VPT 6 video tutorials

VPT 6 available: A projection powerpack

With almost 5000 downloads of VPT 5.1, I am happy to announce that the next version of Video Projection Tools, VPT 6 is now available.

VPT is a powerful and flexible video projection tool that does much more than just mapping.

What´s new in VPT 6.0
A completely new graphical interface making it even simpler to position, scale and distort the layers.
32 layers (previously 16)
mesh distortion with variable-sized control grid.
a completely rewritten cuelist making it even simpler to create transitions and to build complex sequences. You can now also send osc formatted commands directly from the cuelist.
crop-scaling of sources.
increased syphon support with two syphon (crop-scalable) inputs as well as syphon output support (mac only)
a DMX module has been added, with support for Enttecs usbdmx pro interface, enabling both control of VPT from DMX light consoles, or the possibillity to control dmx devices from VPT.

VPT still supports mac and windows, and it is still free. However, I have added the option for contributions through paypal:

VPT 6 is made possible through the support of IMAL in Brussels and Atelier Nord in Oslo.

IMAL offered me a one month residency in april to give a VPT workshop and to do an exhibition.

Atelier Nord has supported me twice this year: First they hosted a workshop as part of Oslo Lux in January which ended up in a VPT 5.1 release, and in june they gave me a week residency to write documentation for VPT 5.5 which instead turned into intense development of VPT 6.

So hosting workshops and inviting me to residencies is another way of supporting my work.

VPT 5.5 preview

(update: VPT 5.5 turned into VPT 6 before it got released, and can be expected very soon)

I am busy finishing the upcoming release of VPT 5.5, and wanted to share a few of the new features.

One major addition is the possibillity to perform mesh distortion to each layer, giving you even more flexibility over the projected output.

The control interface gives you control over each point in the mesh.

Syphon is becoming an important tool for sharing image data between applications on Mac osX, supporting more and more applications (there is now a more or less working Processing implementation as well).

VPT already impemented syphon-in capabilities with version 5, but with version 5.5 there is more:

You can record the output from VPT using the Syphon Recorder App.

You can use different parts of the incoming Syphon image data in different layers: Using your favourite syphon-enabled application you can tile your output so that VPT split up the single syphon source into multiple sources.

For instance, if your syphon-app sends out something like this:

VPT can either use the whole image or split it up into four individual layers:

There are plenty of other improvements, which will be covered when it is released.

For VPT 5.5 I finally get the possibillity to make proper video tutorials, as Atelier Nord has generously offered me a one week residency to do this.

Expected release date: mid-June.

As always, free (with the possibility to donate).

btw, about 3500 people have downloaded VPT 5.1

VPT 5.1 available

After nearly 2500 downloads of the first version of Video Proejction Tools VPT 5 released in december 2010, I am happy to announce the new version 5.1, partly based on feedback from workshops and the VPT forum.

The release focuses on all the possibilities to expand and customize VPT to be the right tool for your particular project.

This includes a vastly improved controller section, making it possible to control almost every feature of VPT from another application (like maxmsp, processing and PD), computer, sensors through the arduino microcontroller, midicontroller as well as built in lfo controllers for automating control and software sliders and buttons. This comes on top of the already existing built-in preset and cuelist system for playback. Through OSC, VPT parameters can relatively easy be controlled by gestures, using camera or kinect tracking.
You can easily set up VPT to control simple projector shutters by controlling servomotors using the arduino module.

Templates are provided with the download for exploring OSC on maxmsp and Processing, PD will follow later. Arduino templates for input/output as well as a servo example is also included with the download.

VPT can be used with multiple projectors using Matrox Triplehead2go, and the latest version also includes support for multichannel sound: The movie sources can be individually routed to up to eight channels, depending on your sound card. Using the provided maxmsp template it is possible to process the sound further.

VPT 5.1 includes a new possibillity of processing the sources using the FX bus. The FX bus consists of eight FX chains, modules which contains shader based effects. New FX chain modules can easily be made using the provided maxmsp/jitter template, and can be dragndropped onto the existing FX chain to replace it, making it easy to customize the effects to your particular need.

Three new sources have been added to VPT: A solid (if you just want a colour in a layer), a noise texture generator and a text module which can either use text from file, osc or typed text. A maxmsp/jitter template is also provided if you want to create your own source.

VPT is a free multipurpose realtime projection sofware tool for Mac and Windows developed by HC Gilje. Among other things it can be used for projecting video on complex forms, adapt a projection to a particular space/surface, combine recorded and live footage, or for multiscreen HD playback.

Fuglane-behind the scenes

I have uploaded some images from the process of constructing the landscape for the Fuglane scenography, you can see it here as a slideshow.


I started off with a plastelina model (which I don´t feel like sharing with the world), and then continued with a google sketchup 3D model.  I  then got the model milled in styrofoam to use as the presentation model of the scenography. Later the 3d model was converted into technical drawings used by the skilled carpenters at the theatre to build a full scale version (about 10mx7m, the highest top about 1.6m). It was then covered by a material to make it more suitable as a projection surface.

I used a total of 4 projectors, two from above, one frontal, and one for the back wall. I used two macminis with matrox dualhead- to-go splitters and a customised version of my projection software VPT (not unlike the upcoming release).
Everything was controlled from the lighting console of the theatre, using an enttec dmx usb pro interface combined with Olaf Matthes excellent max externals.

VPT workshops

Well, it´s no secret that a shiny new version of VPT is just around the corner.

The first people who get to try this version are the participants of the upcoming VPT workshop in Bergen, hosted by BEK.

The workshop takes place December 6th-9th.
Sign-up information.

As part of the Lux festival in Oslo I will give a workshop hosted by Atelier Nord January 22nd-23rd 2011.
Sign-up information.

In april 2011 IMAL in Brussels will host another workshop. Sign-up information will come later.

They´re back

For the occasion of Festpillene i Bergen 2010, a flock of Wind-up Birds has taken over the mountain side of the Fløien mountain. More specifically along the windy, steep path through the spring-green forest called Fløiensvingene. They will probably stay a few weeks. This has created a lot of buzz among the people using the path, so I will try to spend as much time as possible there to listen to audience reactions.

They might sound similar to previous generations, but there has been a few changes under the hood: The wood blocks have this time been milled instead of glued, making them more robust. Thanks to Ivar Bergseth and his CNC mill!

I use a new set of xbee modules, the xbee 2.4 pro digimesh modules. This gives a more stable network and is much easier to work with than the previous firmware.

I made new more practical circuitboards, which I got manufactured at BatchPCB, making the job of assembling the woody boards much easier. This was my first attempt at working with Eagle PCB circuit design software, but I leaned heavily on Roar Sletteland´s previous PCB layout for the first generation.
