Expand description

A spot (cone) light — a PointLight with a direction and a soft angular cutoff, so it lights only a cone. World space. Internally folded into the point-light path (a point light is the 180°-cone degenerate), so spots share the point-light count + shadow-caster budgets.

Fields§

§position: [f32; 3]

World-space position (voxel units).

§direction: [f32; 3]

Cone axis — the direction the light shines along (the way the light travels). Need not be normalized; the backend normalizes.

§color: [f32; 3]

Linear RGB, 0..1.

§intensity: f32

Scalar brightness multiplier on color.

§radius: f32

Hard cutoff distance in world units; past it the light is zero.

§inner_angle_deg: f32

Inner half-angle in degrees: within it the cone is at full brightness. Clamped to 0..=outer_angle_deg.

§outer_angle_deg: f32

Outer half-angle in degrees: past it the cone is zero; between the two it soft-falls off (smoothstep). outer == inner ⇒ a hard edge; >= 180 ⇒ omnidirectional (a plain point light). Clamped to 0..=180.

§casts_shadow: bool

Whether this spot casts a stylized hard shadow (shares the shadow-caster cap with the sun + point lights; excess demoted with a warning, never truncated).
