, 6 channel surround sound, 4 games and lots of pixels. While the visual output is rendered with vvvv beta, they used VL and vvvv gamma heavily for the backend and surround sound engine, marking a transition of the studio workflow. While going into the patch details, they reveal the process, from simulation to the live setup.
Christian is a media artist based in Schwerin. Working on all kinds of kinetic, light and screen based installations, he will give a small peak into his recent project, which will be his first one realized in vl. Switching from Unity and his own custom framework creative computing he will give a view on the process leading into this decision and present some first steps into the vvvv world as a result of the transition.
New media artist with a background in fine arts and philosophy, Amir realizes his works by designing narratives through real-time processes.
Amir is based in Linz/AT where he is persuing his PhD. He is a researcher at Creative Robotics Department at the university for arts and design in Linz he is also teaching Coding and computational thinking at the Fashion and Technology department in the mentioned university.
Previously on vvvv: vvvvhat happened in August 2020
So once again, where were we...
If you haven't noticed yet, the latest previews for vvvv gamma now include VL.Stride, the fancy new 3d engine. We're quite happy with the feedback so far. Things mostly seem to work as expected. We're now focusing on making this preview into the first 2020.3 stable release including VL.Stride. But 3d is not all, we've also included a few other goodies in the 2020.3 branch, which are summarized in a separate blog post with the juicy title: vvvv - The Tool.
Quite a few new works in progress:
That was it for September and October. Anything to add? Please do so in the comments!
the biggest NODE so far, in terms of reach. At least if you want to believe the viewing numbers on the videos of the daily streams. This time the whole world was able to participate and not only a handful of privileged being able to come to Frankfurt. What an undertaking to run a pop-up TV station for 7 days next to a 2 track, 9h a day workshop program...
On behalf of the whole team that made this edition possible, vvvv wants to thank david and Jeanne Charlotte Vogt, directors of NODE20 - Second Nature, for pulling the strings. Once again very well done, chapeau!
The team was huge and a lot of different things happened over the course of this week, too numerous to recap here. So in this blogpost I want to particularly summarize the vvvv focused parts and highlight the members of the vvvv community who helped make NODE20 possible.
You should watch them all: 7 days of quality panels and discussions around this years topic "Second Nature". But then, as promised, the following is a listing of the more vvvv related shows for your viewing pleasure:
And of course to every single one of the 26 workshop hosts and co-host who took the time to bring their knowledge to all of us: andresc4, Anna Meik, antokhio, baxtan, domj, dottore, elias, everyoneishappy, gregsn, Gene Kogan, hayden, idwyr, joreg, jule, kleinkariert, lasal, Maria Heine, Marian Dziubiak, motzi, ravazquez, sebl, sunep, Takuma, tonfilm, untone, vux.
NODE is a community effort. Everyone is chipping in what they can. So finally I want to list a few companies without whose continued support in the form of material or human resources, NODE20 would not have been possible:
vvvv takes a deep bow in front of everyone mentioned. I sincerely hope I didn't forget anyones contribution but am well aware that this is not unlikely. So in case I missed someone, please someone let me know so I can add the info here!
After NODE is before the next NODE.
Back to work!
Me and the complete team recover slowly. NODE was a blast and we can be incredibly proud to made it happen under the 2020 conditions. I do believe that the hybrid approach is something that has some future potential. Heads are spinning already how a next node would need to be.
To get some structured feedback we have setup this survey for all participants:
You can help to make NODE better by filling this out. Thank you so much!
Many have asked us for the workshop recordings. And here are some good news:
Here is the story behind the decision: When we announced the festival in July/August it was clear that we have to give the ticket owners some exclusive access to the recordings afterwards to actually make them onboard the festival. Otherwise - we assumed - many could have chosen to simply wait until the festival is over and wait for the public recording. The festival would not have worked at all.
Now after the festival it feels a bit unnatural to hide the recordings to curious new people. Why not ride the wave of attention we created? Selling the recordings became an option. It would also help to close a financial gap of the overall festival budget. After some talks with the hosts about how we can handle this in a fair way we came to the conclusion that we will split the income between the Instructors and the festival. This feels natural as the institutes idea is to help the community to sustain and help instructors to get revenue for their educational work. The income does not got to the vvvv group but to all community instructors.
Love goes to all of the instructors and organizers and contributors. We are all deeply thankful for their effort and contribution. ravel, sebescudie, Rayment, katzenfresser and Ben Schiek, andresc4, Anna Meik, antokhio, baxtan, domj, dottore, elias, everyoneishappy, gregsn, Gene Kogan, hayden, idwyr, joreg, jule, kleinkariert, lasal, Maria Heine, Marian Dziubiak, motzi, ravazquez, sebl, sunep, Takuma, tonfilm, untone, vux, readme, bjoern,kopffarben and more vvvv people in the program.

A ticket is only 50€ and gives you full access to the festival and workshops plus recordings to rewatch them.
Hope to see you all in cyberspace!
The "getting started" for people who are not necessarily familiar with vvvv beta or other creative coding environments. Here we take you by the hand and start from scratch so from here on you can follow other workshops.
In this workshop, we will be practicing the commonly known aspects of generative design algorithms. Despite the wide range of the term, we will introduce you to the fundamentals as well as simple tips and tricks.
While designing a learning app for kids, you will learn object-oriented patching patterns along the way. We will go from 0 to exe in 3 hours.
Get a short introduction to vvvv and learn how to use chains of visual effects to get from zero to wow within minutes – Real-time graphics for beginners.
In this introductory workshop, we’ll explore the functionalities and widgets you can find in the VL.Elementa library to effortlessly build wonderful graphical user interfaces.
In this workshop, we’ll show you how easy it is to use any .NET nuget with vvvv and how to navigate common issues that you may encounter doing so.
In this workshop, we will be learning how to constantly produce procedural graphics using the FieldTrip pack.
This workshop will cover the basics of VJing using vvvv. You'll be provided with an initial VJing setup with generative examples, postFX and a composition system, which you can then customize.
vvvv has just adopted the powerful realtime 3D graphics engine Stride 3D. In this workshop, we are looking at its basic concepts and learn to set up a scene with geometries, lights and material.
Creative Coding is about finding inspiration in the process of work. Add a few friends to this process and it is going to be even more inspiring! This workshop gathers participants from all over the world to work together on one patch.
FieldTrip is a vvvv beta pack for working with 2D and 3D scalar and vector fields. Think generative patterns, agents, procedural noise and 3D graphics beyond the triangle.
In this workshop, we'll zoom out and try to gather a birds-eye view onto systems built with VL. We'll explore some of the underlying ideas that helped shaping the patches of some VL libraries or projects.
Maintaining installations with a lot of vvvv clients. Deploying, updating, synchronizing, monitoring, infrastructures based on vvvv and third party tools using vvvv and third party tools.
Everyone can make numbers look interesting – but let’s learn how to make them sound vvvvonderful!
This workshop is for artists, musicians, creative coders, professionals, students, designers, and whoever is interested in creating audio-visual content using vvvv.
This workshop is for everybody who needs a kickstart on the topic of networking in general, how the different protocols (UDP, TCP, MQTT, OSC, ZMQ,..) can be used in vvvv and what properties they have, so you can decide which one fits best for your use case.
In this workshop, we'll guide you through the whole process of turning a .NET class library into an easy-to-use node library for VL.
Schéma is a visual programming environment created in... a visual programming environment, namely vvvv gamma. Curious about building something of this scale in VL, then join this lecture!
In this workshop, we introduce the basic concepts of reactive programming that will make you understand how to work with Observables, react to events, and run computations in a background thread.
In this workshop, we will start with a general overview of the functionality provided by VL.OpenCV to then dive in a hands-on session where we will experiment with some of the more accessible and exciting features that this library ships with.
Materials define the appearance of 3D model surfaces and how they react to light. They can affect both the geometry of a model and its colors and multiple material layers can be combined to build more complex materials. In this workshop, we're going to explore the node-set that allows us to patch custom materials.
In this workshop, we'll get familiar with RunwayML, a tool dedicated to artists willing to use machine learning models in their workflow. Using the vvvv implementation, VL.RunwayML, we'll see how easy it is to integrate an existing model in our patches.
Stride is an open-source C# game engine for realistic rendering and VR. But how to get started? In this workshop we'll go through the basics of getting Stride, managing projects, importing assets and creating and controlling entities in a scene.
Visualprogramming is often equivalent to dataflow programming. With VL though, you can also use metaphors known from object-oriented programming. This means that with VL you can define your own datatypes, instantiate them, manage them in collections and call individual operations on instances.
Visual shader patching? Yes, please! These days, all major game engines have node-based material and/or visual effects editors. And their common purpose is to provide a way to work creatively with CPU and GPU data. The experimental ShaderFX in VL.Stride generalizes this approach and takes it one step further. You work with CPU & GPU data and operations on the same canvas, at runtime – vvvv style.
In this workshop, we will be diving into the VL runtime API. We'll touch general library design philosophies, like offering descriptive high-level process nodes that are easy to play with and talk about enhancing the patching experience for users of our library.
This workshop is for anyone without any experience in electronics/hardware, it's intended as a first contact between code <-> electronics, but with one of the most used and powerful and inexpensive micro controllers.
This talk looks back over a few years of swimming against the tide of Python to make machine learning a technology easy to use with vvvv. You'll see that, by getting your head around a few important principles, running models in vvvv can be pretty straight forward.
One major strength of VL.Stride is that it offers an easy to use scene graph and at the same time lets you go as far down to the graphics API as you want. This workshop will approach 3d rendering from these two opposite ends and you'll learn how to combine them.
