UePointLight

A light that gets emitted from a single point in all directions. This can be used to simulate light emitted from a light bulb.

This light can cast shadows - see UePointLightShadow page for details.

Code Example

var light = new UePointLight(0xffffff, 1, 100);
vec3_set(light.position, 50, 50, 50);
scene.add(light);

Constructor

UePointLight(color, intensity, distance, decay, data)

Constructs a new point light.

• color: The light's color (hex or [r, g, b]). Default is c_white.
• intensity: The light's strength/intensity. Default is 1.
• distance: Maximum range of the light. Default is 0 (no limit).
• decay: The amount the light dims along the distance of the light. Default is 2.
• data: Optional configuration object.

Properties

See the base UeLight class for common properties.

.isPointLight (readonly)

Used to check whether this or derived classes are point lights. Default is true.

.distance

If non-zero, the light's intensity will also attenuate linearly from this distance. Default is 0.

.decay

The amount the light dims along the distance of the light. Default is 2.

.shadow

A UePointLightShadow used to calculate shadows for this light.

.power

The light's power measured in lumens. Changing the power will also change the light's intensity.

Methods

See the base UeLight class for common methods.

.getPower()

Returns the light's power.

.setPower(power)

Sets the light's power.

.setDistance(distance)

Sets the maximum range of the light.

.setDecay(decay)

Sets the amount the light dims along the distance of the light.
