Using the OSCQuery Helper tool with Processing

In our introduction tutorial for working with Processing and VDMX we examined how to manually configure sending OSC messages from VDMX interface items to control properties of a Processing sketch running in the background. For this follow up lesson we will look at how the OSCQuery Helper tool can be used to publish the OSC address space for a sketch so that they can be remotely accessed by other software like VDMX or the OSCQuery Browser tool.

Using the OSCQuery Helper and MIDI OSCQuery Helper tools with Max

One of the most powerful tools for working with MIDI and OSC control data is Max, which is widely known for its easy to use interface for “patching” and working with data streams. While Max does not yet support OSCQuery natively, it is a great example of how the free OSCQuery Helper and MIDI OSCQuery Helper tools can be used to publish OSC and MIDI parameters from Max patches so that they can be remotely accessed by other software like VDMX and the OSCQuery Browser.

In this set of tutorials we’ll look at the process for adding basic MIDI and OSC inputs in a simple Max patch and then creating a JSON file that describes the routings. Once those are prepared we can see how to access these parameters using other software in the OSCQuery ecosystem.

The OSCQuery Client Plugin

The OSCQuery protocol makes it easy for software that supports OSC to access each others parameters for remote control, without a lengthy setup process. Within VDMX there are a few ways to take advantage of this and in this tutorial we will focus on using the OSCQuery Client plugin which can be used to browse the address space of a server and add UI controls that are automatically configured to send to it.

Using OSCQuery In The Control Surface Plugin

The Control Surface is one of the most widely versatile plugins in VDMX, making it possible to create sets of custom interface elements that can be used to control nearly any aspect of your workspace or send MIDI / OSC / DMX to other systems. The Control Surface plugin also has the ability to publish its list of parameters over a local area network using the OSCQuery protocol so that other software can remotely browse and control almost any aspect of your VDMX project.

In this video tutorial we'll be looking at the basics of using OSCQuery protocol from within the Control Surface, and three ways that those parameters can be accessed from software running on other devices: using our free OSCQuery Browser utility, another copy of VDMX and a web browser running on an iPhone.

Animating Properties of GLSL Shaders in VDMX

When writing GLSL shaders that run as generators or are used as image filters, one of the most fun parts of the process is playing with different control functions to animate all of the various variables that you've created in the composition. Using the ISF specification, GLSL shaders can publish their uniform variables so that host applications can provide user interface controls that can be connected to MIDI, OSC, DMX or other data-sources for automation.

In this tutorial we will look at adapting an existing GLSL shader into ISF, publishing some of its variables as uniforms, and loading the composition into VDMX where we will animate its properties using a variety of different plugins and MIDI input.

Blair Neal's Survey of Alternative Displays

For anyone currently working in the field of live visuals, one of the most exciting areas of bleeding edge technologies is on the side of displays – the place where people look at to see the amazing imagery coming out of our computers. There are a lot of new – and ancient – techniques to learn about and along with that a lot of new information to take in – all of which our good friend Blair Neal covers in his recently updated blog post “Survey of Alternative Displays

Loops – Performance, Production, and Progression

The heart of almost every VJ / Visualist performance is the loop. There are lots of techniques and training for the production of loops, but there are some common approaches and methodology of creating a “pack” that are explored in this guest tutorial by Colin Evoy Sebestyen. To demonstrate these ideas Colin breaks down a project he created with musician Nonagon for a performance series at The Tech Museum of Innovation in San Jose.

How to create a retro Halloween visual style in VDMX

Creating the right look for Halloween and other spooky themed events is one of those tricks that every visual artists needs to have in their go to bag of tricks. There are lots of different techniques that can be used and in this guest tutorial we are joined once again by Colin Evoy Sebestyen for a demonstration of how to use a combination of LUT based FX, real-time video generators and logo images to create a retro horror film graphic scene in VDMX. In particular this look is inspired by intro sequences like the one from The Gate and more recently Stranger Things.

Mixing, Adjusting and Generating Complementary Color Data-Sources in VDMX

While Quartz Composer is mainly used for creating interactive video sources and FX, one of of the other powerful ways it can be used in VDMX is to create your own custom plugins that can generate values or manipulate data-sources that can be used to drive other parameters in your setup. Another great thing about this feature is that once these compositions are created they can be shared and easily installed on different computers so that other people can take advantage of the new functionality.

For this tutorial we'll be looking at three very simple Quartz Composer compositions can be used within VDMX for manipulating color data-sources in particular.

How to do a NYE Countdown

One of the biggest nights for live visual performers is New Years Eve and in particular there is responsibility in particular that can be unexpectedly tricky to get right. That is handling the countdown to midnight. Often it can mean coordinating with other performers or workers at the venue. Depending on what is required of you during the show there are a few different approaches you may want to take when setting up your projects. It also helps to have an idea in advance of what your options are for running a visual countdown.
