Ring Quader – Hall

One work as a triptych, 18 metres wide, in an industrial hall

VisualisationIndustryFree spatial study

Visualisation of a fictional space – not a realised project.

A hall thirty metres long with dark-painted brick walls and two rows of concrete columns. On the end wall, “Pfeiler” from the Ring Quader series runs as a triptych across three projections.

A wide band is cut from the work video and divided between three projectors hanging from cross trusses beneath the roof. The image is 18 metres wide and begins at a height of 1.50 metres, so that it remains visible even behind groups of visitors.

Visitors enter the hall through the gate. Between the columns, the coloured light of the work falls on the floor and the brickwork; the columns structure the space and give the image depth.

Technical details

What it takes to build this space: dimensions, equipment, brightness.

Three Panasonic PT-MZ882 projectors with ET-ELW22 lenses (short-throw zoom), 8,200 lumens each, hang from cross trusses. Each partial image measures 6.00 × 3.38 m with its bottom edge at 1.50 m; the throw distance is 4.80 m (throw ratio 0.80:1, lens shift -45% vertical). Calculated luminance on the wall: approx. 129 cd/m². Alternatives, price range and all dimensions per device are listed in the equipment list; floor plan, section and axonometric view show the projection cones.

Projection

How the images are created: equipment, image size, distance and mounting.

3 × Projector

6 m × 3.38 m per image

Bottom edge: 1.5 m
Distance: 4.8 m
Throw ratio: 0.8 : 1
Lens shift: -45 % vertical
Mounting: on the truss

All partial images come from one video – they are played back in sync.

Brightness

Whether the image will be bright enough: luminance achieved against the target value. The line in the bar marks the target value.

Glossary

Throw ratio: Distance divided by image width. At 0.8 : 1, the projector for an image 6 m wide stands 4.8 m away.
Lens shift: Shifts the image within the lens without tilting the projector – so it stays rectangular.
Luminous flux: How much light the projector emits, in lumens.
Luminance: How bright the image surface appears to the eye, in candelas per square metre. In a dark room, about 60 is enough.
Bottom edge: The height of the bottom edge of the image above the floor.
Synchronised playback: Several projectors show parts of the same video; a media server keeps them in frame-accurate sync.
