[][src]Struct nalgebra::geometry::Perspective3

pub struct Perspective3<N: Scalar> { /* fields omitted */ }

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

Methods

impl<N: RealField> Perspective3<N>[src]

pub fn new(aspect: N, fovy: N, znear: N, zfar: N) -> Self[src]

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

pub fn from_matrix_unchecked(matrix: Matrix4<N>) -> Self[src]

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

It is not checked whether or not the given matrix actually represents an orthographic projection.

pub fn inverse(&self) -> Matrix4<N>[src]

Retrieves the inverse of the underlying homogeneous matrix.

pub fn to_homogeneous(&self) -> Matrix4<N>[src]

Computes the corresponding homogeneous matrix.

pub fn as_matrix(&self) -> &Matrix4<N>[src]

A reference to the underlying homogeneous transformation matrix.

pub fn as_projective(&self) -> &Projective3<N>[src]

A reference to this transformation seen as a Projective3.

pub fn to_projective(&self) -> Projective3<N>[src]

This transformation seen as a Projective3.

pub fn into_inner(self) -> Matrix4<N>[src]

Retrieves the underlying homogeneous matrix.

pub fn unwrap(self) -> Matrix4<N>[src]

Deprecated:

use .into_inner() instead

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

pub fn aspect(&self) -> N[src]

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

pub fn fovy(&self) -> N[src]

Gets the y field of view of the view frustum.

pub fn znear(&self) -> N[src]

Gets the near plane offset of the view frustum.

pub fn zfar(&self) -> N[src]

Gets the far plane offset of the view frustum.

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

Projects a point. Faster than matrix multiplication.

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

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

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

Projects a vector. Faster than matrix multiplication.

pub fn set_aspect(&mut self, aspect: N)[src]

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

pub fn set_fovy(&mut self, fovy: N)[src]

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

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

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

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

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

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

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