Struct nalgebra::OrthoMat3

pub struct OrthoMat3<N> {
    // some fields omitted
}

A 3D orthographic projection stored as a 4D matrix.

Reading or modifying its individual properties is costly but applying the transformation is cheap.

Methods

impl<N: BaseFloat> OrthoMat3<N>

fn new(width: N, height: N, znear: N, zfar: N) -> OrthoMat3<N>

Creates a new orthographic projection matrix from the width, heihgt, znear and zfar planes of the view cuboid.

unsafe fn new_with_mat(mat: Mat4<N>) -> OrthoMat3<N>

Creates a new orthographic matrix from a 4D matrix.

This is unsafe because the input matrix is not checked to be a orthographic projection.

fn as_mat<'a>(&'a self) -> &'a Mat4<N>

Returns a reference to the 4D matrix (using homogeneous coordinates) of this projection.

fn width(&self) -> N

The width of the view cuboid.

fn height(&self) -> N

The height of the view cuboid.

fn znear(&self) -> N

The near plane offset of the view cuboid.

fn zfar(&self) -> N

The far plane offset of the view cuboid.

fn set_width(&mut self, width: N)

Sets the width of the view cuboid.

fn set_height(&mut self, height: N)

Sets the height of the view cuboid.

fn set_znear(&mut self, znear: N)

Sets the near plane offset of the view cuboid.

fn set_zfar(&mut self, zfar: N)

Sets the far plane offset of the view cuboid.

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

Sets the near and far plane offsets of the view cuboid.

fn project_pnt(&self, p: &Pnt3<N>) -> Pnt3<N>

Projects a point.

fn project_vec(&self, p: &Vec3<N>) -> Vec3<N>

Projects a vector.

impl<N: BaseFloat + Clone> OrthoMat3<N>

fn to_mat<'a>(&'a self) -> Mat4<N>

Returns the 4D matrix (using homogeneous coordinates) of this projection.
