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:
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:
Bring 3D objects and animations into your image using Aruco markers to create augmented reality projects:
Remember this beauty? It helps you figure out the position and characteristics of your projector in your 3D scene.
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!
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!

Where Online, hosted by the NODE Institute, Germany
We (Natan Sinigaglia / dottore | Kyle McLean / everyoneishappy) would like to give you a heads up on a project we are undertaking in these times that we would hope should be of some inspiration and enthusiasm for the beloved VVVV community!
The FUSE project will provide a well researched collection of GPU tools and libraries to use with VL.Stride :
○ Distance Fields & Raymarching ○ Particles ○ Procedural Geometry ○ Textures and Materials ○ GPGPU
Intended to benefit the community and wider ecosystem :
We are presenting this project in greater detail on 14th Dec 2020 at 21:00 CET to studios and individuals who are interested in the graphical future of vvvv gamma.
Project Info: vvvv.org/fuse-project
The event is kindly hosted by the NODE Institute.https://thenodeinstitute.org/event/the-fuse-project/

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.

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.
