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

Implementations

impl<T> Perspective3<T>

pub const fn from_matrix_unchecked( matrix: Matrix<T, Const<4>, Const<4>, ArrayStorage<T, 4, 4>>, ) -> Perspective3<T>

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> Perspective3<T>

where T: RealField,

pub fn new(aspect: T, fovy: T, znear: T, zfar: T) -> Perspective3<T>

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

pub fn inverse(&self) -> Matrix<T, Const<4>, Const<4>, ArrayStorage<T, 4, 4>>

Retrieves the inverse of the underlying homogeneous matrix.

pub fn to_homogeneous( self, ) -> Matrix<T, Const<4>, Const<4>, ArrayStorage<T, 4, 4>>

Computes the corresponding homogeneous matrix.

pub fn as_matrix(&self) -> &Matrix<T, Const<4>, Const<4>, ArrayStorage<T, 4, 4>>

A reference to the underlying homogeneous transformation matrix.

pub fn as_projective(&self) -> &Transform<T, TProjective, 3>

A reference to this transformation seen as a Projective3.

pub fn to_projective(self) -> Transform<T, TProjective, 3>

This transformation seen as a Projective3.

pub fn into_inner(self) -> Matrix<T, Const<4>, Const<4>, ArrayStorage<T, 4, 4>>

Retrieves the underlying homogeneous matrix.

pub fn unwrap(self) -> Matrix<T, Const<4>, Const<4>, ArrayStorage<T, 4, 4>>

👎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

Gets the near plane offset of the view frustum.

pub fn zfar(&self) -> T

Gets the far plane offset of the view frustum.

pub fn project_point(&self, p: &OPoint<T, Const<3>>) -> OPoint<T, Const<3>>

Projects a point. Faster than matrix multiplication.

pub fn unproject_point(&self, p: &OPoint<T, Const<3>>) -> OPoint<T, Const<3>>

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

pub fn project_vector<SB>( &self, p: &Matrix<T, Const<3>, Const<1>, SB>, ) -> Matrix<T, Const<3>, Const<1>, ArrayStorage<T, 3, 1>>

where SB: Storage<T, Const<3>>,

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
