Encountering an Anamorphic Media Wall in Everyday School Life
“Please create a large, impressive display in the corridor!”
We received a request to fill a 7-meter-wide by 3-meter-high wall entirely with projected images. As the projected image grows larger, fine-tuned planning becomes crucial. Without careful consideration of brightness, contrast, screen size, and content, the resulting image quality can be severely disappointing.
What Are Edge Blending, Projection Mapping, Large-Format Screens, and Anamorphic Media Walls? Edge blending means seamlessly merging the output from three short-throw, 6,000-ANSI projectors into one continuous image. Projection mapping involves precisely aligning projected visuals onto defined spaces on the wall. A large-format screen refers to displays bigger than standard dimensions—here, a 7 by 2.2-meter setup. Anamorphic visuals use wide-angle techniques to create a three-dimensional illusion, adding depth and realism to the content.
A Media Wall Within Cheongju Technical High School
Although PaintPam has extensive experience with projection mapping and content creation, this marks the first time we’ve established such a dedicated media wall within a school.
A Screen Isn’t Naturally White
When people think of a screen, they often picture a white canvas, assuming high reflectivity is key. However, by carefully calibrating projector brightness, ambient lighting, and content, a silver or dark-silver screen paint finish can achieve richer contrast than a standard white surface.
Brightness Planning for Projection Mapping Is Crucial
Even the best screen paint won’t save a poorly planned projection mapping setup. You must balance equipment specs, budget, and screen size. Overreaching by filling the entire wall without careful calculation can lead to dim and blurry imagery.
Three Projectors and Edge Blending
Projectors must be positioned at the right distance from the opposite ceiling to achieve optimal brightness. The edge blending process involves splitting the video feed from a computer and merging three separate projector outputs into one unified image.
A Secure Housing for the Media Server
A locked enclosure safeguards the media server, preventing unauthorized changes or accidents. Marked with “CCTV in operation,” this setup could have been pre-planned more thoroughly, but it nonetheless ensures stability and security.
Enjoying the Completed Installation
We appreciate the positive feedback, especially for the waterfall scenes and the anamorphic 3D visuals. From seasonal imagery to water droplets and waterfalls, as well as anamorphic effects, a wide range of content loops continuously. We hope that students arriving at school and visitors to the center will start their day feeling uplifted and inspired by these immersive visuals.
The anamorphic media wall at Cheongju Technical High School’s AI Future Technology Education Center exemplifies how immersive visual experiences can redefine the educational environment. Through projection mapping, edge blending, improved contrast via screen paint, and carefully curated content, an ordinary wall transforms into an innovative digital learning space that inspires curiosity and engagement.
