<h2>Example</h2>
|
|
<code>areaLight1 = new THREE.AreaLight( 0xffffff, 1 );
|
|
areaLight1.position.set( 0.0001, 10.0001, -18.5001 );
|
|
areaLight1.rotation.set( -0.74719, 0.0001, 0.0001 );
|
|
areaLight1.width = 10;
|
|
areaLight1.height = 1;
|
|
|
|
scene.add( areaLight1 );</code>

<h2>Constructor</h2>
|
|
|
|
|
|
<h3>[name]( [page:Integer hex], [page:Float intensity])</h3>
|
|
<div>
|
|
[page:Integer hex] — Numeric value of the RGB component of the color.<br />
|
|
[page:Float intensity] — Numeric value of the light's strength/intensity.
|
|
</div>
|
|
<div>
|
|
This creates a arealight with color.
|
|
</div>

<h2>Properties</h2>
|
|
|
|
|
|
|
|
<h3>[property:Vector3 right]</h3>
|
|
<div>
|
|
Sets or gets an unit vector that indicates the right side of the light. This is calculated in local space.
|
|
</div>
|
|
|
|
<h3>[property:Vector3 normal]</h3>
|
|
<div>
|
|
Sets or gets an unit vectorSets or gets an unit vector that indicates the right side of the light. This is calculated in local space.
|
|
</div>
|
|
|
|
<h3>[property:number height]</h3>
|
|
<div>
|
|
Sets or gets the height of the illuminating plane.
|
|
</div>
|
|
|
|
<h3>[property:number width]</h3>
|
|
<div>
|
|
Sets or gets the width of the illuminating plane.
|
|
</div>
|
|
|
|
<h3>[property:Float intensity]</h3>
|
|
<div>
|
|
Light's intensity.<br />
|
|
Default — *1.0*.
|
|
</div>
|
|
|
|
<h3>[property:number constantAttenuation]</h3>
|
|
<div>
|
|
Sets or gets the attention of the light in constant space. This is independant of the distance of the light.
|
|
</div>
|
|
|
|
<h3>[property:number linearAttenuation]</h3>
|
|
<div>
|
|
Sets or gets the attention of the light in linear space. This increases the attenuation linearly with the distance from the light.
|
|
</div>
|
|
|
|
<h3>[property:number quadraticAttenuation]</h3>
|
|
<div>
|
|
Sets or gets the attention of the light in linear space. This increases the attenuation quadratic with the distance from the light.
|
|
</div>
