Sorry, i feel urged to answer that:
> But the projection is irrelevant and YES a 6000 x 3000 images regardless of it's projection or content IS 18 megapixels. Stop trying to make issues where none exist.
Such type of answer was given to B. Mandelbrot by the established
science community in response to his fractal theory. And today, the
first time in history, we are able to describe nature phenomens - by
using "fractal dimensions" (

> It's the same as a megapixel, these terms are simply units that represent a quantity just like a litre, gallon, mile, kilometre etc.
> It's like trying to argue how long a mile is based on the type of car and speed I'm driving to cover it.
Every unit measurement (eg. kg) needs a reference (lies in Paris) and
method (on Earth). See the coastline example in the above link.
Same for panoramas. A user could argue that he is never able to see 18
megapixels in the viewer. And a cubic source has another pixel count
than an equirectangular one - with the same visual result.
I think, the discussion to find an independent magnitude is very valid
