[name]

Creates a tube that extrudes along a 3d curve.

Code Example


		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 );

Constructor

[name]([param:Curve path], [param:Integer tubularSegments], [param:Float radius], [param:Integer radialSegments], [param:Boolean closed])

path — [page:Curve] - A 3D path that inherits from the [page:Curve] base class. Default is a quadratic bezier curve.
tubularSegments — [page:Integer] - The number of segments that make up the tube. Default is `64`.
radius — [page:Float] - The radius of the tube. Default is `1`.
radialSegments — [page:Integer] - The number of segments that make up the cross-section. Default is `8`.
closed — [page:Boolean] Is the tube open or closed. Default is `false`.

Properties

See the base [page:BufferGeometry] class for common properties.

[property:Object parameters]

An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.

[property:Array tangents]

An array of [page:Vector3] tangents

[property:Array normals]

An array of [page:Vector3] normals

[property:Array binormals]

An array of [page:Vector3] binormals

Methods

See the base [page:BufferGeometry] class for common methods.
