Helo evvvveryone,
(and your friends who don't use vvvv yet)

Here's to announce that we're continuing our free introductory workshops, to give you a taste of what it feels like to work with the all new vvvv.

What the vvvv?

vvvv is a visual programming environment that allows you to realize ideas 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!

To give you an idea of the areas vvvv can be helpful in, here is a list of buzz words vvvv is often associated with:

What happens in the workshop

In these 2 hour courses we'll be using vvvv (version gamma) to:

• give you an overview of vvvv's possibilities
• guide you step-by-step through creating your first little programs
• mention things like Kinect, Midi, OSC, TUIO, UDP, Rs232, Leap, Vive, Rift, DMX, Art-Net, Arduino, Lasers, Motors,...
• leave you with an idea of what next steps you can take to divvvve deeper

Who is this for?

• the curious, who are interested in adding a new tool to their toolbox
• the lazy ones who want to get their things done more efficiently
• the ones afraid of coding, who want to try visual programming instead
• those familliar with vvvv beta who want to move to vvvv gamma

When?

Choose one:

• October 22, 6-8pm (followed by a vvvv meetup)
• November 14, 6-8pm (followed by a patching circle)
• November 26, 6-8pm (followed by a vvvv meetup)
• December 12, 6-8pm (followed by a patching circle)

Hope to see you soon!

When Tue, Sep 24th 2019 - 20:00 until Tue, Sep 24th 2019 - 20:00
Where Wipper13 Brüll & Kraus, Wipperstrasse 13, Berlin, Germany

It is the 4th tuesday of the month again. Tomorrow!

That's why we're going to meet up and share some vvvv stories and drinks at the fine Brüll & Kraus in Rixdorf, Neukölln.

We'd love to hear from you: If you have something to show or talk about, please do so! Bring your projects, demos, works-in-progress and show us what you're patching with!

Also expect a little live-demo of the new export feature of vvvv gamma and another nifty new little feature...

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

• September 12 and 24: Free introductions to vvvv gamma

Jobs

Aas 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 August. Anything to add? Please do so in the comments!

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.

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
