There is no computer program out there that is going to know what to do if you tell it to draw a laser beam through milk in slow motion.
Would you like to quote the bit you think says you are right?
Nobody said there would.You made that bit up.

Let's look at what they actually say."we created a virtual camera that was fast enough""we could capture light as it spreads through the virtual scene"" 2D light transport simulator ""Monte Carlo raytracing""we assign our virtual camera""To keep track of time along light paths, I will be using a slightly modified geometric optics model""on top of our existing 2D renderer with only a few lines of code.""we use a conventional 2D renderer""We annotate each vertex on these light paths with a timestamp""store these in memory""we iterate over all segments""splat the line segment to the screen""we could do it in a vertex shader"OK, all of those show that the article is talking about computer graphic simulation, not anything real.But the most interesting line is "Note the strong color separation in the first video: Because the index of refraction depends on the wavelength, different wavelengths travel at different speeds through the glass and begin to separate after the first refraction."Because that's what explains the fact that the image isn't circular.One side has a higher refractive index, so the light spreads less far.
OK, if it's a film of a real laser hitting real milk, how come the milk starts off as a vertical line?In the real universe it would form a a chain of drops and fall down.
filming light with a camera to me.
Ok I bet you know what every thing you just quoted means from your cube drawing days.
And it sounds like they are doing monte carlo ray tracing to me- because that's what they say they are doing.And ray tracing is a way to make computer generated images.https://en.wikipedia.org/wiki/Path_tracing

So the video you posted is, whether you like it or not, a computer animation.
ou only learned about as I pointed it out to you.
Well of course what you really mean is the video is fake to satisfy your need to be unconditionally right.
You know its a little insulting to listen to a pompous POS like you
Why don't you step back.
what other experiments?
I took Computer drafting for four semesters.
Do you even understand how computer animation works? You would either need a picture of animation in question or have to make a hand drawing of it.

I think most of us are having difficulty reconciling these 2 statements:Quote from: trevorjohnson32 on 18/05/2019 17:17:31I took Computer drafting for four semesters.

Nobody mentioned diffraction here. Did you mean refraction?
