|
||
|
|
<p>
|
||
|
|
[page:Integer skyColor] - (optional) hexadecimal color of the sky. Default is 0xffffff.<br />
|
||
|
|
[page:Integer groundColor] - (optional) hexadecimal color of the ground. Default is 0xffffff.<br />
|
||

||
|
|
|
||
|
|
<h3>[property:Float color]</h3>
|
||
|
|
<p>
|
||
|
|
The light's sky color, as passed in the constructor.
|
||
|
|
Default is a new [page:Color] set to white (0xffffff).

||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Float groundColor]</h3>
|
||
|
|
<p>
|
||
|
|
The light's ground color, as passed in the constructor.
|
||
|
|
Default is a new [page:Color] set to white (0xffffff).
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Boolean isHemisphereLight]</h3>
|
||
|

<p>
|
||
|
|
This is set equal to [page:Object3D.DefaultUp] (0, 1, 0), so that the light shines from the top down.
