|
|
Helper object to visualize a [page:Plane].
|

|
<h2>Code Example</h2>
|
||
|
|
|
||
|
|
<code>
|
||
|
|
const plane = new THREE.Plane( new THREE.Vector3( 1, 1, 0.2 ), 3 );
|
||
|
|
const helper = new THREE.PlaneHelper( plane, 1, 0xffff00 );
|
||
|
|
scene.add( helper );
|
||
|
|
</code>
|
||
|
|
|
||
|
|
|
||
|
|
<h2>Constructor</h2>
|
||
|
|
|
||
|
|
|
||
|
|
<h3>[name]( [param:Plane plane], [param:Float size], [param:Color hex] )</h3>
|
||
|
|
<p>
|
||
|
|
[page:Plane plane] -- the plane to visualize.<br />
|
||
|
|
[page:Float size] -- (optional) side length of plane helper. Default is 1.<br />
|
||
|
|
[page:Color color] -- (optional) the color of the helper. Default is 0xffff00.<br /><br />
|
||
|
|
|
||
|
|
Creates a new wireframe representation of the passed plane.
|
||
|
|

|
||
|
|
|
||
|
|
<h2>Properties</h2>
|
||
|
|
<p>See the base [page:Line] class for common properties.</p>
|
||
|
|
|
||
|
|
<h3>[property:Plane plane]</h3>
|
||
|
|
<p>The [page:Plane plane] being visualized.</p>
|
||
|
|
|
||
|
|
<h3>[property:Float size]</h3>
|
||
|
|
<p>The side lengths of plane helper.</p>
|
||
|
|
|
||
|
|
|
||
|
|
<h2>Methods</h2>
|
||
|
|
<p>See the base [page:LineSegments] class for common methods.</p>
|
||
|
|
|
||
|
|
<h3>[method:undefined updateMatrixWorld]( [param:Boolean force] )</h3>
|
||
|
|
<p>
|
||
|
|
This overrides the method in the base [page:Object3D] class so that it also
|
||
|
|
updates the helper object according to the [page:PlaneHelper.plane .plane] and
|
||
|
|
[page:PlaneHelper.size .size] properties.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[method:undefined dispose]()</h3>
|
||
|
|
<p>
|
||
|
|
Frees the GPU-related resources allocated by this instance. Call this method whenever this instance is no longer used in your app.
