Column mesh normals aren't normalized

[Netzwerk2]

Describe the bug The normals generated by ColumnMeshBuilder are not unit vectors.

To Reproduce

use hexx::{ColumnMeshBuilder, HexLayout};

fn main() {
    let mesh_info = ColumnMeshBuilder::new(&HexLayout::default(), 1.0).build();

    for normal in mesh_info.normals {
        println!("{}", normal.length());
    }
}

Expected behavior All normals should be of length 1.

Nice catch, that should be easy enough to fix soon.

What are the consequences of this? Is the lighting affected ?

[Netzwerk2]

I didn't test it, but yes it should affect lighting in bevy.

In my case I want to reflect a vector with respect to the normal, which gives wrong results if the normal isn't a unit vector.

@alice-i-cecile Have you noticed lighting issues in Emergence ? Does #109 bring any visual change to the game ?

[ManevilleF]

@Netzwerk2 Could you check if #109 fixes the issue for you ?

[Netzwerk2]

Yes, it works as expected now.
