Struct nalgebra::Persp3 [−] [src]

pub struct Persp3<N> {
    // some fields omitted
}

A 3D perspective projection stored without any matrix.

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

Methods

`impl<N: BaseFloat> Persp3<N>`

`fn new(aspect: N, fov: N, znear: N, zfar: N) -> Persp3<N>`

Creates a new 3D perspective projection.

`fn to_mat(&self) -> Mat4<N>`

Builds a 4D projection matrix (using homogeneous coordinates) for this projection.

`fn to_persp_mat(&self) -> PerspMat3<N>`

Build a PerspMat3 representing this projection.

`impl<N: BaseFloat + Clone> Persp3<N>`

`fn aspect(&self) -> N`

Gets the width / height aspect ratio.

`fn fov(&self) -> N`

Gets the field of view of the view frustrum.

`fn znear(&self) -> N`

Gets the near plane offset of the view frustrum.

`fn zfar(&self) -> N`

Gets the far plane offset of the view frustrum.

`fn set_aspect(&mut self, aspect: N)`

Sets the width / height aspect ratio of the view frustrum.

This method does not build any matrix.

`fn set_fov(&mut self, fov: N)`

Sets the field of view of the view frustrum.

This method does not build any matrix.

`fn set_znear(&mut self, znear: N)`

Sets the near plane offset of the view frustrum.

This method does not build any matrix.

`fn set_zfar(&mut self, zfar: N)`

Sets the far plane offset of the view frustrum.

This method does not build any matrix.

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

Projects a point.

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

Projects a vector.
