In order to get a better understanding on the techniques and i will be using in my project i looked into currently installations and came across Harrods interactive projection show which they did to promote the faberge egg collection for the easter season.
Window designer Stuart Henry conceived the idea of the egg, and his team at JUSTSO visualised an interactive projection show on a 1.5 metre 3D egg-shaped model. The model is based on real Faberge pendants, which are 1/100th of the size of the installation.
The installation is part of a five-window display with creative agency JUSTSO acting as project guardian. It also incorporates an interactive touch-screen element to showcase Faberge’s jewellery designs. The project represented specific technical challenges for the production company that designed the digital and company that supplied the projectors as the entire egg took up 16 high definition projectors to project highly detailed 360 angles of 3d egg model. Projector alignment was a challenge as the egg has no defining corners, but a seamless output was facilitated by high resolution 3D scanning technology.
Projection Artworks’ animation studio and in-house development team worked together to create dramatic interactive content that allows Harrods shoppers to explore the world of Faberge via a custom-designed touch screen. Shoppers choose their favourite Faberge design and watched a as a personalised 3D projection show unfolded before their eyes, inspired by their selection.
Due to the fact that projections generally work best in the dark a daylight visible projection was created using their DisplayMapper technology, which works by applying large amounts of light to relatively small areas. The Faberge egg is covered with an unprecedented 14,500 lumens/sq metre, around 200 times brighter than a typical outdoor building projection. This feature made the egg one of the brightest projection mapping show.
This project shared a lot of similarities with mine, it was done as a marketing campaign for the store’s products and it was created for a window display. So the challenges they had are the same as mine.
However, due to the fact that i have limited resources for m project in comparison my approach to overcoming these challenges are a little different. They approach the daylight problem by using 3d scanners and a large number of projectors to ensure that the virtual egg was visible in daytime.
Since i don’t have as many projectors i will be proposing an alternative method to achieve similar results. The shop window is smaller than that of Harrods and so the daylight is coming from one centred direction so the key thing to do is to limit how much sunlights gets through as much as possible whilst still having visible windows.
The way to do this is to add stick on tint films to the windows, these are not permanent and can be removed at anytime. A 35- 50% tint film should do the trick as it reduces the amount of light passing through but the windows are still clearly visible from the outside.
Once this is done you have a semi darkened window and 2 projectors but the projections will still need a little push to be as bright as they can be. So the next step is to paint on Goo screen paint onto the surface that will projected on. This will enhance the intensity of the images and the projection will be just as visible in the day time.
“Screen Goo products are specially formulated, color correct, video screen coatings in liquid form. They allow the user to transform any smooth paintable surface into a high performance projection screen. The affordability and versatility of Screen Goo has seen it used in myriad applications, from home theatre to large scale commercial installations.”
“Screen Goo’s performance reflects many years of research and development. It has the capacity to outperform most of the existing screen products in use today. Screen Goo is made from a proprietary combination of the highest grade coating components available. Premium acrylic resins, museum grade pigments and other optical “Goo-dies” are blended using custom designed, purpose-built mixing equipment.”
Here is a video that talks about how the Goo paint system Works
