VL: New OSC and TUIO nodes

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!

FUSE VL.Stride GPU tools presentation

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

vvvvhat happened in November 2020

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!

vvvvhat happened in October 2020

Previously on vvvv: vvvvhat happened in August 2020

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!

This was NODE20

Probably,

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.

The keyvisual by artist duo a_a_a_a and mburk calmly meandering in the form of an AR manifestation in most of the studio broadcasts.

TV Shows

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:

  • The Emergency Broadcast Studio - Behind the Scenes, where readme talks about how he and bjoern took on the brave task of running the AR studio on VL.Stride, which was still very much in the works when they started...Must watch to get an impression of the effort of what was behind the studio setup. Credits also go to kopffarben who helped running the actual shows in the end!
Backstage at the EBS

Workshops

Massive thanks go to the whole team of The NODE Institute who ran the workshop and streaming operations on the ground together with: ravel, sebescudie, Rayment, katzenfresser and Ben Schiek.

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.

The good news: Even though now that NODE is over, you can still access the recordings of all workshops!

Support

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!

NODE20 Workshop Recordings Online & ...

vvvvolks. What a node!

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:
https://forms.gle/tMiVEMkQL89NMnKu8
You can help to make NODE better by filling this out. Thank you so much!

The recordings

Many have asked us for the workshop recordings. And here are some good news:

  • For those who attended NODE20: please go ahead and login to NODE20 on Talque to review the workshops there.
  • For those who did not attend but want to learn the same: We have bundled all the recordings into one course at the NODE Institute, which you can buy for 50 Euros only. 30 workshops, 90 hours of learning. Its massive!
https://thenodeinstitute.org/courses/node20-vvvv-workshop-bundle/

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.

Thank you !
David for The NODE Institute and Festival Team

VL.Stride for evvvveryone!

The long wait is over!

vvvv gamma 2020.3 public previews now include VL.Stride, the new 3d rendering library, based on the opensource Stride 3d engine. You be the judge, but spoiler: this is rather huge!

Download vvvv gamma 2020.3 preview

Massive thanks go out to all early accessors who helped us uncover and fix countless buggers that you no longer have to run into. So this is also on your behalf. You're welcome!

Status

All of the basics are now in place. Find your favorite among these:

  • Primitives: Plane, Box, Sphere, Cylinder, Cone, Capsule, Donut and Teapot
  • Instancing: Via spread of transforms, other entities or buffers
  • Lights: Ambient, Directional, Point, Spot, Projector, Skybox
  • Shadows: On by default, configurable in quality/resource-consumption
  • Materials: Highly configurable PBR workflow through a large set of nodes, incl. easy normalmapping, displacements,...
  • Textures: From file, video, Spout, Skia, HTML or renderer
  • TextureFX: Basic selection available, more to come
  • Texture Feedback: Yes please!
  • Texture Readback: Absolutely, think pipet,...
  • ShaderFX: Experimental nodes to patch shaders visually
  • PostFX: Highly configurable via set of nodes, think: depth-of-field, bloom, ambient-occlusion, ...
  • Dynamic Meshes: Generate meshes using vertex- and indexbuffers on CPU
  • Shaders: Pixel, Vertex, Geometry, Compute. Write your own using full syntax highlighting in VisualStudio with hot-reload
  • Assets from file: Load textures and models directly from file
  • Assets from Stride Game Studio: Prepare assets and complete scenes in game studio
  • Windowing: Easy handling of multiple windows (and cameras)
  • Misc: Render Skia and HTML content directly onto the screen (ie. no texture-pass needed)

To give you an idea, here is a random collection of screenshots of what earlyaccessors have created with this already.

Still missing

To give you a heads-up, here are things you might expect already but are yet to come:

  • Loading models does not bring all their materials and animations in yet. To get a models materials showing automatically, you need to load them as an AssetModel via an extra Stride project. Animations are not yet supported.
  • Simple Text Rendering: for now best done via Skia or HTMLRenderers
  • Physics nodes are available in the Experimental section, meaning you can use them but still we want to give them one more round of refinement
  • VR support is still to come. Stride supports it, we just haven't exposed it yet properly
  • Things you'd do with the most popular contributions InstanceNoodles, DX11.Particles and FieldTrip are still missing a corresponding functionality

And then some more, but the above should be the most obvious ones you'll stumble upon.

How to get started?

Open the Helpbrowser (F1) and check out the explanations, howtos and examples. Remember the preview status, ie. those are not yet in their best shape. But they should help you find your way.

And if you really got nothing better to do in the week of October 2nd to 8th, then consider joining us for NODE20 where we have the following series of workshops dedicated to getting you started with VL.Stride:

A tickets costs 50€ and gives you full access to all of the above and so many more workshops and their recordings.

Pro-tip: This is a so-called no-brainer!

Thanks

A couple of people believed in the development of VL.Stride from the beginning and substantially supported its development. We bow before you:
