Struct Camera 

pub struct Camera {
    pub eye: Vec3,
    pub target: Vec3,
    pub up: Vec3,
    pub projection: Projection,
}

A look-at camera in world space (right-handed, +Y up, looking down −Z in its own view space).

Fields

eye: Vec3

Eye position, world space.

target: Vec3

Point the camera looks at, world space.

up: Vec3

Up hint; need not be orthogonal to the view direction.

projection: Projection

The view-to-clip mapping.

Implementations

impl Camera

pub fn look_at(eye: Vec3, target: Vec3, up: Vec3) -> Mat4

Builds a right-handed world-to-view look-at transform.

pub fn framing_aabb(bound: &Aabb, aspect: f32) -> Self

Frames a world-space box tightly from the +Z axis with deterministic padding. This avoids the excess empty space introduced by first enclosing an anisotropic molecule in a sphere.

pub fn framing(bound: &BoundingSphere, aspect: f32) -> Self

A camera looking at bound from a distance that frames it fully, down the +Z axis with +Y up.

pub fn view(&self) -> Mat4

The view-from-world matrix.

pub fn view_proj(&self) -> Mat4

The clip-from-world matrix: projection composed with view, in that order, always.

pub fn frustum_planes(&self) -> [Vec4; 6]

The six frustum planes of view_proj, as (normal, d) packed into Vec4 with the inside satisfying dot(n, p) + d >= 0. Order: left, right, bottom, top, near, far.

pub fn focus_distance(&self) -> f32

Distance from eye to target.
