<h2>Code Example</h2>
|
||
|
|
|
||
|
|
<code>
|
||
|
|
const material = new THREE.LineBasicMaterial({
|
||
|
|
color: 0x0000ff
|
||
|
|
});
|
||
|
|
|
||
|
|
const points = [];
|

points.push( new THREE.Vector3( - 10, 0, 0 ) );
|

points.push( new THREE.Vector3( 0, 10, 0 ) );
|

|
|
const geometry = new THREE.BufferGeometry().setFromPoints( points );
|

<h2>Constructor</h2>
|
||
|
|
|
||
|
|
<h3>[name]( [param:BufferGeometry geometry], [param:Material material] )</h3>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
[page:BufferGeometry geometry] — vertices representing the line segment(s). Default is a new [page:BufferGeometry].<br />
|
||
|
|
[page:Material material] — material for the line. Default is a new [page:LineBasicMaterial].<br />
|
||
|
|
</p>
|

|
|
|
||
|
|
<h2>Properties</h2>
|
||
|
|
<p>See the base [page:Object3D] class for common properties.</p>
|
||
|
|
|
||
|
|
|
||
|
|
<h3>[property:BufferGeometry geometry]</h3>
|
||
|
|
<p>Vertices representing the line segment(s).</p>
|
||
|
|
|
||
|
|
<h3>[property:Boolean isLine]</h3>
|
||
|
|
<p>
|
||
|
|
Read-only flag to check if a given object is of type [name].
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Material material]</h3>
|
||
|
|
<p>Material for the line.</p>
|
||
|
|
|
||
|
|
<h3>[property:Array morphTargetInfluences]</h3>
|
||
|
|
<p>
|
||
|
|
An array of weights typically from 0-1 that specify how much of the morph is applied.
|
||
|
|
Undefined by default, but reset to a blank array by [page:.updateMorphTargets]().
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Object morphTargetDictionary]</h3>
|
||
|
|
<p>
|
||
|
|
A dictionary of morphTargets based on the morphTarget.name property.
|
||
|
|
Undefined by default, but rebuilt [page:.updateMorphTargets]().

||
|
|
</p>

<h2>Methods</h2>
|
||
|
|
<p>See the base [page:Object3D] class for common methods.</p>
|
||
|
|
|
||
|
|
<h3>[method:this computeLineDistances]()</h3>
|
||
|
|
<p>
|
||
|
|
Computes an array of distance values which are necessary for [page:LineDashedMaterial]. For each vertex in the geometry, the method calculates the cumulative length from the current point to the very beginning of the line.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[method:undefined raycast]( [param:Raycaster raycaster], [param:Array intersects] )</h3>
|
||
|
|
<p>
|
||
|
|
Get intersections between a casted [page:Ray] and this Line.
|
||
|
|
[page:Raycaster.intersectObject] will call this method.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[method:Line clone]()</h3>
|
||
|
|
<p>
|
||
|
|
Returns a clone of this Line object and its descendants.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[method:undefined updateMorphTargets]()</h3>
|
||
|
|
<p>
|
||
|
|
Updates the morphTargets to have no influence on the object. Resets the
|
||
|
|
[page:.morphTargetInfluences] and [page:.morphTargetDictionary] properties.
|
||
|
|
