Struct duku::Camera

pub struct Camera {
    pub position: Vec3,
    pub scale: Vec3,
    pub rotation: Quat,
    pub fov: u32,
    pub width: Option<f32>,
    pub height: Option<f32>,
    pub depth: f32,
    pub projection: Projection,
}

The view into a scene.

Examples

let camera = Camera::perspective(90);

duku.draw(Some(&camera), |t| {
    // draw commands
});

Fields

position: Vec3

the position of the camera

scale: Vec3

the scale of the camera

rotation: Quat

the rotation of the camera

fov: u32

field of view for perspective cameras

width: Option<f32>

the width of the camera, if width is None the camera will be automatically sized based on the render texture or window

height: Option<f32>

the height of the camera, if height is None the camera will be automatically sized based on the render texture or window

depth: f32

the depth of the camera

projection: Projection

the projection type of the camera
