Where The#Brake, Valentinskamp 28 A-B, 20355, Hamburg, Germany
Hamburgers!
For the first time in world history (?) there'll be a vvvv meetup in your parutiful city. We'll be hosted in the workshop of The#Brake! There'll be a projector and drinks, that is all we need to get cozy.
We're happy to have long time vvvv users DECODE demo one of their latest projects. But there'll be enough time to hear more, so please bring your projects and show everyone what you're patching on!
From our side expect a little update on latest developments regarding the vvvv gamma preview
If you feel like, please RSVP.
Looking forward to seeing you!
Previously on vvvv: vvvvhat happened in July 2019
What's been the happenings?
Glad you aks! First off: Mid August saw the 2nd incarnation of the LINK summercamp. This time organized by StiX near Bratislava. He wanted to write a little report of our activities there so I'm not gonna spoil it. Only wanna say so much: It was a blast! We cannot thank StiX and his friends enough, who did all the organization and prepared all the amazing food. Chapeau! And I wittnessed talks of possible future LINKs in france and spain. Let's see who gets this done first...
Then we just released a new vvvv gamma preview which finally includes nodes like the MultiFlipFlop, a Switch with multiple inputs, Resample nodes and more... Otherwise we're still polishing executable export and hope to be able to give you a preview of it soon. Besides that VL.Xenko is progressing quite well. More interesting for developers, read about how we switched to Xenko.Math and a more popular one:
As I hope you've noticed already, we've been strong on education lately: We're now offering personal training including a desk in our studio in Berlin: vvvv Training at the Source and we have regular activities going:
Upcoming dates

Free vvvv gamma introduction
Wanna get a taste of the all-new vvvv gamma? Join us from 6pm to enjoy a 2 hour introduction to the future of visual programming!
If you feel like, please rsvp on our Gettogether page!
In preparation for the Xenko game engine integration we decided to change the default math library of VL from SharpDX to Xenko. The decision was particularly easy since both math libraries have the same origin and most types and methods are identical. And thanks to the VL import layer it's easy to switch out the types, without any noticeable changes for the VL user.
What you get:
- Existing VL patches will continue to work as before
- No conversion needed when working with Xenko
- Faster matrix uploads to GPU (see below)
Trivia
We are (again) in luck with Xenko since it just so happened that Alexandre Mutel, who developed SharpDX, was a core developer at Xenko. We actually didn't know that at the time we started to work on the VL core library. We chose SharpDX mainly because it was well established, complete and open source. So it was quite a nice surprise when we browsed the Xenko source code for the first time and saw that they basically use the same math code.
Download
Here are direct links to the latest preview versions:
vvvv gamma 2019.1 preview 624
vvvv_50alpha38.2_x64
addons_50alpha38.2_x64
Technical Details
This section is only relevant for library developers.
Transposed Matrix Memory Layout
Xenko's 4x4 matrices have a transposed memory layout compared to SharpDX. This is not to be confused with transposed matrix elements (M11, M12, M13 etc.), it is only relevant when doing low-level operations with memory and pointers, such as uploading them to the GPU. The big advantage of it is, that Xenko's matrices can directly be uploaded to the GPU without the overhead of transposing them.
Changes on C# Projects
Most C# projects written for VL don't need to be changed. Only if they use the SharpDX.Mathematics nuget to work with vectors, matrices, rectangles etc.:
- Must switch to Xenko math
- Must use the new SDK style project format
In order to transition your C# project to Xenko, remove the SharpDX.Mathematics nuget and install Xenko.Core.Mathematics instead. Then change the using statements in the C# files:
//old: using SharpDX; //new: using Xenko.Core.Mathematics;
If you then get an error on compilation, your project might be in the old format. Upgrading is quite easy, it just involves changing the header and deleting most lines in the project file. Follow this guide or join our chat if you need help.
Please give the new version a spin and send us a report if anything doesn't work as before.
Happy calculations!
Yours,
devvvvs

Finally,
a new vvvv gamma preview is out including the promised tooltip rework. Please help yourself to a fresh copy, test and report your findings. Up next as promised: executable export. And I'm happy to report that we're back in the game! After a major internal rewrite of the backend, which became necessary because we found a last minute showstopper shortly before we wanted to release a few months ago, we're now back where we were: We can export most patches/projects to an executable at the click of a button. It is painless and gorgeous and we can't wait to share it but still a few things need sorting. Meanwhile, here is how it looks at the moment:
At the same time, when our team is running in overdrive to make all the pieces fall into place we get people wondering Is vvvv dead yet? which swiftly turned into the 17th of the most active topics of all times...
Speaking of activities, here what's happening in August and September in Berlin:
- Every 2nd thursday of the month: Patching Circle - a hands-on vvvv self-help group
- Every 4th tuesday of the month: vvvv meetups
- Always before each of the above: Free introductions to vvvv gamma
- 5 dates: Full day workshops on different topics
...to be continued in the months ahead
If you wanna help, please spread those news, run meetups, patching circles or workshops in your own city and let us know about them. And also, if you have a moment for brainstorming, please help us with this Call for tutorial topics.
Contributions
Not so much on the contribution front last month, except one outstanding piece by dottore:
VL.Animation.ParticleSystem which comes with a series of not-to-miss video tutorials.
And two more in the work-in-progress section:
Jobs
And as always if you're looking for a vvvv job or even have one to announce, remember these:
- Worldwide jobs via our forum
- Worldwide jobs via Interactivejobs.io
- Jobs in Germany via Das Auge
That was it for July. Anything to add? Please do so in the comments!
Once a month, every second thursday, we're hosting a "patching circle". Please join us for drinks and patches if you ...
- ... are stuck somewhere with a project and could use some advice
- ... are just getting started and want to know what it`s all about
- ... just want to click yourself away in a patch-friendly atmosphere
vvvv devs and other members of the community will be there to help and share their experience.
Wipperstraße 13 is our new space - for asking questions, collaborating and keeping yourself on your personal level of superhuman programming skills!

Any questions?
Here we go!
As mentioned previously, an update to how tooltips look and work, was one of the two main things missing before we call vvvv gamma a 1.0 release. And they have just landed in the preview, horray!
Previously tooltips where text-only, rendered all in one style and often contained rather cryptic information. Now we have structured information that is nicely presented and we also tried to replace weird messages with human readable text where possible.
Nodes
Tooltips on nodes foremost show the nodes full name and category plus its "Summary" and "Remarks" help information in two separate paragraphs. Additionally, if available you'll see timing information, ie the amout of time the node needs to execute. Operation nodes can also show you the name of the operation they are currently executed on.
In case a node has an error or warning, we try to help you understand what's going on by answering the following three questions:
- What is the problem we see?
- Why is this a problem?
- How can you deal with it?
- In case of warnings: When can this warning be ignored?
Also, while a warning/error tooltip is visible, pressing CTRL+C copies the message for convenient pasting, eg. in the forums.
Pins
Tooltips on pins foremost show the pins name and datatype. For for primitive types (like numbers, strings, colors,...) that can easily be displayed, we also show the current value.
In cases of collections (like spread), we also show the current count and again, if the datatype is displayable, we now show up to three slices, as compared to the previously only one.
Oh, and the obvious:
Links
Tooltips on links are by default only visible, if the link has an error or warning. To get a tooltip showing on normal links, to see their datatype, press CTRL while hovering it.
Scaling
Zooming patches is nice, but we figured independent of that, we also want to be able to define the size of a tooltip. so zooming tooltips it is:
Explorer
Also the patch explorer got a bit more informative using the new tooltips.
Nodebrowser
Same goes for the nodebrowser, which should make it easier to find the right node as the summary and remarks are now much more pleasant to read.
Settings
And finally, there are a now a couple of more settings to tweak for tooltips:
- Classic: enable to go back to the old style tooltip
- Scaling: default value for the tooltips size
- ShowAdvancedTimings: make process nodes show timings for individual operations
- ShowObjects: show innards of patched objects
- ShowLocalID: mostly for our internal debugging use
- ShowMoreInfo: default state of errors/warnings with more info
- ShowOperation: which operation the node/pin/link is on
- ShowSymbolSource: which document the node is coming from
- ShowTimings: show or hide timings alltogether
- StdDelayInMilliSeconds:
A few tweaks here and there and more viewers to come for more special datatypes over time...but the biggest part is hereby done. To test, download the latest preview and then please let us know what you think in the comments.
