Shouldn't the torus and the latter sphere be partially transparent if they are build from motion blur ? They seems to become opaque again at some point and it feels strange to me.
- johanvts 3y agoIs light discrete or continuous?
- account42 3y agoYes.
- xeyownt 3y agoI guess it cannot become transparent because you cannot see through an infinitely fast moving / bouncing object, because necessarily the object would intercept any ray of light crossing its course. However the light emitted by the moving object should be lower than the static object. So as the distance increases, the object should become darker and darker.
- Rexxar 3y agoHere is a real life similar example: https://mitxela.com/projects/candle https://mitxela.com/projects/candle. It's clearly transparent (except in middle).
- vultour 3y agoYes but that one is not moving infinitely fast. If it kept accelerating it would eventually become opaque.
- willis936 3y agoIf the ball takes up 45 degrees in the torus then it would be 7/8 transparent when moving infinitely fast. It would be another 1/8 transparent when spinning the torus into a sphere. "Infinitely fast" being a stand-in for "sufficiently fast" and gated by the speed of light, of course.
- CyberDildonics 3y agoThere is no such thing as "moving infinitely fast", that's something the other person made up. What if light didn't fly straight and made loops and flowed like water and clustered up and stuck together? If you're going to make up nonsense, you're not talking about physical reality you're talking about cartoons or magic and fantasy. When something moves fast in photography it has motion blur and that spreads its coverage over a larger area. In this demo the motion blurred 'torus' and 'sphere' both get made artificially more opaque to make the animation work. You can see it happen.
- drewtato 3y agoIt's definitely blending between sphere and torus, and then torus and sphere. Otherwise it would keep getting fainter as time went on.
- pierrec 3y agoYes, the torusphere concept is physically impossible. Because the whole thing is a loop, the object doesn't even have any theoretical substance, it's all made of (artificially thickened) motion blur. Hence the title, motion blur all the way down.
