Previously on vvvv: vvvvhat happened in January 2021
What did you do in February?
Well, we did two releases:
- vvvv gamma 2021.3 including the shiny new 3D engine VL.Stride
- vvvv beta 41 including VL 2020.2.6
We're already working on a beta 42 which will include the latest VL 2021.3 and also the next bigger gamma 2021.4 which we'll talk about in a separate blogpost.
We all met for the 8th online meetup and some of you also couldn't resist and once again made some great contributions:
Contributions
- The long-awaited "not your ordinary timeline" Kairos by dottore is out:
- Get the VL.Kairos NuGet
- Watch a brief introduction from the last meetup
- Join the VL.Kairos chat room
- Contribute to VL.Kairos on GitHub
- Note that in order to sustain the project, dottore is asking commercial users to buy a license!
- VL.2D.CurveFitting by motzi
- VL.OpenWeather by sebescudie
There've also been some updates:
- There was an update by the FUSE team at the last meetup
- VL.IO.RCP as shown at the meetup

If you haven't heard of vvvv yet: It is a visual live-programming environment that accompanies you from prototyping to final production. Here is what vvvv can do for you.
If you haven't heard of the Prototype Fund yet:
You can apply for our current application round until March 31, 2021 (11:59 p.m.).
As individual developers or small interdisciplinary project teams, you will receive up to €47,500 over six months from the Federal Ministry of Education and Research. With this funding, you can write code and develop a first prototype of your software. In addition, we will connect you with tech and other relevant communities, support you with coaching, and advise you on project implementation and communication.
Who can apply?
Self-employed developers and small teams who live in Germany can apply for funding.
Open Source
Your results must be made publicly available under an open source license.
For inspiration, here is a listing of previously funded projects.
And here are some reasons to use vvvv for your Prototype Fund project:
- The visual live-programming nature of vvvv means that it is especially good for quickly iterating on prototypes
- You can now create standalone applications to distribute results as Windows apps
- FOSS development with vvvv does not require a commercial license and thus is entirely free without any limitations
- The friendly community will most likely be able to help you out in case you get stuck
Let us know what you're working on. We'd love to hear from your projects!
Dear patchers,
this is vvvv beta 41, with mostly 3 changes over the previous release:
- Now includes VL 2020.2.6
- A fix for troubled BezierEditor nodes
- A fix for problems with red Mouse nodes
Offline Installers
32bit Version: core addons
64bit Version: core addons
In the course of our festival opening ceremony 2021, our international jury will select the winners of the VRHAMMY Award, which is endowed with 5,000 €.
Show them what you're patching with!

That was it for January. Anything to add? Please do so in the comments!
Here we go!
We have a candidate for our upcoming release:
This is going to be the first stable release including the huge shiny new 3d rendering library we created based on the Stride Engine!
For more details of what's new, please consult the Change Log.
So please test and report your findings. If we don't find any complete show-stoppers within the next days, this is going to be it!
Here is to let you all know about the existence of MediaFutures. In a nutshell:
...
MediaFutures funds and supports products, services, artworks and experiences that transform for the better the ways people consume news and engage with facts, and the ways experts make decisions and contribute to society.
...
MediaFutures will support 51 startups or SMEs and 43 artists through a total of three Open Calls in the coming three years, distributing a total amount of €2.5M. It will support the selected applicants through a 6-month acceleration (startups & SMEs)/ residency (artists) programme including funding, mentoring and training.
If you're interested, checkout the details for the 1st open call which is closing on January 28!
This info is from their FAQ regarding who is eligible in the calls:
- The Member States (MS) of the European Union (EU), including their outermost regions;
- The Overseas Countries and Territories (OCT) linked to the Member States;
- H2020 Associated countries: according to the updated list published by the EC
- The UK applicants are eligible under the conditions set by the EC for H2020 participation at the time of the deadline of the call.
Note that individual artist applicants will be eligible from any country in the world provided that they are able to travel to Europe for the MediaFutures programme and always provided that Covid-19 situation allows it.
On short notice: They have a webinar on January 13, 1pm CET to learn more about the program.
Hope some of you have an idea to apply and if your idea involves vvvv, don't hesitate to get in touch. It may be worth to explore opportunities together...
Hello everyone!
Here is the second big release this year for vvvv gamma! Available for download and purchase. Now!
It comes with improvements that strengthen the toolkit character of vvvv gamma and VL, which are outlined over here: vvvv-the-tool.
It also comes with small improvements for object-oriented programming patterns by introducing the This node. Many of those changes were motivated to be able to roll out a certain library. So this is the last version without that exact library.
Bugfix releases:
- 2020.2.2 on October 1st, 2020
- 2020.2.3 on November 17, 2020
- 2020.2.4 on November 25, 2020
- 2020.2.5 on January 8, 2021
For the full list of changes, see the The Log of Changes.
Updating libraries
This release introduces a breaking change for certain NuGet packages! If you use any of the following packages then you'll have to make sure to use the latest available version:
- VL.OpenCV
- VL.Devices.Kinect2
- VL.Devices.AzureKinect
- VL.Devices.AzureKinect.Body
- VL.Devices.Nuitrack
- VL.Devices.RealSense
- VL.MediaFoundation
- VL.Elementa -pre
- VL.Audio -pre
- VL.IO.OSC -pre
- VL.RunwayML -pre
So when updating to 2020.2.x you need to update to the latest version of these libraries. See Manage Nugets on how to do so via command-line.
Running 2020.1.x on the same machine
If, after running 2020.2.x and updating the above libraries you want to run 2020.1.x again, you'll have to make sure to first remove the new packs that are only working for 2020.2.x.
To do so, you'd go to your
AppData\Local\vvvv\gamma\nugets
and either delete packs selectively or simply clean the whole directory and re-install NuGets as you need them.
Info for library developers
This breaking change only affects your library if it is using a CSharp-project that is referencing VL.Core! In this case, all you have to do is to update VL.Core to 2020.2.x.
Then please communicate which version of your library is compatible with which version of vvvv.
Sorry for the inconvenience, we hope to make it up soon, by sharing a certain library...
Happy patching & see you soon,
yours devvvvs!
Previously on vvvv: vvvvhat happened in November 2020
So,
December happened and what not happened is the planned release of 2020.3, the first stable one including the shiny new 3d engine VL.Stride, as planned. We're in the final commits for it, so please bear with us and just get a preview if you can't wait.
Meanwhile, the promised rework of the OSC and TUIO nodes has landed in previews, which should make it the easiest ever to work with those two ubiquitous protocols.
Working Groups
I think it makes sense to start giving you an overview of a few bigger community efforts that have recently started. Please add your expertise where you see fit! Hoping we can gather some regular updates from them in the coming months:
- The FUSE project is building GPU tools and libraries to use with VL.Stride. You can support them here
- The Universal Skeleton Bible is meeting for the first time next week
- A new VL.ML chat room just opened to discuss all things vvvv and machine learning
Contributions

Updates:
- VL.OpenCV meets VL.Stride by ravazquez

After NODE 2020, having seen all the wonderful things Stride and vvvv can do together, it was inevitable to fall head first into the adventure that has been bringing Stride and VL.OpenCV into a playful and seamless friendship.
I am happy to announce that as of version 1.2.0 of VL.OpenCV, you can effortlessly and painlessly:
Find your camera's position based on a pattern or marker
Need to know where your camera is and what it's looking at based on an Aruco marker or a chessboard calibration pattern?
Say no more:
And now from the outside:
Dizzy yet?
Estimate the pose of an Aruco marker to create AR applications
Bring 3D objects and animations into your image using Aruco markers to create augmented reality projects:
Calibrate a projector
Remember this beauty? It helps you figure out the position and characteristics of your projector in your 3D scene.
And reproject
Once you know where your projector and the spectator are, you only need to worry about the content. 3D projection mapping made easy!
Not bad huh?
So there you have it boys and girls, 3D computer vision based adventures for all! Head to your local nuget distributor and grab a copy while it's still hot.
A big thank you to motzi, gregsn and tebjan for their invaluable help as well as to many others who contributed one way or another.
And as always, please test and report.
Keep your cameras calibrated kids!
Happy holidays!
