<h1>[name]</h1>
<p class="desc">Creates meshes with axial symmetry like vases. The lathe rotates around the Y axis.</p>
<iframe id="scene" src="scenes/geometry-browser.html#LatheGeometry"></iframe>
<script>
// iOS iframe auto-resize workaround
if ( /(iPad|iPhone|iPod)/g.test( navigator.userAgent ) ) {
var scene = document.getElementById( 'scene' );
scene.style.width = getComputedStyle( scene ).width;
scene.style.height = getComputedStyle( scene ).height;
scene.setAttribute( 'scrolling', 'no' );
}
</script>
<h2>Example</h2>
<code>
var points = [];
for ( var i = 0; i < 10; i ++ ) {
points.push( new THREE.Vector2( Math.sin( i * 0.2 ) * 10 + 5, ( i - 5 ) * 2 ) );
}
var geometry = new THREE.LatheGeometry( points );
var material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );
var 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.<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 LatheGeometry based on the parameters.
</p>
<h2>Properties</h2>
<p>See the base [page:Geometry] 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.
</p>
