THIS OPTIONAL THING IS FUCKING ANNOYING

double angleTo(const vector3d& v, const std::optional& n = std::nullopt) const { // q.v. stackoverflow.com/questions/14066933#answer-16544330, but n·p₁×p₂ is numerically // ill-conditioned, so just calculate sign to apply to |p₁×p₂| // if n·p₁×p₂ is -ve, negate |p₁×p₂|

const int sign = n == std::nullopt || cross(v).dot(*n) >= 0 ? 1 : -1;

// const int sign = n == std::nullopt || cross(v).dot(*n) >= 0 ? true : false;

const double sintheta = cross(v).length() * sign;
const double costheta = dot(v);
return std::atan2(sintheta, costheta);

}

DONT MAKE CODE UNNECESSARY COMPLEX !!!!

i am sure you using some gcc garbage from the past... BLEH

Anyway setting C++17 language in visual studio wasn't enough...

apperently some shitty flag must be added too:

In Visual Studio need add flag /std:c++17 to Debug -> Project Properties -> C/C++ -> All options -> Additional Options – Elmir Dec 4, 2021 at 22:32

Not tried yet gonna try it... :PPPP***8

I HAVE BETTER THINGS TO DO THAN WASTE MY LIFE ON SETTING THESE KINDS OF STUPID MAKE AND OPTION GARBAGE THINGS BYEEEE.

[SkybuckFlying]

APPERENTLY VISUAL STUDIO DOESN'T TAKE ME TO THE DEBUG OPTIONS WJHEN THE DEBUG BUILD IS SET...

IT TOOK ME TO RELEASE OPTIONS... THAT'S PROBABLY WHY IT DIDNT WORK...

A;PPERENTLY I MUST SET THE C++ LANGUAGE TO VERSION 17 IN RELEASE

AND AAAAGGGGAAAIN IN DEBUG....

WHO THE FUCK DEBUGS VERSION 14 AND THEN BUILDS IN VERSION 17 OR VICA VERSA IT DOESNT MAKE ANY FUCKING SENSE.. IAM SURE THERE IS USE CASE BUT STILL OHM MY FUCKING GOD

BYEEEE.

THIS IS PROBABLY ERRORS FROM THE MISSING ALGORITHM FILES:

AAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHBBBBBBBBBBBBBYYYYYYYEEEEEEEEEEEE

[SkybuckFlying]

HAH I JUST NUKE IT AND DELETE THOSE GARBAGE FUNCTIONS DONT NEED EM... JUST NEED A LITTLE BIT TO NVECTOPR OR WHATEVER THE FUCK NEED ANGLE OH MTY GBYEEEE

[SkybuckFlying]

I converted the necessary code to Delphi...
