Methods

impl<N: Real> Orthographic3<N>

pub fn new(left: N, right: N, bottom: N, top: N, znear: N, zfar: N) -> Self

Creates a new orthographic projection matrix.

pub fn from_matrix_unchecked(matrix: Matrix4<N>) -> Self

Wraps the given matrix to interpret it as a 3D orthographic matrix.

It is not checked whether or not the given matrix actually represents an orthographic projection.

pub fn from_fov(aspect: N, vfov: N, znear: N, zfar: N) -> Self

Creates a new orthographic projection matrix from an aspect ratio and the vertical field of view.

pub fn inverse(&self) -> Matrix4<N>

Retrieves the inverse of the underlying homogeneous matrix.

pub fn to_homogeneous(&self) -> Matrix4<N>

Computes the corresponding homogeneous matrix.

pub fn as_matrix(&self) -> &Matrix4<N>

A reference to the underlying homogeneous transformation matrix.

pub fn unwrap(self) -> Matrix4<N>

Retrieves the underlying homogeneous matrix.

pub fn left(&self) -> N

The smallest x-coordinate of the view cuboid.

pub fn right(&self) -> N
