Struct nalgebra::Ortho3
[−]
[src]
pub struct Ortho3<N> {
// some fields omitted
}A 3D orthographic projection stored without any matrix.
Reading or modifying its individual properties is cheap but applying the transformation is costly.
Methods
impl<N: BaseFloat> Ortho3<N>
fn new(width: N, height: N, znear: N, zfar: N) -> Ortho3<N>
Creates a new 3D orthographic projection.
fn to_mat(&self) -> Mat4<N>
Builds a 4D projection matrix (using homogeneous coordinates) for this projection.
fn to_persp_mat(&self) -> OrthoMat3<N>
Build a OrthoMat3 representing this projection.
impl<N: BaseFloat + Clone> Ortho3<N>
fn width(&self) -> N

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)
