Who sebescudie, joreg
When Tue, Mar 3rd 2020 - 19:00 until Thu, Mar 5th 2020 - 21:00
Where SUPERBIEN, 14 rue Crespin du Gast, (M Ménilmontant - Rue Saint Maur), Paris, France

D'accord Paris,

while I'm in town for a vvvv meetup on March 1st and a presentation at Ircam on March 6th, I thought we could fit in some workshops. So together with local hero sebescudie of SUPERBIEN we'll run two workshops. Here is for you to choose:

Getting started with the all-new vvvv gamma

Are you a creative coder, interaction designer, media artist, maker or scientist and want to add a new tool to your toolbox? Are you afraid of coding and want to try visual programming instead? Have you heard of vvvv before but never found the time to get started? Or are you just lazy and want to get your things done more efficiently? This workshop is for you!

vvvv is a visual programming environment that allows you to realize ideas involving things like 2d/3d animation, computer vision, MIDI, OSC, DMX, Kinect, Leap,... quickly without the need to write any code. But if you want, you can also write C# code for it and use any .NET library with it!

In this 3 hour hands-on workshop we'll give you an idea of how it feels to work with vvvv. You'll learn the fundamentals that you need to be able to follow further workshops or take the next steps on your own.

When: Tuesday, March 3rd, 7pm-10pm
Where: SUPERBIEN - 14 rue Crespin du Gast (M Ménilmontant - Rue Saint Maur).
Signup: It is free but seats are limited, please signup via: ping@sebescudie.fr

vvvv gamma for vvvv beta users

If you're a user of vvvv beta and want to up your game by learning about VL and moving on to vvvv gamma, this workshop is for you! Here we'll assume you're familiar with the terms of vvvv and know how to handle a 3 button mouse.

We'll take you by the hand and try to convince you that VL and vvvv gamma are your best friends moving forward. You'll learn about the basics and benefits of using an object-oriented approach to solve certain problems and get an overview of all the improvements vvvv gamma offers over what you're used to with vvvv beta.

When: Thursday, March 5th, 5pm-9pm
Where: SUPERBIEN - 14 rue Crespin du Gast (M Ménilmontant - Rue Saint Maur).
Signup: It is free but seats are limited, please signup via: ping@sebescudie.fr

Oui oui, hope to see some of you there. And please spread the word to anyone who could be interested in this!

When Wed, Mar 4th 2020 until Fri, Mar 6th 2020

Looking forward to presenting vvvv at this years Ircam Forum. With Ircam being the birthplace of both Max and PD, which quite inspired vvvv initially, it will be a great honor to hopefully give some inspiration back.

Here is what it is generally about:

Whether you are a musician, sound engineer, designer; Whether you work in research and development on new technologies; Whether you are a teacher or student, professional or just an aficionado, you are welcome to join us at this annual meeting at IRCAM, Paris.

My talk is on Friday, March 6th, 11h45 - 12h15 and and here is the full list of this years speakers.

Hope to see some of you there!

Previously on vvvv: vvvvhat happened in December 2019


Meanwhile,

work continues as per the usual on our quest to release a smooth vvvv gamma 2020.1 within Q1. Previews are coming out about once a week now. Most recently we introduced another improvement for help patches.

We have a progress report on VL.Xenko out and in parallel, we're also working on a ContributionManager for vvvv beta, which is ready for a test-drive now.

Into numerology? You may be interested in last year's numbers and figures.

And if you're up for meeting your fellow patchers in real-life, make sure not to miss our upcoming intro workshops, meetups and patching circles in Berlin. Here is the stream of our most recent meetup where we heard news from ur-patcher sunep.

Help!

One of the most requested features for VL ever since was the support for help-patches. Obviously they had to come back, but it took us a while to figure out how exactly. One of the brainstorming sessions at LINK was especially helpful to sort out the details. Thanks everyone for your input...

Help Patches

So for the user it is just as before: Press F1 on a node that you need help for. Now what happens is:

  • If a help-patch is found, it is opened and a bubble indicates the node you were looking for
  • If no help-patch was found, a bubble indicates that no help-patch was found
Help patch was found...
No help patch available...

In both cases, you can now optionally opt-in for more help: Click the bubble to open the help browser showing the nodes Node Info.

Node Info

Shows some info about the node plus 3 lists of how-to patches this node is used in:

  • most relevant (the dedicated help-patch)
  • still relevant
  • list of other patches using this node (automatically generated)

This should increase the chance of finding good info about how a node can be used in different scenarios.

When "follow mode" is active, you can click around in the patch and always get the node info to the last selected node.

Help Flags

Creators of libraries who want to provide help patches now use help flags to indicate relevance for a node. Read all about using help flags in the graybook.


Available for testing in latest previews!

Fantastic!

is probably not exactly the word you'd use to describe vvvv's 2019 numbers. If you can't handle bumpy roads, please set your Damper to ~2s before reading on... Not sure what this is all about? Check out last year's numbers of 2018 to make yourself familiar with this vvvvery tradition. Then pull yourself together:


Webwise

While we still don't have any new numbers from vvvv.org itself we do have what the forum tracks. It shows us different statistics regarding user engagement over time that are generally, how can I put this... not improving recently. The most uplifting I found was this:

DAU/MAU - daily divided by monthly active users

According to the description of the graph, this indicates your stickiness in % and 30% is to be aimed at. Even though overall fewer things are happening on the forum you keep sticking around. Who could blame you, after all, it is rather cozy around here. Here is another one that doesn't look all too bad:

Page Views

Ignore the red ones (crawlers) but see the rather constant number of logged-in users (dark blue) and the curious spikes at the end of December from anonymous users (light blue). Are these already the harbingers of numbers to expect when we finally will have an official 1.0 of vvvv gamma out? (hums) Dreams are my reality...

Not really numbers, but still interesting, here is a listing of top forum search terms in order of your priority:

realsense, kinect, image compare, orbbec, dx11, ndi, kinect2, arduino, opencv, zgl, osc, gamma, particles, dmx, addflow, superphysical, midi, /logstartup, fbx, audio, face, skia, touch, dds, projector, text, scroll bar, firmata, fieldtrip, ilda, linux, leap, point cloud, camera, csv, yolo, artnet, tracking, html, mac, fluid, svg, texture, laser, leap motion, contour, gif, websocket

Downloads

2010 2011 2012 2013* 2014* 2015* 2016* 2017* 2018* 2019*
vvvv beta releases 4 3 5 5 5 4 1 4 8 1
core 45.700 32.100 36.000 45.000 42.500 38.000 29.300 32.600 61.700 22.000
addons 10.700 14.400 18.800 29.000 28.500 25.200 19.400 21.400 38.800 11.000

* x86 and x64 combined

What can we say? Only 1 release was really lame. But was it? Ok, yes, it was, but the way I'd like to whitewash these numbers a bit is that they are only reflecting vvvv beta, when obviously most of our work (to some of your's concern) went into VL and vvvv gamma. And inconveniently we don't have any numbers for vvvv gamma downloads at all. But then again those wouldn't be high numbers also because as you know we're still keeping a rather low profile with vvvv gamma, mostly advertising it to you as long as it is still in preview. So anyway, nothing to be particularly proud of here. Moving on...

Licenses

vvvv.org income through licenses and dongles sold

Phew, not as bad as the declining number of downloads would have suggested. Certainly not an upwards trend but still the 4th best result so far. So let's see what this number is composed of:

2011 2012 2013 2014 2015 2016 2017 2018 2019
countries 19 18 17 17 21 19 22 19 17
companies 52 61 69 81 102 90 80 77 63

Mkay, so according to the number of individual commercial users we're basically thrown back to 2012. Quite a bummer but to be expected when you put most of your resources into R&D for the shiny new product that just still isn't there yet to make its own money. We were certainly hoping to keep a few more of you with our advances in VL but we know that before making any new friends, VL needs to grow out of vvvv beta and get a 3d engine...


That was it? Far from! This year we held by far the largest number of workshops for onboarding new users. These included a series of 8 free introductory workshops and 8 full-day workshops on various topics in Berlin. Further, we toured Kiel, Linz, Timișoara and Moscow. Also, we held 10 meetups and 3 patching circles in Berlin, one meetup in Hamburg and one in Moscow. Finally, we even held a dedicated Teaching Patching mini-conference to better understand the needs for vvvv in education.

All these activities will see a continuation in 2020 and culminate in NODE20 in October. Until then, the road to NODE is filled with some precious gemstones:

  • The first official release of vvvv gamma that you can finally own for money, already available for preview
  • Initial release of 3d engine for vvvv gamma, still work-in-progress
  • Polished libraries to support your basic needs
  • More workshops and learning opportunities

Is 2020 finally the year of the future of visual programming or is the world not ready for VL yet? Stay tuned, spread the word and become part of a truly wonderful new numbers blog post next year! You know what to do...

We wish you what!
Yours,
vvvv.

Helo evvvveryone,

We're starting into 2020 with a couple of activities, culminating in the recently announced NODE2020 happening in October. So leading up to that, here is what we got for you in the first quarter of this year:

Intro vvvv gamma workshops

Every fourth Tuesday a month we're running a vvvv gamma intro workshop for total beginners. It goes for 2 hours and gives participants an idea of how it feels to work with vvvv gamma. Here you learn the fundamentals that you need to be able to follow further workshops or take the next steps on your own, continuing with online learning resources. Spread the word, send your friends and family!

Available dates:

  • January 28, 6-8pm
  • February 25, 6-8pm
  • March 24, 6-8pm
  • April 28, 6-8pm

The workshop costs 5€ and you can sign up here.

Meetups

Right after every intro workshop, meaning also every fourth Tuesday a month, starting 8pm, we're running a vvvv meetup. Here we count on you: Have a project, demo or new library to show? Just come with your laptop and present. Low profile, no pressure. Doesn't need to be polished, rough around the edges is very welcome! Or just grab a drink and lean back...

Patching Circles

The patching circle is a vvvv support group. Once a month, every second thursday, we're meeting to help each other out and find collaborators for our projects. So please join us for patching and drinks if you...

  • are stuck in your patches and could use some advice
  • want to help others with your experience
  • just want to click yourself away in a patch-friendly atmosphere

If you feel like coming to a meetup or patching circle, please announce your participation in our getogether events.

All the above are happening at the cozy NODE Institute, Wipperstrase 13 in 12055 Berlin/Germany. If you're running a similar event, be sure to also post an announcement here in the blog to get the attention of your local vvvvriends.

Update: This is now publicly available at: http://visualprogramming.net

Happy new year, evvvveryone! Welcome back and we hope you had some fine holidays. More than one year has passed since the last report. An update is well overdue. This post sums up last year’s (2019) progress on our upcoming 3d engine for vvvv gamma.

Xenko’s codebase is huge and even after one year, we are still in explorer mode. But help is near! As you might have read, Xenko’s lead developer Virgile Bello aka xen2 is now with us in Berlin. While his main focus is maintaining Xenko and building a community around it, he also helps us to achieve our goals faster by answering questions and fixing bugs that we encounter.

As it is still early, for each technology we work on, we try to focus on creating only the basic nodes required to get a working prototype. Because if we have to change something fundamentally, every node has to be adapted. Nevertheless, there are tons of nodes already.

The videos and screenshots in this blog post are mostly early development captures. Things will change and improve over time.

Besides many little things, here are the main topics we worked on:

Scene Graph

The scene graph is the fundamental data structure of the 3d engine. It contains the entities and scenes of your application. Most engines use a tree view to visualize and work with it. In vvvv, we have “Group” nodes to build the parent-child relations of entities.

For convenience, every group and entity got a transformation and name input. The name becomes handy for finding and accessing certain entities later programmatically or just for getting an overview. It also shows up in the tooltip.

Scene Graph Explorer

The scene graph can become large and complex quite quickly. Especially when you are a brave patcher and you use sub-patches to stay organized. Sometimes you want an overview of the whole tree structure and see basic properties (at runtime, of course!). Luckily there was an older project for Xenko that traverses the entity tree and visualizes its components and properties.

We updated it to the latest Xenko version and imported it as a debug helper.

Materials

If you look at the options and properties of a material in Xenko it’s quite complex and some features require expert knowledge. To make things quick and easy, we made a few simple nodes to cover the basics.

We’ll also add texture-based versions of them and for more complex setups, you can always design the material in Game Studio and import it.

Runtime Asset Loading

For almost every project you have to import content. Be it images, videos, models or just text files. This sounds trivial at first, but as you come closer to deployment, it gets more tricky to have everything at the right place. Even more so, with the new executable export in vvvv gamma.

Game engines usually solve it like this: Resource files like models, textures, etc. get imported via the editor and compiled to runtime assets. These asset files get placed next to the executable on compilation. This works well for static assets, but for rapid prototyping and changes at runtime, we need something more flexible. So we took the Xenko asset builder and adapted it to work at runtime. This allows for importing and building assets while the application is running.

File Assets

Load single resource files directly from disk, aka FileTexture. Good thing is, this works together with Xenko’s asset database and caches already loaded files. So everything is pooled by default.

Load Project

That’s a nice one, you can create a Xenko project in Game Studio, work on Assets, Scenes, Prefabs, etc and import everything at once with the LoadProject node. It even updates on save!

Modify Imported Entities

Since we work directly with Xenko’s data types, imported entities are in no way different from patched ones. You can access and modify them in the same way:

Shaders

vvvv is known for treating shaders first class. The Xenko team seemed to have a similar attitude. They created their own shader language called XKSL. It is a superset of HLSL, so you can paste shader code from vvvv into an xksl file.

However, there is much more. They added quite unique features that make writing shaders easy, fast and clean. If that wasn’t enough, you can compose shaders with other shaders at runtime and avoid an explosion of shader permutations.

TextureFX

The well known TextureFX node-set in vvvv beta makes working with textures easy and fun. Of course, we want to have the same experience in vvvv gamma. But, with preview in the tooltip! There you go:

ShaderFX + FieldTrip

Visual shader programming with nodes? Yes, please! The composition feature of XKSL makes this easier than expected. Turns out, the Xenko team was working on something similar which made it relatively easy to build a node-set around it.

To test these nodes, we had the pleasure to have Kyle McLean in our office for some days and worked with him on porting FieldTrip nodes to VL.Xenko.

FieldTrip is a modular shader library Kyle McLean created for vvvv beta. It includes raymarching and general tools to work with scalar fields and vector fields on the GPU.

We ended up with a working prototype, as you can see in this video from the vvvv berlin meetup:

StreamOut Instancer

Since Xenko has no native instancing for their material shaders yet, we tried to use stream out aka transform feedback to transform a mesh multiple times and build one big vertex buffer that works with the Xenko material pipeline. The node works nicely and takes a Mesh, a material, and the instance transformations. You can easily draw a few thousand instances with it. The header image was mostly done with it.

Profiler

The bigger your project gets, the more important it is to know how well your shaders perform. Thanks to Xenko’s profiler infrastructure we can give every shader a profiler key and see it listed in the GPU page:

Next Up

There are still some topics left in order to make VL.Xenko as convenient as we like it to be.

Multiple Windows

One major feature that vvvv beta does exceptionally well is working with multiple windows. Games are usually focused on one output window. In order to get this to work, we have to find a solid way to instantiate multiple windows in Xenko and render content into them. This requires some coding behind the scenes. We are planning to get this done by early 2020.

One-Click Installation

At the moment one still needs Visual Studio to set up a VL.Xenko project. This should, of course, be just a one-click package installation as we have it with other VL libraries. Initial tests went well and we are confident that this will work out just fine.

Rename to Stride

Because of legal reasons about the trademark, Xenko has to do a re-branding and will be called Stride soon. We'll of course follow along and will rename the library to VL.Stride.


As much as we want everyone to try it, it won’t make much sense to share the library in its current state. The setup process needs developer knowledge and a few main features are still missing. But stay tuned for more on that!

If you want to know more about something specific or have any remarks or requests, don't hesitate to leave a comment below.

That’s it for now, looking forward to NODE20 and more exciting patches in 2020.

yours,
devvvvs

Previously on vvvv: vvvvhat happened in November 2019


okok,

still no bigfat vvvv gamma release but we're now really getting close. See what we've just released last month:

This means we're now basically feature complete and are planning for an initial release in Q1.2020! More tweaks and fixes will happen for the export and we'll do some more work on the help browser to make it even more useful. Meanwhile please keep reporting your buggers and help us make this a solid first release.

Documentation-wise there've been three updates: A new Section on IOBoxes in the gray book and two new how to videos:

And the biggest news of all: NODE20 is happening! Just in time so that we'll have 3d-support in vvvv gamma and hopefully finally match most features of vvvv beta. Ideally we'll have at least a first version of VL.Xenko out before, so that some of you can even already prepare workshops with it... Curious about our progress there? Expect a separate blogpost with a wrap-up of latest developments shortly.
