The point being made in context here is valid, about depth perception and immersion, but picking nits, to me this guess doesn’t feel right at all in terms of describing the viewing experience. The main viewing area is center front, opposite from the “good” seats in the middle, and there’s nothing within 20m of it, or even 50m I’d speculate. The good seats are probably 80m away, and most of the rest are further. No matter where you sit, the undistorted view is across from you, you tend to look away from the very closest part of the screen. So people on the sides might be close to their side of the screen, but are primarily looking at the stuff across from them and in the center front. The parts that are within 20m are designed to be periphery no matter where you are. Except for the floor, where I might have been within 20m, but I was looking at the band 20m away, and only looking at the screen for stuff much further.
- adrianhon 2y agoAuthor here: I was being overly conservative with the 20m, yes. Assuming the cutaway view in the post is to scale (it's from an architectural firm), it shows the inner screen dome is quite a lot smaller than the exterior structure – perhaps 70-80m tall; so 40-50m might be more accurate.
- dahart 2y agoOh your statement might be correct, that the average distance to closest point on the screen probably is about 20m, and guaranteed to be less than 1 radius (more like 0.5 radius perhaps.) If the cutaway is accurate, and it probably is, the interior is smaller than it feels like. So I may be underestimating how far away 20m is. I felt further than 20m away standing on the floor, but I probably wasn’t. But, what I’m really saying, is that the direction to the closest point and the average viewing direction are only similar for the best center seats, and they’re as much as orthogonal for the bad seats, the further away from the center you sit. The average view is probably greater than 1 radius, you’re generally looking across the center of the sphere. I am picking a bit, but this is also an important part of why there are no terrible seats, the viewing experience is more uniform because the view across does not correlate with your distance from the nearest point. I think this relates to why it feels immersive and works.
- adrianhon 2y agoThat's fair – the spherical view does so much!
