Fields

fov_y: f32

aspect: f32

near: f32

far: f32

position: Vec3

Position shifts all points prior to the camera transform; this is what we adjust with move keys.

orientation: Quaternion

proj_mat: Mat4

We store the projection matrix here since it only changes when we change the camera cfg.

fog_density: f32

These are in distances from the camera. E scale within band. 1.0 is a good baseline.

fog_power: f32

Curve steepness, e.g. 4–8. Higher means more of a near “wall” with heavy far fade.

fog_start: f32

distance where fog begins

fog_end: f32

Distance where fog reaches full strength

fog_color: [f32; 3]

edge_cueing: f32

Strength of edge cueing (silhouette darkening). 0.0 = off, 1.0 = full effect. Controlled at startup via GraphicsSettings::edge_cueing.

halo_expansion: f32

World-space expansion along normals used in the depth-aware halo prepass. 0.0 = disabled. Set from GraphicsSettings::depth_aware_halos.

Implementations

impl Camera

pub fn to_bytes(&self) -> [u8; 128]

pub fn update_proj_mat(&mut self)

Updates the projection matrix based on the projection parameters. Run this after updating the parameters.

pub fn view_mat(&self) -> Mat4

Calculate the view matrix: This is a translation of the negative coordinates of the camera’s position, applied before the camera’s rotation.

pub fn view_size(&self, far: bool) -> (f32, f32)

pub fn in_view(&self, point: Vec3) -> (bool, (f32, f32, f32))

Determines if an object is in view. Also returns NDC coordinates, for use in some applications.

Trait Implementations

impl Clone for Camera

fn clone(&self) -> Camera

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Camera

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Camera

fn default() -> Self

Returns the “default value” for a type.
