I've been a LOOONG time POVRay user and in the past year have been using POVRay
to help visualize the electromagnetic fields within EMDrive simulations.  The
full playlist is here:

but the best of the lot - highest density anyway - is here:
https://youtu.be/9mxpEtkCxNc
These are generated from a tool called 'meep' from MIT which does
electromagnetic and optical cavity simulations.  These generate HDF files which
I then export slices from and save as CSV files (using standard HDF tools).  I
wrote a C++ program to convert the CSV files to a POVRay ".inc" file.
More on my investigations into the EMDrive with links to the C++ tool are here:

Thanks to everybody who helps keep POVRay alive :)

Great thing if EM Drive can be done.

Reminds me of collapsing magnetic fields of wire windings or "coils" used for
engine spark plug firings.

Wonder how natural magnetic fields (Earth, Sun, etc.) would affect it when
moving at high speeds?

Almost 40 years ago I wrote a science fiction short story, only submitted to
OMNI magazine and never published. Interstellar space ship used a similar thing,
but gathered the diffuse particles and photons of deep space at fractional light
speed to power it.
Acted as both barrier field and propulsion.  :)

I have no idea what I'm looking at.
