A photographic lens type.

Required methods

pub fn depth(&self) -> &Range<f32>

Returns the camera z-depth range.

pub fn overlaps_cone(&self, cone: Cone) -> bool

Returns true if the given cone can possibly be seen by this camera. Note that this function may be conservative as implementations are not required do use fully accurate geometric tests.

pub fn overlaps_point(&self, p: Vec3) -> bool

Returns true if the given point can possibly be seen by this camera.

pub fn overlaps_sphere(&self, sphere: Sphere) -> bool

Returns true if the given sphere can possibly be seen by this camera.

pub fn eye(&self) -> Vec3

Gets the camera viewpoint position.

pub fn project_point(&self, p: Vec3) -> Vec3

TODO: Maybe remove?

pub fn projection(&self) -> Mat4

Gets the pre-calculated projection matrix.

pub fn unproject_point(&self, p: Vec3) -> Vec3

TODO: Maybe remove?

pub fn view(&self) -> Mat4

Gets the pre-calculated view matrix.

pub fn view_inv(&self) -> Mat4

Gets the pre-calculated inverse view matrix.
