Retrieves the inverse of the underlying homogeneous matrix.

pub fn to_homogeneous( self ) -> Matrix<T, Const<nalgebra::::base::dimension::U4::{constant#0}>, Const<nalgebra::::base::dimension::U4::{constant#0}>, ArrayStorage<T, 4, 4>>

Computes the corresponding homogeneous matrix.

pub fn unwrap( self ) -> Matrix<T, Const<nalgebra::::base::dimension::U4::{constant#0}>, Const<nalgebra::::base::dimension::U4::{constant#0}>, ArrayStorage<T, 4, 4>>

👎Deprecated: use .into_inner() instead

Retrieves the underlying homogeneous matrix. Deprecated: Use Perspective3::into_inner instead.
