pub struct Orthographic3<N: Real> { /* fields omitted */ }

A 3D orthographic projection stored as an homogeneous 4x4 matrix.

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

The largest x-coordinate of the view cuboid.

pub fn bottom(&self) -> N

The smallest y-coordinate of the view cuboid.

pub fn top(&self) -> N

The largest y-coordinate of the view cuboid.

pub fn znear(&self) -> N

The near plane offset of the view cuboid.

pub fn zfar(&self) -> N

The far plane offset of the view cuboid.

pub fn project_point(&self, p: &Point3<N>) -> Point3<N>

Projects a point. Faster than matrix multiplication.

pub fn unproject_point(&self, p: &Point3<N>) -> Point3<N>

pub fn project_vector<SB>(&self, p: &Vector<N, U3, SB>) -> Vector3<N> where
    SB: Storage<N, U3>, 

Projects a vector. Faster than matrix multiplication.

pub fn set_left(&mut self, left: N)

pub fn set_znear(&mut self, znear: N)

Sets the near plane offset of the view cuboid.

pub fn set_zfar(&mut self, zfar: N)

Sets the far plane offset of the view cuboid.

pub fn set_left_and_right(&mut self, left: N, right: N)

Sets the view cuboid coordinates along the x axis.

pub fn set_bottom_and_top(&mut self, bottom: N, top: N)

Sets the view cuboid coordinates along the y axis.

pub fn set_znear_and_zfar(&mut self, znear: N, zfar: N)
