Creates a tube that extrudes along a 3D curve.
class CustomSinCurve extends v3d.Curve {
constructor(scale = 1) {
super();
this.scale = scale;
}
getPoint(t, optionalTarget = new v3d.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 v3d.TubeGeometry(path, 20, 2, 8, false);
const material = new v3d.MeshBasicMaterial({ color: 0x00ff00 });
const mesh = new v3d.Mesh(geometry, material);
app.scene.add(mesh);
path — a 3D path that inherits from the Curve base class. Default is a quadratic bezier curve.
tubularSegments — the number of segments that make up the tube. Default is 64.
radius — the radius of the tube. Default is 1.
radialSegments — the number of segments that make up the cross-section. Default is 8.
closed — is the tube open or closed. Default is false.
Procedural geometry is fun. However, in real life applications this feature is rarely needed. It would be more efficient do design tubes in the preferred modelling suite and export/load to Verge3D via glTF.
See the base BufferGeometry class for common properties.
An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.
An array of Vector3 tangents
An array of Vector3 normals
An array of Vector3 binormals
