iDome is an immersive projection system that creates a curved projection plane that fills the viewer’s field of view. It used a standard projector that projects a 360 degree image onto a curved mirror which reflects the projection onto a 3m fibreglass dome. The viewer stands driectly in front of the dome and has a rollerball which they use to navigate around the 360 degree video.
I found an article which suggests a way to make a homemade dome projection using a curved security mirror similar to the ones you see in shops as the reflection surface. If I can work out how to make a dome then I could possible use this technique to present my final project video this year.
