Struct Mat4 

#[repr(C)]
pub struct Mat4 {
    pub x_axis: Vec4,
    pub y_axis: Vec4,
    pub z_axis: Vec4,
    pub w_axis: Vec4,
}

A 4x4 column major matrix.

If you are primarily dealing with 3D affine transformations considering using Affine3A which is faster than a 4x4 matrix for some affine operations.

Affine transformations including 3D translation, rotation and scale can be created using methods such as Self::from_translation(), Self::from_quat(), Self::from_scale() and Self::from_scale_rotation_translation().

The Self::transform_point3() and Self::transform_vector3() convenience methods are provided for performing affine transformations on 3D vectors and points. These multiply 3D inputs as 4D vectors with an implicit w value of 1 for points and 0 for vectors respectively. These methods assume that Self contains a valid affine transform.

SIMD vector types are used for storage on supported platforms.

This type is 16 byte aligned.
