In what units do you measure the volume?
If I want to obtain height, width and length, should I implement a handler?
Do vectors have no units?

[ChubV]

STL files do not have a unit. The actual size depends on the actual program you use for the interpretation. So you can scale it both to nanometers or light years.

Yeah, handlers are the best way to obtain any model-related measurements.

[MrFiregore]

by default what is the volumen unit?

[ChubV]

It depends on the software you're using to create the model or to print it. So look at the settings of your software. Most of the soft use mm as the default units, but you can customize it to scale your model.

I do not have any software for rendering.
My operating system is Windows 10.
I send captures of the obtained results.

With other page:

With your library:

The stl : https://cdn.thingiverse.com/assets/ef/b1/13/86/ef/MatM_Iron_Man_Helmet.stl

So 107532274 and 107433137 is kinda 0,09% difference which may be caused by rounding or the method of volume calculations.

[MrFiregore]

ok, I have learned more about STL file and how it works...
You're in the truth, but it could be solved with ini_set('precision', 16);

This thread was unrelated to documentation, but ti would be good to have a little bit more info either in the README or a dedicated file. I will consider adding this after I have worked with the library some more.
