This is CD on our 7’ X 17’ screen at work. We call this screen the “Power Wall”. There are two very large projectors behind the screen. They are blended in the middle to fill the whole screen.
We use it for presentations and simulation software. It also can be used in 3D mode. We wear goggles that track were we are looking. We use this for when we make entire factories virtually and then travel around in 3D looking at ways to make the plant work more efficient.
Its also great for movies and music videos.
