The Beauty of Electromagnetic wave - FDTD visualization

A visualization of Finite-Difference Time-Domain simulation of the electromagnetic wave.

Simulation implemented in Python
Visualization in Blender3D

---

Additional information:

all simulation are done in a python program I wrote,
I learn a lot from him

When the simulation is done, all data is stored in image sequence,
one image provide 2 dimension (x, y),
by mapping the 2 dimension image into 3 dimension,
for example, for a 100 x 100 x 100 field
field (x, y, 0) = image (x, y)
field (x, y, 1) = image (x+100,y)
field (x, y, 2) = image (x+200, y)
field (x, y, z) = image (x+100*z, y)
with a 10000x100 size image, we can have 3D volumetric data stored in the 2D image.

The stored values are maps back onto 3D using blender nodes.

(Using OpenVDB should be much flexible but I didn't know how to use it.)

Great visualization! Incredibly beautiful!

the only thing I understand about this, is that it's awesome.

you are amazing, you should be way more popular

[stimpyfeelinit]

very impressive work
is there FDTD software that does it in 3D in real time?

Great work! how did you map the values in geometry nodes? I'm trying to do something similar - did you use 3d object? or perhaps surface? or particles? thanks

Hi hans, i didnt understand really that tweet where you showed the image files and how it works with it this is the only tuturial you can find on the internet maybe explaign it more on twitter or some other platform pls? thanks
