- <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.
