- <h2>Code Example</h2>
- <code>
- class CustomSinCurve extends THREE.Curve {
- constructor( scale = 1 ) {
- super();
- this.scale = scale;
- }
- getPoint( t, optionalTarget = new THREE.Vector3() ) {
- const tx = t * 3 - 1.5;
- const ty = Math.sin( 2 * Math.PI * t );
- const tz = 0;
- return optionalTarget.set( tx, ty, tz ).multiplyScalar( this.scale );
- }
- }
- const path = new CustomSinCurve( 10 );
- const geometry = new THREE.TubeGeometry( path, 20, 2, 8, false );
- const material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
- const mesh = new THREE.Mesh( geometry, material );
- scene.add( mesh );
- </code>
- <h2>Constructor</h2>
- <h3>
- [name]([param:Curve path], [param:Integer tubularSegments], [param:Float radius], [param:Integer radialSegments], [param:Boolean closed])
- </h3>
- <p>
- path — [page:Curve] - A 3D path that inherits from the [page:Curve] base
- class. Default is a quadratic bezier curve.<br />
- tubularSegments — [page:Integer] - The number of segments that make up the
- tube. Default is `64`.<br />
- radius — [page:Float] - The radius of the tube. Default is `1`.<br />
- radialSegments — [page:Integer] - The number of segments that make up the
- cross-section. Default is `8`.<br />
- closed — [page:Boolean] Is the tube open or closed. Default is `false`.<br />
- </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.
- </p>
- <h3>[property:Array tangents]</h3>
- <p>An array of [page:Vector3] tangents</p>
- <h3>[property:Array normals]</h3>
- <p>An array of [page:Vector3] normals</p>
- <h3>[property:Array binormals]</h3>
- <p>An array of [page:Vector3] binormals</p>
