    pub fov_deg: f32,
    pub near: f32,
    pub far: f32,
}

Fields

pub position: Vec3

Where the camera is.

pub target: Vec3

The point it looks at.

pub fov_deg: f32

Vertical field of view, in degrees.

pub near: f32

The near clipping plane's distance.

pub far: f32

The far clipping plane's distance.

pub fn view(&self) -> Mat4

The view matrix: from the world to the camera.

pub fn projection(&self, aspect: f32) -> Mat4

The perspective projection for a surface of aspect (width / height).

pub fn view_projection(&self, aspect: f32) -> Mat4

Projection and view together.
