UeHemisphereLight

A light source positioned directly above the scene, with color fading from the sky color to the ground color.

The light's direction is determined by its position relative to the origin (0, 0, 0). By default, the position is (0, 0, 100), meaning the light comes from above (along the Z axis).

This light cannot be used to cast shadows.

Code Example

var light = new UeHemisphereLight(0xffffbb, 0x080820, 1);
vec3_set(light.position, 0, 0, 100);
scene.add(light);

Constructor

UeHemisphereLight(skyColor, groundColor, intensity, data)

Constructs a new hemisphere light.

• skyColor: The light's sky color (hex or [r, g, b]). Default is c_white.
• groundColor: The light's ground color (hex or [r, g, b]). Default is c_white.
• intensity: The light's strength/intensity. Default is 1.
• data: Optional configuration object.

Properties

.skyColor

The light's sky color as an array [r, g, b].

.groundColor

The light's ground color as an array [r, g, b].

.intensity

The light's strength/intensity.

.position

The light's position. The vector from (0, 0, 0) to this position defines the direction of the sky color.

.isHemisphereLight (readonly)

This flag can be used for type testing. Default is true.

Methods

.setSkyColor(color)

Sets the sky color. Accepts hex color or [r, g, b] array.

.setGroundColor(color)

Sets the ground color. Accepts hex color or [r, g, b] array.
