Enumeration: LightType

Defines the types of light sources available for 3D scene illumination.

Different light types simulate various real-world lighting scenarios, each with unique characteristics in how they cast light and shadows. The appropriate light type depends on the desired visual effect and the physical lighting being simulated.

Example​

// Creating a spotlight for focused illumination
const spotlight = new Light("spotlight", LightType.SPOT, scene);
spotlight.position = new Vector3(0, 5, 0);
spotlight.direction = new Vector3(0, -1, 0);
spotlight.angle = Math.PI/4; // 45 degree cone

// Adding ambient illumination with a hemispheric light
const ambientLight = new Light("ambient", LightType.HEMISPHERIC, scene);
ambientLight.intensity = 0.3;

Enumeration Members​

DIRECTIONAL​

DIRECTIONAL: "DIRECTIONAL"

Parallel light rays from a distant source, like the sun.

Directional lights cast consistent, parallel light rays across the entire scene, regardless of distance. The light's position only affects shadow direction, not intensity. Ideal for simulating sunlight, moonlight, or any light source that's extremely distant relative to the scene.

HEMISPHERIC​

HEMISPHERIC: "HEMISPHERIC"

A soft, diffuse light that illuminates from above and below.

Hemispheric lights provide gentle ambient illumination with directional variation, simulating skylight with ground reflection. These lights have a primary direction but illuminate the entire scene with soft gradients. Perfect for outdoor scenes or general ambient lighting.

POINT​

POINT: "POINT"

Light emitted equally in all directions from a single point.

Point lights radiate uniformly in all directions, similar to a light bulb or candle. Objects closer to the light receive more illumination than distant objects. Ideal for lamps, bulbs, or any omnidirectional light source.

SPOT​

SPOT: "SPOT"

A cone-shaped light emanating from a single point.

Spotlights project light in a specific direction within a defined angle, creating a cone of illumination that becomes wider with distance. Perfect for highlighting specific objects or areas, similar to stage spotlights or directional lamps.
