PROJECTION MAPPING
Projection Mapping
Overview
I wanted to create an installation for a live music performance. I decided to create a hanging cardboard surface on which I could project imagery. Each element of the structure would be an individual shape in three dimensions and I would stagger the depths of each one to create a unique way to display projected content, that in itself would look more dynamic because of the nature of depth of field.
Development
Inspired by 3d origami paper folding, I set about making unique and organic geometric polygons. I then made a small scale model to see how the structure would hang and to easily envisage the depth of the piece when ultimately scaled up. Using large sheets of card, I then sketched and cut the shapes, turning and folding them into a 3d surface to the orientation and dimensions of the model.
Construction
Using a projector and a test image I live traced the cluster of shapes and with Adobe After Effects I developed my own projection mapped art that could be spread across each one. Every layer could provide different content for each shape, or the entire cluster could be used as one overall mask with which to project a single video or image. Allowing for the depth of field created by the angles and distance in the 3D structures, I had to make sure the artwork would project precisely onto the individual structure. I carefully measured the distance and angle of how each component was hung in the test environment. Fire safety regulations meant that the practical application of hanging each element needed to be done with approved stage wire and have the cardboard pieces sprayed with flame retardant coating before the final installation.
Installation
On the day of the live event, I installed the structures into the performance space (above the stage) in the venue, using the test screen to manually align each component. I instructed a lighting engineer as to when and how to project the content I had provided.
Conclusion
As the technology involved the practice develops I would love to further explore projection mapping in my studies.
