Here is to let you all know about the existence of MediaFutures. In a nutshell:

MediaFutures ... brings together startups, SMEs and artists in the media value chain to expand on standard models and comes up with unconventional ways for people to engage with quality journalism, science education and democratic processes. It aims to create products, services, digital artworks and experiences that will reshape the media value chain through innovative, inclusive and participatory applications of data and user-generated content.

...

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:

Only applicants legally established, and working, in the case of groups of individuals, in any of the following countries will be eligible:

  • 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!

2020.2

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:

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:

Find camera position and rotation based on Aruco marker 2

And now from the outside:

Find camera position and rotation based on Aruco marker 2

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:

AR Teapot

Calibrate a projector

Remember this beauty? It helps you figure out the position and characteristics of your projector in your 3D scene.

Calibrate projector

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!

Reproject

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!

Here is,

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:

OSC

Receiving OSC messages

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:

  • i: Integer32, h: Integer64
  • f: Float32, d: Float64
  • s: String, c: Char
  • r: RGBA color
  • b: blob byte[]
  • T: true, F: false

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.

Sending OSC messages

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!

TUIO

Receiving TUIO data

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.

Sending TUIO data

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!

Who Natan Sinigaglia / dottore | Kyle McLean / everyoneishappy
When Mon, Dec 14th 2020 - 21:00 until Mon, Dec 14th 2020 - 22:00
Where Online, hosted by the NODE Institute, Germany

Hello vvvvorld!

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 :

  • Domain specific high level node collections
 ○ Distance Fields & Raymarching
 ○ Particles
 ○ Procedural Geometry
 ○ Textures and Materials
 ○ GPGPU
  • A domain agnostic set of nodes and helpers for patching GPU logic
  • A clean collection of abstract shader functions that can be easily referenced for coders

Intended to benefit the community and wider ecosystem :

  • Free and opensource
  • Well documented
  • Produced in collaboration with the VVVV group to iterate and improve on the core shader based workflows and approaches of VL.Stride.

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.

The event is kindly hosted by the NODE Institute.https://thenodeinstitute.org/event/the-fuse-project/

Best regards,
Natan & Kyle

Previously on vvvv: vvvvhat happened in October 2020


November!

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!

Colors for nothing and shadows for free!

If you haven't yet, watch the recording of the last vvvv meetup where, among others, we have texone show us how he already takes VL.Stride to the next level...

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!

So once again, where were we...

oh, NODE20 just happened and never mind if you missed it, you can still access the recordings of all workshops!

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.

vvvv gamma 2020.2 is out and also the latest previews for beta41 already include the 2020.2.x branch of VL!
