technology and special effects
Sunday, February 6th, 2022 11:21 pmWhen watching things like the Olympics opening ceremonies (and also various music competition TV shows with a lot of special effects) in the last decade or more, I can't tell how much of it (if any) is computer generated graphics which are only visible on the TV screen, versus what is being shown and seen by the participants in person.
The giant LED screen on the field of the birds-nest stadium, I can understand. I still wonder how much more (or less) wondrous it looks in person. How clear is it? How real? Does it look pixelated up close? Is it real enough to seem like you're looking over a cliff?
But other parts like the "ice cube", I can't even figure out. Is it something physical or not? What do the people in the stadium see? It is a cube of LED screens that rises out of the floor? Is it a cube of glass that has images projected into/onto it? Or is it only a 2-D image on the floor which looks like 3-D from a certain angle? I need to know, in order to be able to appreciate it! Otherwise it seems like just any other special effect in a movie.

What does that mean? What is a virtual ice cube? Are the laser beams real or virtual too? If they are real, what are they pointed at, and how does it work? The next part calls it a projection display, but still, where is the video explaining how it is all done? Maybe I should be doing YouTube searches.
Even the Olympic rings leave me guessing. I guess they are made of some kind of translucent plastic or glass, and are hanging from wires? They are at least a real physical object, right?

A virtual ice cube emerges from the stadium floor, where 24 laser beams carve and engrave the names of the 24 previous Olympic Winter Games hosts before projecting the name of Beijing 2022.
