LatheGeometry

Creates meshes with axial symmetry like vases. The lathe rotates around the Y axis.

Code Example


    const points = [];
    for (let i = 0; i < 10; i++) {
      points.push(new v3d.Vector2(Math.sin(i * 0.2) * 10 + 5, (i - 5) * 2));
    }
    const geometry = new v3d.LatheGeometry(points);
    const material = new v3d.MeshBasicMaterial({ color: 0xffff00 });
    const lathe = new v3d.Mesh(geometry, material);
    scene.add(lathe);

Constructor

LatheGeometry(points : Array, segments : Integer, phiStart : Float, phiLength : Float)

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.
segments — the number of circumference segments to generate. Default is 12.
phiStart — the starting angle in radians. Default is 0.
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.

This creates a LatheGeometry based on the parameters.

Properties

See the base BufferGeometry class for common properties.

# .parameters : Object

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

Methods
