Struct Camera

pub struct Camera {
    pub fov_y: f32,
    pub aspect: f32,
    pub near: f32,
    pub far: f32,
    pub position: Vec3,
    pub orientation: Quaternion,
    pub proj_mat: Mat4,
}

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.

Implementations

impl Camera

pub fn to_bytes(&self) -> [u8; 80]

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)

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.
