<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.</p>

<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.
