Camera definition for 3D rendering.

Fields

position: Vec3

World-space camera position.

target: Vec3

World-space point the camera looks at.

up: Vec3

World-space up vector.

fov_y: f32

Field of view in radians (perspective) or half-height (orthographic).

near: f32

Near clipping plane distance.

far: f32

Far clipping plane distance.

perspective: bool

If true, use perspective projection. If false, use orthographic.

aspect: f32

Aspect ratio (width / height). Used for perspective projection.

Implementations
