<h2>Code Example</h2>
|
||
|
|
|
||
|
|
<code>
|
||
|
|
const points = [];
|
||
|
|
for ( let i = 0; i < 10; i ++ ) {
|
||
|
|
points.push( new THREE.Vector2( Math.sin( i * 0.2 ) * 10 + 5, ( i - 5 ) * 2 ) );
|
||
|
|
}
|
||
|
|
const geometry = new THREE.LatheGeometry( points );
|
||
|
|
const material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );
|
||
|
|
const lathe = new THREE.Mesh( geometry, material );
|
||
|
|
scene.add( lathe );
|

</code>

<h2>Constructor</h2>
|
||
|
|
|
||
|
|
<h3>[name]([param:Array points], [param:Integer segments], [param:Float phiStart], [param:Float phiLength])</h3>
|
||
|
|
<p>
|
||
|
|
points — Array of Vector2s. The x-coordinate of each point must be greater than zero. Default is an array with (0,-0.5), (0.5,0) and (0,0.5) which creates a simple diamond shape.<br />
|
||
|
|
segments — the number of circumference segments to generate. Default is 12.<br />
|
||
|
|
phiStart — the starting angle in radians. Default is 0.<br />
|
||
|
|
phiLength — the radian (0 to 2PI) range of the lathed section 2PI is a closed lathe, less than 2PI is a portion. Default is 2PI.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
This creates a [name] based on the parameters.

<h2>Properties</h2>
|
||
|
|
<p>See the base [page:BufferGeometry] class for common properties.</p>

|
|
<h3>[property:Object parameters]</h3>
|
||
|
|
<p>
|
||
|
|
An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.
