Glad to see another video/post. Very informative. Thank you.
It's a new project? An update?
No, it's old, but I've made some updates, and a lot of people who own AR Sandboxes don't know the total of all features in there, so I figured I needed a detailed overview.
Wow they just literally proved the earth is flat !! Take their flight path and put it on a flat earth map haha
You mean like this: imgur.com/a/mYImUUU How exactly does that prove that Earth is flat?
Weird how none of the circumpolar flights ever go directly across Antarctica from Buenos Aires to Perth or Cape Town to Auckland.
It's not weird at all if you think about it for, like, ten seconds. How would a circumpolar flight get from the North Pole to Perth or Auckland, or vice versa?

Thanks, it is really fun for how simple it is. And yes, it does run on a potato. When I was filming this, I was running on a good development PC, but my daughter was playing from a 10-year old PC with a GeForce 680 (not a typo). Doesn't get much more potato than that. :D
It is totally flat. The bottom cutoff of the mountain and land in the image is due to Atmospheric Perspective and due to the geometric principles of perspective. Light rays start bending down as humidity (density in the air) increases closer to the surface of the earth. Since light rays are reflected off objects in the distance, the further the objects are, the more bending of reflected rays happen until the whole object is no longer visible. The objects start disappearing from the bottom. As the object gets further away, it gives the illusion that it is sinking in the distant horizon. Like the ships for example. The further they get away the more the seem to disappear from the bottom up. Not because of any curvature, but because of the Atmospheric effect on the light. As an example of geometric perspective, try this experiment: On a flat surface like a airport runway or long parking lot, place a video camera on the ground level and ask a person to walk away from the camera towards the other end of the field. As person starts walking away from the camera the person appears as as if he is sinking in the ground and eventually disappears from the camera view. Even though he is walking on a completely flat surface. Here is an experiment on how light bends when the medium changes density (like the atmosphere): ua-cam.com/video/sft3QYZjNCU/v-deo.html
How does the fact that light rays bend downwards cut off the bottoms of far-away objects?
@@okreylos the bottom (lower side) of the object disappears first since it is closer to a denser medium. That is why the ship starts disappearing from the bottom up because of the higher humidity closer to the water surface. The rays from the bottom start bending and don’t reach your eyes.

The original researcher used normal camera converted to see the infrared spectrum.... infrared let’s you see through more of the atmosphere as it captures the spectrum of light not visible to human eyes. Is doesn’t stop or negate atmospheric refraction (which you did not consider at all ???), with infrared you can see through haze... refraction is the bending of light that happens because of the atmosphere. Light bends down as the density of the medium increases. ua-cam.com/video/c6HVWe9tMFA/v-deo.html
How does light bending downwards make the bottom of a far-away mountain disappear?
If you’re on a curved planet, that laser light refraction would follow the curve due to refraction and therefore not be going straight. As in, not level horizontal
However we are not in a 'container' there are no side walls for the atoms to bounce back and forth from?
You can see the same simulation without side walls in this video: ua-cam.com/video/TyVx3UnZbVU/v-deo.html But anyway, the existence of side walls in this one is irrelevant. Imagine that there are more, identical, column of gas on the other sides of both walls, and then imagine removing the walls. Gas now bounces against gas instead of against walls. Nothing meaningful changes. The point is that the gas does not escape *out of the top of the container.*

Hey! Thanks so much for sharing your work with us, I am trying to build a small AR sandbox for my autistic daughter. I followed the guide you posted for installing AR Sandbox on a Linux box, and everything went exactly as you said in the instructions on the forum post. I also have all the shortcuts on the desktop, but when I try to actually run the AR Sandbox I just get a white screen. Are there any other more detailed instructions published that would help me configure this software? I have the Kinect and projector both working great, I feel that I'm just missing a small piece of this to get it all working. Any insight is much appreciated!
OMG. I have trying to find a simulation showing this. Every single info source I checked insist that the pilot need to make constant direction changes but my logic told me that wasn't right. I was no wrong. People never try to think for themselves, they just believe what the other people tell.
It's a bit more complicated than that. Geometrically, a great circle path is a straight line, meaning you don't have to turn to stay on it. But: how do pilots determine whether they are flying in a straight line or not? Planes always yaw left/right without the pilot's interaction, and pilots continuously need to counteract those random course changes. They do that by using their heading indicators, which are basically compasses and show the angle towards north. The problem is that, when flying on a great circle route that is not the equator or a meridian, your compass direction will change continuously. So when they want to fly along a great circle route, pilots have to continuously change course, as in their heading angle relative to north, to stay on a straight line. To be clear, by "change course" I don't mean "turn." I mean that as they are flying straight, their compass direction changes, and they need to be aware in which direction they have to fly at any point in order to make the correct corrections. That's why great circle routes are hard to plan and hard to follow without on-board computers or GPS.
Computer simulation is not proof, what's so crazy is all the evidence and proof we have the world is a sphere. If you want to deny facts it's a free country to be stupid. Flat earthers are like believing in a goD/religion, no proof of existence/make believe. (Bible ain't proof, anyone can write a book)
"Computer simulation is not proof" That's flat Earther talk!

Would you please explain what you mean by that, because I' have no idea what you are even talking about.
There is a new video out by Professor Dave debating a flat-eather. At 12:12 you can see the picture of a mountain in the video and some math. Could you take a look into that?
That's about right, when ignoring atmospheric refraction. With standard refraction taken into account, the hidden height drops to 8,908 feet. Which leaves 3,700 feet of visible mountain. Without knowing that area or the conditions under which the photo was taken in detail, the picture looks consistent with the globe. Rule of thumb: When someone claims a certain observation would be impossible on a globe Earth, that claim ends up wrong every time it's checked.
@@okreylos How does standard refraction factor into that? I'm not too familiar with optical physics. Does that mean how light is refracted at the horizon or over water? So there is nothing to see there that is exactly the amount of mountain you would expect to see if the earth was a globe did I get that right?
Under normal conditions, the atmosphere is optically denser at lower altitudes than at higher altitudes. This causes light travelling through the atmosphere to refract towards the ground. In short and in general, light above Earth's surface doesn't travel in straight lines, but in slightly downward-curved arcs. This curvature cancels out some of Earth's geometric curvature, virtually lifting far-away objects above their actual geometric positions, and making it possible to see farther than it were possible if Earth had no atmosphere. Diagram: imgur.com/gallery/refraction-PBCvr3T
@@okreylos I knew that there light travels differently and some phenomena are explained by it. But thanks for the explanation. I will take a look at it.

that is not circumnavigation
Why not? And what even is your point?
@@okreylos Circumnavigation requires following 1 longitudinal line without deviation
@@heavymetalnewsdesk That is a wrong and useless definition of "circumnavigation." Where did you hear that? The *actual* definition of polar circumnavigation by the Fédération Aéronautique Internationale is: 1. The course needs to be at least 21,000 miles (34,000 kilometres). 2. The flight must have been made to a control point north of 75 degrees north latitude and a control point south of 75 degrees south latitude. 3. The crossing of the equator from north to south must be separated from the crossing of the equator from south to north by 90 to 180 degrees of longitude. 4. The flight must be completed within 365 days in the same airplane. This flight satisfied all requirements.
@@okreylos because you can't prove that you crossed Antarctica unless you follow one longitudinal line that's why
@@heavymetalnewsdesk That's why your definition is useless. Longitudinal lines *end* at the poles. You cannot possibly cross Antarctica by following only one of them. Maybe you meant "following one great circle without deviation?" But even that is a useless definition. Anyway, check 1:50 in the video. The flight follows one line of latitude, without deviation, into Antarctica to the South Pole, and then another line of latitude, without deviation, from the South Pole out of Antarctica. Did it not cross Antarctica in the process?
Map it on a FE map and you’ll see they went south and came back north.
Neat idea! Here you go: imgur.com/a/mYImUUU Now would you please explain how, after flying due south from Mauritius (D) *to* the South Pole (E), they arrived in Punta Arenas, Chile (G), after flying due north *from* the South Pole (F)?

What about the solar wind "kidnapping" the outmost gas molecules by accelerating them beyond escape velocity?
earth-planets-space.springeropen.com/articles/10.1186/s40623-019-1048-0
The idea of "sucking something away" presupposes the existence of static gas pressure since a "suction force" does not exist in reality, only the force of the surrounding static gas exercised by its pressure differential. Deep space cannot suck away atmosphere, but atmosphere could diffuse into space if, for some reason, planetary gravity suddenly ceased to drag gases to the gravitational center of a planet.
Is this English ?
The earth is round. Get over it
You're confusing people with these models, use real photo's. Also, there are many proofs it's flat. The globe makes no sense. There are many examples, one is you can see too far and why are skyscrapers straight up. They should be tilted when veiwing from a distance or an airplane. When you fly you're flying on a level, you should be tolting down to maintain altitude. Lots of pilots have come out and the flights only match the flat earth map versu the globe. Can you debumk these ??
"Why are skyscrapers straight up?" Let's focus on this. Would you please explain that to me? You are at least the tenth person who has brought up this issue, and not a single one who came before you has ever elaborated on it. They must all have been very confused. Since you are a smart one, you shouldn't have a problem answering my simple question. You ready? Here it comes: Imagine, purely for the sake of discussion, that you are standing on a globe of radius 3,959 miles. Now imagine you are looking at a really tall skyscraper 50 miles away. By how much should that skyscraper be "tilted?"
@@okreylos Enough to see by eye. Don't need to give you a figure because they aren't tilted. Why can you navigate on a flat earth map and not a globe. They don't match. Also on your question about being 50 miles away, you might not see the buiding if only 400-500 ft tall at ground level. We're about 8 inches square permile. So 50 miles away you need to be high up. You belive this than. not possible with your model ua-cam.com/video/cA7xUmHIChg/v-deo.html
"Enough to see by eye. Don't need to give you a figure because they aren't tilted." That simply won't do. If you don't know, how can you be sure that it's enough to see? What if it's, say, less than 5°? Would you be able to detect if a skyscraper were leaning away from you by 5°? Also, "I don't have to because they aren't" is circular reasoning at its finest. Let's do an over/under. At 50 miles distance, on a globe of radius 3,959 miles, would a skyscraper lean away from you by more than 5°, or by less than 5°?
@@okreylos The globe is the same as a ball, right ? If the earth is curced like you state when you place a plumb-bob from the top of the 50 story building at each corner the bottom floor corner will be a different location. Cannot line up with your glode. Won't be square. When you're looking in any direction at a distance they will lean away from the viewer. A carpenter, autobody man or artist all have good prespective and can see when something is off slightly. With the specs you provide you should see a tilt especially from an airplane looking down from a distance. Should be very noticeable at distance or even close as well. The earth is still and the only moving object a plane can land on is an aircraft carrier. Your questions don't amount to anything, use your eyes. You can simply see too far. I've travel on the water and some days could see over 75 miles to shore from 14-16 ft up. Your own radius figures say no you can't. How does that work ?
I see a picture forming. You, like all other flat Earth proponents who have been able to actually communicate their belief to me, seem to suffer from an inability to understand scale, specifically the scale of Earth. You claim that Earth must be flat because far-away skyscrapers would be leaning away from you otherwise. You claim that Earth must be flat because tall buildings would be out of plumb otherwise. Here is the secret: far-away skyscrapers *are* leaning away from you. Tall buildings *are* out of plumb. The issue is that your intuition on *how much* they are so is completely disconnected from reality. Earth is really big. Let's talk tall buildings for a moment. Take the Empire State Building. It is 381 meters tall, and 57 meters wide. If Earth were a globe as they say, the building would be 0.0005° out of plumb, or 1/2000th of a degree. *Do you honestly think you would be able to detect that with a plumb bob?* If you actually do, please say so. Put differently, if the walls of the Empire State Building were perfectly plumb, the top floor would be 3.9mm or 1/7" wider than the bottom floor. Again, do you think you would be able to see that at a glance? Be honest with yourself. Now, since we're talking about scale, back to my question: by how much would a skyscraper 50 miles away from you lean away from you? More or less than 10°? Just answer that.
I dont see the point of all this when we are getting live feeds from the International Space Station constantly as it orbits the earth every 90 minutes!

Yes, obviously, but since all the elevation data are relative to a WGS84 reference ellipsoid, the southern hemisphere will simply exhibit a very slightly higher average elevation.
@@okreylos How come all those pictures of the blue marble show it perfectly circular?
Because Earth has a diameter of 12,742km, or almost 8,000 miles. The southern hemisphere is about 100m wider, give or take, or 300 feet. That's a difference of 0.0008%. You actually think you would see that difference in a picture?
Lol. okay
Any updates on applying smoothing to the virtual camera's orientation?
Nicely done. Some may cherry pick a line from the conclusion where you say this doesn't prove the earth is round, and leave out the rest. It would be more accurate to say this one observation is consistent with a round earth (globe) and inconsistent with a flat earth. There is, of course, lots of other data supporting round over flat, which flat earth advocates conveniently ignore. It is the amount of similar evidence that proves the earth is a sphere.
That's neat
This effect is called refraction. It creates the illusion of rounding.

This is not proof. It is evidence. This piece of evidence points to a round earth, just like all of the other evidence we can find. The preponderance of evidence is 99.99% in favor of a round ball earth.

Gtreat work. Such simulations give the visual representation of complex problems. Thanks a million. I did Engineering and know most of the equations but now thanks to this demo I can conceptualize it far better. Thanks again.
What program did you used to merge the cameras ?
KinectViewer
Echo Vr had throwing down to a science.
No.
This is an unbelievable tutorial and explanation of how these VR system work. Great job. This is exactly what I was looking for. My default UE5 game does not have throwable items. How did you do the rotation of your character to be so lifelike!? Is that IK?
Glad you got something out of it. Yes, the avatar is IK-controlled, based solely on head- and controller-tracking and lots of heuristics.
TY for the response@@okreylos I just implemented the logic tonight like you said (get motion controller data, calculate distance/linear velocity) and the code works. I THINK I'm doing it right. The stock UE5 mechanics do EXACTLY what you talk about where the item just drops to the floor after you throw it. I have to double check the velocity with a graph like you did. Absolutely brilliant video thank you so much for the help.
If the Sun is so much larger than the Earth, and shines so strongly from 95 million miles away, how come there are hotspots on the surface of the Earth during the peak hot hours around midday to 2pm or so? There is a hotspot because the Sun is much smaller and closer to the Earth than we are told to believe. If the vacuum of space is such a good insulator, why is it freezing cold between the Sun and the Earth, but the heat of the Sun magically increases once the Sun rays reach the surface of the Earth? Heat cannot travel 95 million miles through the vacuum of space, it is simply impossible. A vacuum does not allow the transfer of heat, therefore the Sun cannot be 95 million miles away, and there cannot be an empty space (vacuum) between the Sun and the Earth. There are more than one way to prove that the Earth is flat and stationary, but you people control all online communications and censor any and everyone who tries to make any valid information available, why are you so afraid of the Truth? I know, because your father is a liar, and he hates the Truth.
"how come there are hotspots on the surface of the Earth during the peak hot hours" That's because Earth is a globe, and the parts of its surface that are directly "under" the Sun are facing the Sun directly, while the parts farther away are pointed away to the Sun by increasing amounts, meaning that they are heated less because the sunlight is glancing. It's not hard to understand.
"Heat cannot travel 95 million miles through the vacuum of space, it is simply impossible." That's wrong. There are three main ways in which heat can travel: via conduction, via convection, and via radiation. Conduction requires direct contact of two bodies; convection requires a movement of gas or liquid, so both of those are out, but radiation doesn't care about vacuum. In other words: heat is energy, and light is energy, so heat can be transported by light. If the light of the Sun can reach you through the vacuum of space, so can the Sun's heat. It's not hard to understand.
"you people control all online communications and censor any and everyone who tries to make any valid information available" Hold up, are you claiming that there *isn't* an entire sub-culture of flat Earth-espousing channels on UA-cam, or are you claiming that the information made available by those many, many channels is not valid?
@@okreylos Responding one thing at a time. 1. After traveling 95 million miles, are you going to tell me that if the Sun rays have to travel an extra 500 miles, its power is going to diminish so much to create a hotspot on the surface of the Earth? Fools are easily fooled, but those who can see through the lies, will know the answer to that. Hotspot are created only when the source of light or heat is very close to the receiving end, regardless of the shape of the receiving surface. 2. A double-pane window, helps to keep the heat of the Sun out of a home, with a gap less than 1" thin, yet NASA tells fools to accept that the 95 million mile gap of vacuum between the Sun and Earth, is insignificant, only an idiot could fall for that one. 3. Countless time, UA-cam, Facebook, Instagram, have and will remove comments that will contradict the so called "science", because they control the internet, and they can get away with it, don't you pretend to not know anything about it. If they would allow freedom of speech and expression, multitudes would come to the Truth, and they have, and that is why the censoring is so intense.
@@okreylos I wrote an answer to all your questions, and what did UA-cam do? They deleted it, because they don't want you or the rest of the world to know the Truth.
