Struct Camera 

pub struct Camera {
    pub transform: Matrix4<f32>,
    pub projection: Projection,
    pub zfar: f32,
    pub znear: f32,
}

Contains camera properties.

Fields

transform: Matrix4<f32>

Transform matrix (also called world to camera matrix)

projection: Projection

Projection type and specific parameters

zfar: f32

The distance to the far clipping plane.

For perspective projection, this may be infinite.

znear: f32

The distance to the near clipping plane.

Implementations

impl Camera

pub fn position(&self) -> Vector3<f32>

Position of the camera.

pub fn right(&self) -> Vector3<f32>

Right vector of the camera.

pub fn up(&self) -> Vector3<f32>

Up vector of the camera.

pub fn forward(&self) -> Vector3<f32>

Forward vector of the camera (backside direction).

pub fn apply_transform_vector(&self, pos: &Vector3<f32>) -> Vector3<f32>

Apply the transformation matrix on a vector.

Example

let ray_dir = Vector3::new(1., 0., 0.);
let ray_dir = cam.apply_transform_vector(&ray_dir);

Trait Implementations

impl Clone for Camera

fn clone(&self) -> Camera

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.
