Femto camera to measure for space, moving aether

There is absolutely nothing in the article to indicate it used any real photos or the like.
There is absolutely nothing in the article to indicate it is anything other than a simulation.

So the algorthms used to dictate the simulation were made up at random  Do you even know what a 3D model is?

No, they were based upon light travelling in a straight line at a constant speed, dependent upon the medium.
That isn't made up at random. But it still a simulation.
The product of this simulation is based entirely upon what is put into it.
If you wanted to put in light which travels at the same velocity regardless of which reference frame you use (i.e. no aether, note: this doesn't mean regardless of medium) then it will produce results consistent with that. If you wanted to put in light which travels through a medium at a velocity relative to that medium (i.e. aether), then it will produce results consistent with that. You could even put in light which travels through the aether, but can be dragged by other mediums without being dragged by other mediums (e.g. Airy's failure) and it will produce results consistent with that inconsistency.

The point is that it is a simulation.
You can't say in reality we would expect X if Y is true. This simulation shows X. Thus Y is true.
All it would do is show Y is true in the simulation, NOT REALITY!

Do you understand that?

Why do you keep bringing up 3D? The simulation we are discussing is 2D.

Just assumed as fact.

"Luckily, 2D light transport does not have this problem: Since the entirety of the path is always visible to the camera, adding a finite shutter time simply amounts to "cutting out" the part of the path that falls within [t0, t1]. This leads to an embarassingly simple algorithm that we can add on top of our existing 2D renderer with only a few lines of code."

So the camera used is a virtual camera, read up on those, its basically computer animation mixed with reality like a weatherman uses. It's still a real camera that creates the algorithm sampling from real images! like that of light moving across objects.

No it isn't.
It is a virtual camera, a camera which exists in a virtual world. i.e. a simulation.
It is purely a simulation. There is no real camera involved.

Just because some company has marketed a product called Virtual Camera doesn't mean all virtual cameras suddenly become real.

There's a lot of misinformation and misinterpretation in this thread, but some items that bear pointing out are:

1) Yes, a camera exists that can take more than a trillion images per second (~ 10 trillion per second). Using it, one can observe changes in the speed of light.
2) Given sufficient number of frames and sufficient accuracy, one could measure the speed of light in different configurations and the supposed effect of "aether."
3) There are other ways to measure the speed of light. Suggesting that doing it with a very complex imaging system, and then performing the final step with "just an image and a ruler" shows extreme naivete.
4) The "Virtual Femto Photography" YouTube video is a computer simulation, not a video of a light pulse.
5) An actual video of a light pulse is shown here:

6) While the majority of streak cameras work as described in Reply #19, the camera above can capture a single shot event at a frame rate of 10 trillion/sec.
