but I’ve accepted defeat in trying to understand it
I may have shared the link but even I don’t know how it how it works.
It’s like admiring the Eiffel Tower; you can understand that it’s a marvel of engineering without understanding the underlying engineering concepts. Such experiences are rare but they truly humble you.
Regarding the square root, understand the following concepts
- Bit shifting simply shift the bits to a certain side (Left or right) =>
0010 << 1 → 0100
- Mathematically, it multiplies or divides the input number with a factor of 2, depending upon the type of shift
- If you shift the number
n
with a nice shift amountx
(I have greatly greatly over-simplified this), then you can calculate the inverse sq. root since inverse square root is2^(-1/2)
- Calculating the inverse square root manually will take lots of clock cycles, which was not feasible for a FPS game with the limited h/w
- Bit shifting is a lot faster since we are not computing, but instead shifting
The resultant shifting gives us an answer which is close enough to the answer, and that is good enough for FPS games for calculation of reflections.
PS: Someone who is more experienced in this domain can correct me if I’m wrong.

I am still in awe of the fast inverse square root method used in QuakeIII. Good times.

Correct. That’s why I said symbolically.
but you never see the character on screen again
I maybe incorrect but towards the end of the movie, the Emperor asks how Katsumoto died, to which Tom Cruise replies “I’ll tell you how he lived”. So he was alive?
- Comment on Ubi, it's $70 and people are vary of your mile wide puddles that drop 75% in price after half a year 4 weeks ago:
I might be terribly incorrect.
But i remember that Tom Cruise’s character switches sides in the movie after spending time with the Samurai (He was captured by them). He trains under them and becomes a Samurai. In the end, they fight against the (British?) and lose due to a gattling gun. All the Samurai die except for Tom’s character. So symbolically, Tom is the Last Samurai.

It’s a custom ROM (crDroid 11). It might be using Substratum but it’s done in such a seamless manner that I don’t even know.
I tried it long back during Android 9-10 and it was buggy.
