Young's double-slit experiment with waves: phase representation in 3D

This simulation has two parts, showing the same evolution with two different cyclic color gradients:
Jet color gradient: 0:00
Twilight color gradient: 0:57
The somewhat psychedelic Jet gradient gives a very colorful result, but is sometimes criticized because it is not perceptually uniform (some hues appear over-represented). The twilight gradient is a more discreet alternative.
The boundary conditions in the simulation are absorbing on the sides of the displayed rectangular region, but they do not work perfectly, which is why one sees some waves reflected on the sides in the first part.

Render time: 45 minutes 40 seconds
Color scheme: Part 1 - Jet
Part 2 - Twilight by Bastian Bechtold

Music: "Making Rounds" by Silent Partner

Many thanks to my colleague Marco Mancini for helping me to accelerate my code!

We need the Nils Burgland simulation of the EmDrive, really but that nonsense to bed

i prefer the jet colour scheme, easier to distinguish the 3D contours for me :) nice video

Maybe the holes are solutions to polynomials. So, one is r_1 and the other r_2. a=1, and c is either very close to negative one (decay) or negative one. Zero is somewhere between the two, probably not in at the halfway point. We draw a line from zero to an intersection on the wall. That angle will be a rational angle of pi.

now I'm wondering what you would get if you did a double slit experiment with all of the walls being electron sensors; the walls on both sides of the slit barrier.

Recently a religious bigot told me that particles never behave wave-like (they needed this premise for an argument for the existence of their imaginary god). After i literally showed them the double slit experiment they were baffled.
