Week 11’s class had us go up to floor 5 of the University to see a demonstration of a HD LED video wall. Henry and Mike and Andrew all showed how the Led Screen’s work, demonstrating with a single LED panel and a small LED wall made up of about 200 square frames. each panel is made up of tiny LED lights that produce 4K quality work. The panels are made from industrial magnets, and they’re all linked to a single main battery that connects them together. You can have curved walls or a spherical wall by linking the batteries up in a certain way.

How the panels work

1. The camera speaks to the pc and the wall so when you move the camera the environment is rendered twice, once for lighting, the other for frustrum
2. The camera doesn’t see depth, it only detects the object in front of it. By blurring the environment you can fake depth.
3. The camera can focus on the person and blur background to create depth.
4. the Pcs have an industry grade graphics card that costs upwards of £15,000. The room itself costs £2 million
5. it costs £800 to hire the room, but its free for students, and you can use mocap suits as well.

The HD LED room can be used for all sorts of things. There are tiny dots on the roof to create a star map that tells the camera where everything is, and the x sign on the floor is where the virtual camera is. The room can also be used for VR Sculpting where you can put on VR headsets and fix the environment and set up cameras, and the director can see what’s happening on the big screen.
