Constructor

.new Lathe(paramsopt)

A LatheGeometry allows you to create shapes from a smooth curve. This curve is defined by a number of points (also called knots) and is most often called a spline. This spline is rotated around a fixed point and results in vase- and bell-like shapes.

In 3D computer graphics, a lathed object is a 3D model whose vertex geometry is produced by rotating the points of a spline or other point set around a fixed axis. The lathing may be partial; the amount of rotation is not necessarily a full 360 degrees. The point set providing the initial source data can be thought of as a cross section through the object along a plane containing its axis of radial symmetry.

The following example shows a geometry which can be generated using Lathe class.

Example

Creating a Lath, and adding to app

const points = [];

for (let i = 0; i < 10; i++) {
  points.push(
    new THREE.Vector2(
      (Math.sin(i * 0.7) * 15 + 50) / 10,
      (i - 5) * 0.2
    )
  );
}

const lathe = new Lathe({
  geometry: {
    points: points
  },

  material: new THREE.MeshBasicMaterial({
    color: 0xffffff
  }),

  position: [0, 50, 10]
}).addTo(app);
