Clustered lights
The default Scene graph runs a clustered compute pass before its HDR forward passes. Light handles write flat rows consumed by that pass.
const point = new PointLight(scene, {
position: [0, 1, 1],
color: [1, 0.25, 0.05],
intensity: 20,
range: 8,
radius: 0.5, // Softens the specular footprint like a small spherical emitter.
});
const sun = new DirectionalLight(scene, {
rotor: [0.2, 0, 0, 0.98],
color: [1, 0.95, 0.8],
intensity: 3,
});
const fill = new AmbientLight(scene, {
color: [0.1, 0.2, 0.4],
intensity: 0.2,
});
await Promise.all([point.ready, sun.ready, fill.ready]);
Rectangles and spots
const panel = new RectAreaLight(scene, {
position: [0, 2, 0],
width: 2,
height: 0.5,
intensity: 12,
});
const spot = new SpotLight(scene, {
position: [0, 1, 1],
innerAngle: 0.25,
outerAngle: 0.6,
range: 15,
});
The rectangle handle selects the default graph's linearly transformed cosine (ltc) path. Position, orientation, intensity, angles, and colors remain direct SAB mutations after allocation.
