<div class="desc">Class for generating meshes with axial symmetry. Possible uses include donuts, pipes, vases etc. The lathe rotate around the Z axis.</div>

<h2>Example</h2>
|
||
|
|
|
||
|
|
<code>
|
||
|
|
var points = [];
|
||
|
|
for ( var i = 0; i < 10; i ++ ) {
|
||
|
|
points.push( new THREE.Vector3( Math.sin( i * 0.2 ) * 15 + 50, 0, ( 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]([page:Array points], [page:Integer segments], [page:Float phiStart], [page:Float phiLength])</h3>
|
||
|
|
<div>
|
||
|
|
points — Array of Vector3s. Since this rotates around Z axis, the y-values can be set to 0<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 2*PI) range of the lathed section 2*PI is a closed lathe, less than 2PI is a portion. Default is 2*PI
|
||
|
|
</div>
|
||
|
|
<div>
|
||
|
|
This creates a LatheGeometry based on the parameters.
|
||
|
|
</div>
