Struct Vec4 

#[repr(C)]
pub struct Vec4 {
    pub x: f32,
    pub y: f32,
    pub z: f32,
    pub w: f32,
}

A 4-dimensional vector with f32 components, often used for homogeneous coordinates.

In 3D graphics, Vec4 is primarily used to represent points (w=1.0) and vectors (w=0.0) in homogeneous space, allowing them to be transformed by a Mat4.

Fields

x: f32

The x component of the vector.

y: f32

The y component of the vector.

z: f32

The z component of the vector.

w: f32

The w component, used for homogeneous coordinates.
