02:05 - It helps placing the camera far away not only because it makes it harder to notice the difference in the object size, but also it actually minimizes this difference, because the increased distance of light path going around the mirrors becomes a smaller percentage of the total distance from the camera to the object.

@Speeder84XL

Best thing, it's not affected by picture angle either. It's just the difference in distance as percentage of total distance that matters. So a camera can be put far away, then use a narrow angle lens in to give the appearance of being close, while still having the same effect as being far away.

@Lucas-nf1uq

I thought that the difference in size was because the line of sight coming from our eyes is never parallel. If the observer is further, the line of sight becomes closer to parallel and the difference in size is smaller. I mean, if you have a beam of light that's exactly parallel, the distance wouldn't matter, it would have the same size regardless of the distance. Does it make sense?

@Speeder84XL

@@Lucas-nf1uq No, it just has to do with the angles the light is coming into an eye or a camera lens. Things will look "smaller" if they are far away - regardless if you look with just one eye. Same thing for a camera. But if you campare 2 similar objects - one that's 2 m away and one that's just 1 meter away, the difference in "apparent size" will be quite big - but not so much if one is 19 m away and one 20 m away - despite the distance between the objects being 1 m in both cases. Even if you look thru a mirror reflecting objects behind you, not much will change as all relative angles are preserved even for reflected light. Same applies, even if the light bounces several times - the relative angles will not change as long as the mirrors are flat. If all relative angles are preserved, there will be no difference if light is coming from far away or if it takes a detour bouncing between mirrors. It's the length of the lights path that counts for how far away objects appear to be - and because of that, the longer light path will cause objects behind this mirror array to appear further away than they really are and thus look smaller. But the detour taken by the light is the same regardless of the distance to the fist mirror (that will be equivalent to the distance between the 2 objects in my fist example) - so if standing far away, the percentage of that "error" will go down. Even with a camera far away that used a telephoto lens that "error" will shrink with distance, because such a lens only makes the camera capture incoming light in a much narrower angle range (and thus can get much more detail within that range), but the relative angles between objects still doesn't change. That way, it's also possible to film with great detail and high resolution, while still make the error pretty much neglectable. The line of sight not being parallell affects our perception of depth (especially at short distances), since each eye will look at objects from a slightly different angle - just like having 2 cameras placed at a slight distance from each other. Our brain then interpret that as a single image with depth perception). But that doesn't matter very much here, since each eye is affected the same way. But that angle difference on the other hand, introduces an error at the edges of the mirror. That will also go down by distance.

@@Speeder84XL , thanks a lot for your patience. I was not referring about one or two eyes. I was just assuming that the apparent size is the angle we see an object, and the distance doesn't matter. Lets assume the object is 2 m tall. If it is 1 m away it will cover 90° of your vision (45° up and 45° down). If the same object is 2 m away it will cover 53,1° of your vision. If you double the distance the apparent size doesn't exactly divede by 2. If the distance is big I think the approximation is valid. The point I am trying to make is that our sigh of view is never parallel and that mirrors set works only for a parallel beam of light. Therefore there will always be a difference in the apparent size if we compare the object behind that "invisibility cloak". The difference in the apartment size will be smaller for larger distances, but the reason for that is the angle, not the "distance ratio".

@Lucas-nf1uq

11 ай бұрын

@@Speeder84XL, I forgot to mention... In the video with the camera fixed at the same distance from the mirrors set... If we put an arm behind the mirrors, the arm will look smaller then it should. Lets say its thickness is the half. If we put a chopsticks behind the mirrors the difference will be smaller, may be just 0.75. I am just guessing numbers. But the idea is that for a smaller object the difference will be smaller because the angle is smaller too. But the distance continue to be the same. I couldn't explain very well, I hope you understand what I mean. I understood your point and it makes sense, but I think we should consider the angle. Thanks one more time :)

The video game "Perfect Dark" for the Nintendo 64 has an item called Cloaking Device, which allows the user to be almost invisible. It actually seems quite realistic, because it isn't perfect - it is possible to see very faint colour and shape distortions if you look directly at the user, and it deactivates for a few seconds whenever the user fires a weapon or performs some other dramatic action.

Really cool effect

You could use a lens/curved mirror to compensate the distancing effect, right?

@chitlitlah

11 ай бұрын

Not perfectly. Even if you managed to turn the whole thing into a reflecting telescope, it's going to magnify everything by the same amount. That's a problem because things right behind the _cloak_ will normally look a bit small and need some magnification, while distant background objects will already look pretty normal, so magnification will make them look large. You couldn't tune it so objects look quite right no matter how far behind they are.

Crazy. Love it.

If you had a directional display that's also a directional light sensor (so they know/control the direction and intensity of the light on each pixel), then you could make the light virtually pass through you without any external mirrors like this. So like a surface that is a holographic display and a lightfield camera at the same time. I think there's already tanks that do something like this in IR.

This is "amusement park" level invisibility.

Tried this at home with small mirrors. Had to use a shelf at eye level and stand way back. It worked, but the "smaller than it should be effect" is strong. You must have worked very hard to get it to work so well. It's a lot of fun, though.
