The video below show the culmination of many months of intensive development and experimentation with real-time 2D and 3D interactive techniques and camera/projection/environment alignment and calibration.
Each piece is designed to explore a different emotional and psychological relationship with both viewers and participants.

At the VBites vegan cafe we projected images of vegetables floating around the walls to emphasise the message of the restaurant. These vegetables could then be pushed around like balloons.
In the film below the cameras only detected stationary objects, if people walked by their image did not show up but if they stood still their image would appear, ghost like, on the screen
Out Of White
We also create audio reactive projections. In the example below the boxes appear to be coming out of the wall in 3D, reacting to the volume and pitch of the music.
The above example shows some plain white shutters. The beam of the projector is focused on the shutters and the details of the shutters, the window frame, the panels etc. are selected by drawing a box around them. Then the selected images are put into the boxes to create the final composition.
Accurately mapping projections to actual architectural details has traditionally been a complicated, time-consuming and expensive process, which would involve building a virtual 3-D architectural model, rendering sections of video in the studio in advance, carefully calibrating the positioning of projectors on-site before assembling the final show.
We can work in this way but we can also achieve the same results in a fraction of the time with our unique architectural video mapping system called PatchBox.
PatchBox, created by Alex May, is the only system in the world specifically designed to project hundreds of layers of moving video and still images onto any surface in real-time.
It is a flexible system that can act as a free-form multi-screen performance tool, or deliver complicated sequenced effects triggered via MIDI or OSC. It also features a ‘PaintBox’ mode, whereby colour can be literally ‘painted’ onto buildings using a graphics tablet. The results are powerful and immediate and can be combined with layers of moving video to create complex digital media compositions.
PatchBox is also able to correct the projected image depending on the surface we are projecting onto. So if a surface is curved or covered in architectural detail the final image will not be distorted.
The first image shows a video projected onto a curved wall, where the distortion can be clearly seen.
The second image shows the same video but corrected to compensate for the curvature of the wall.
All of this plus the ability to generate fully interactive video projection makes PatchBox a powerful tool in creating fully immersive video environments.
