Automatic Re-Calibration

Dear Tech-Blog readers,

it has been a while, not because of a lack of subjects, but rather because there was so much to choose from.

For those of you who might have wondered what our re-calibration approach is all about, here's a short video from last year's LDI that should help you understand this topic:

Fixed installations involving projections can now be set up in a way that allows for the creation of an exceptionally easy on-the-fly calibration environment, that can be operated even by non-specialists.

In the most basic sense, we are using a small NET Link device equipped with up to two analog fibre input boards, for the input of 16 fibre cables (single-core, diameter of 0.98mm²).

It has been specially designed for the automated re-calibrationof a projection setup, e.g. in a fixed installation where a projector or a screen has been moved.

Sometimes all it takes is gravity and time for a projector to move ever so slightly away from its original position at the moment of installation.

The tiny fibre cables would usually be installed inside the screen.

The cable ends act like pixels and won't be visible to an audience.

For a flat surface you would usually need a minimum of four pixel sized fiber cable points, for a curved screen usually a minumim of six points.


Kind regards,

Pandoras Box 5.7 Sneak Peek: Venue Sites

Hello dear Tech-Blog readers,

arguably one of the most impressive new Pandoras Box features that we presented at this year's Prolight+Sound are without doubt so called “Venue Sites”.

The Venue Sites feature is part of the upcoming Pandoras Box Manager 5.7 Software release.  The Venue Sites are used for visualising complete stage-, installation- and show-setups in realtime, using 3D models.

Media content can be pre-programmed per output and can then be routed to different 3d models this way.

What is special about Venue Sites is that instead of just offering a standard 3D mapping approach for pre-visualisation, one can now use a realtime compositing environment as a complete whole to simulate video projectors virtually, using a light projection rendering approach.

Media content and content compositing can be used completely independently from the visualised 3d scenes. 

The ability to seamlessly switch from one Venue Site to another, makes comparing different design scenarios very easy and helps to save valuable time and costs. 

Another important aspect of Venue Sites relates to being able to test and play around with the simulations of complex media installations. This way, one can for example train oneself to set up a spherical projection or a softedge projection without having to use real projectors in the process.

Finally here is a "visuals only" clip showing the Venue Sites. Please keep in mind that we are no designers, we just make the tools. We have no doubt that you will
be able to create much more beautiful setting yourselves:

Thank you for your interest!

Kind regards,

Real-Time Tracking ID-Tags

Hello dear Tech-Blog readers,

as some of you might have heard, we presented a really ingenious new product at this year's LDI in Las Vegas.

What's the product called? At the moment we are simply calling them ID Tags. These tags will make real-time tracking scenarios not only easier to set up, but also more reliable, more versatile, and more cost-effective.

 Interactive projections, camera automation, stage tracking, audio tracking and lighting control are just some of the areas in which the tags will be of great use for a variety of creative setups.

The important technical bit:

Each of the tags can be addressed with a unique ID, which opens up the possibility of up to 256 different unique IDs being tracked in real-time within a single setup. 

One individual tag has two LEDs onboard and can have between one to two additional infrared LEDs attached to it. 

Tracking people or objects this way is achieved using a purely optical transmission system, which means you can avoid a lot of potential problems that are sometimes linked to radio control based setups.

The coin sized ID Tags can be easily attached to set pieces, costumes or any other part of a tracking setup. 

You can fit a tag with a button cell battery with enough power to last over 10 hours.

 Alternatively, a micro USB port can be used for connecting additional power sources.

2D Tracking setups can be realised with as little as one camera, 3D XYZ tracking will require a minimum of 3 or more cameras.

Using the coolux Widget Designer Software for creating the actual control setup, users can choose between different modes, depending on each individual setting and lighting situation. 

Two types of cameras can be used for ID Tag tracking setups: USB cameras with 100 fps, and network-power-via-Ethernet cameras with up to 250fps.

If you need more specifics regarding the cameras, feel free to send us a mail and we'll try our best to steer you to the most suitable components.

Almost needless to say, coolux Pandoras Box software and hardware products are of course fully compatible with the new ID Tags and are the natural choice for project solutions that feature real-time media rendering up to 4K and beyond.

Here is some un-edited footage from our LDI booth (a proper clip will follow in the weeks to come), so that you can see what this is all about. Special Thanks go out to our friends at LOOP LIGHT for their support during LDI (in case you were wondering, an ID Tag was attached to the mini-copter):

Thanks for your interest!

Kind regards, your coolux team


Widget Designer Spyder Integration

Hello loyal Tech-Blog readers,

we recently integrated a Spyder X20 device node into our much beloved Widget Designer node system, including a Spyder Touch Panel, which can be compared to the Multi Touch Panel.

The Spyder Touch Panel can control the position and size of up to 16 of a Spyder's layers.

All data regarding pixel space and layer sizes can be entered into the dropdown lists in the form of pixel values.

Two commands for controlling the size and position of a Spyder Touch Panel layer have also been implemented.

Some of you might want to use the Christie I-Kit for creating an interactive control solution for the Spyder, which will also be possible with the upcoming Widget Designer PRO (and ULT) revision.

Using the Spyder Device Node, one  can also send all commands, whcih can be found in the Spyder documentation.

The node takes care of the network communication and the formatting of the commands so that they work with the Spyder network protocol.

You will be able to find the Spyder Device Node in the future under Nodes->Output->Devices 

Access to the The Spyder Panel can then be found  under Create->Panels

Thank you for your interest!

Kind regards,

your coolux team


Camera Head Tracking

Hello dear Tech Blog readers,

here is a short clip showing you the coolux Pandoras Box booth tracking demonstration at the IBC 2013.

A Vinten Radamec VRI Box is connected to the Pandoras Box realtime rendering system, which allows for 3D objects to be tracked in realtime via the movement of the camera head.

Pan, Tilt and Zoom data can all be read and processed in realtime to allow for augmented reality and/or virtual studio setups. More information on Radamec products can be found here:
