#[repr(C)]
pub struct Perspective3<T> { /* private fields */ }

A 3D perspective projection stored as a homogeneous 4x4 matrix.

Implementations

impl<T> Perspective3<T>

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

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

It is not checked whether or not the given matrix actually represents a perspective projection.

impl<T: RealField> Perspective3<T>

pub fn new(aspect: T, fovy: T, znear: T, zfar: T) -> Self

Creates a new perspective matrix from the aspect ratio, y field of view, and near/far planes.

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

Retrieves the inverse of the underlying homogeneous matrix.

pub fn to_homogeneous(self) -> Matrix4<T>

Computes the corresponding homogeneous matrix.

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

A reference to the underlying homogeneous transformation matrix.

pub fn as_projective(&self) -> &Projective3<T>

A reference to this transformation seen as a Projective3.

pub fn to_projective(self) -> Projective3<T>

This transformation seen as a Projective3.

pub fn into_inner(self) -> Matrix4<T>

Retrieves the underlying homogeneous matrix.

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

👎Deprecated: use .into_inner() instead

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

pub fn aspect(&self) -> T

Gets the width / height aspect ratio of the view frustum.

pub fn fovy(&self) -> T

Gets the y field of view of the view frustum.

pub fn znear(&self) -> T

pub fn zfar(&self) -> T

Gets the far plane offset of the view frustum.

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

Projects a point. Faster than matrix multiplication.

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

Un-projects a point. Faster than multiplication by the matrix inverse.

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

where SB: Storage<T, U3>,

Projects a vector. Faster than matrix multiplication.

pub fn set_aspect(&mut self, aspect: T)

Updates this perspective matrix with a new width / height aspect ratio of the view frustum.

pub fn set_fovy(&mut self, fovy: T)

Updates this perspective with a new y field of view of the view frustum.

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

Updates this perspective matrix with a new near plane offset of the view frustum.

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

Updates this perspective matrix with a new far plane offset of the view frustum.

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

Updates this perspective matrix with new near and far plane offsets of the view frustum.

Trait Implementations

impl<T> Archive for Perspective3<T>

where T: Archive, Matrix4<T>: Archive<Archived = Matrix4<T::Archived>> + Archive,

type Archived = Perspective3<<T as Archive>::Archived>

The archived representation of this type.

type Resolver = Perspective3Resolver<T>

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: Self::Resolver, out: *mut Self::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl<T: Clone> Clone for Perspective3<T>

fn clone(&self) -> Perspective3<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: RealField> Debug for Perspective3<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'a, T: RealField + Deserialize<'a>> Deserialize<'a> for Perspective3<T>

fn deserialize<Des>(deserializer: Des) -> Result<Self, Des::Error>

where Des: Deserializer<'a>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized, T> Deserialize<Perspective3<T>, __D> for Archived<Perspective3<T>>

where T: Archive, Matrix4<T>: Archive<Archived = Matrix4<T::Archived>> + Archive, Archived<Matrix4<T>>: Deserialize<Matrix4<T>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<Perspective3<T>, __D::Error>

Deserializes using the given deserializer

impl<T: RealField> From<Perspective3<T>> for Matrix4<T>

fn from(pers: Perspective3<T>) -> Self

Converts to this type from the input type.

impl<T: RealField> PartialEq for Perspective3<T>

fn eq(&self, right: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<__S: Fallible + ?Sized, T> Serialize<__S> for Perspective3<T>

where T: Archive, Matrix4<T>: Archive<Archived = Matrix4<T::Archived>> + Serialize<__S>,

fn serialize(&self, serializer: &mut __S) -> Result<Self::Resolver, __S::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl<T: RealField + Serialize> Serialize for Perspective3<T>

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<T: Copy> Copy for Perspective3<T>
