ExtrudeGeometry

Creates extruded geometry from a path shape.

Code Example


    const length = 12, width = 8;

    const shape = new v3d.Shape();
    shape.moveTo(0,0);
    shape.lineTo(0, width);
    shape.lineTo(length, width);
    shape.lineTo(length, 0);
    shape.lineTo(0, 0);

    const extrudeSettings = {
        steps: 2,
        depth: 16,
        bevelEnabled: true,
        bevelThickness: 1,
        bevelSize: 1,
        bevelOffset: 0,
        bevelSegments: 1
    };

    const geometry = new v3d.ExtrudeGeometry(shape, extrudeSettings);
    const material = new v3d.MeshBasicMaterial({ color: 0x00ff00 });
    const mesh = new v3d.Mesh(geometry, material) ;
    app.scene.add(mesh);

Constructor

ExtrudeGeometry(shapes : Array, options : Object)

shapes — shape or an array of shapes.
options — object that can contain the following parameters:

curveSegments — number of points on the curves. Default is 12.
steps — number of points used for subdividing segments along the depth of the extruded spline. Default is 1.
depth — depth to extrude the shape. Default is 1.
bevelEnabled — apply beveling to the shape. Default is true.
bevelThickness — how deep into the original shape the bevel goes. Default is 0.2.
bevelSize — distance from the shape outline that the bevel extends. Default is bevelThickness - 0.1.
bevelOffset — distance from the shape outline that the bevel starts. Default is 0.
bevelSegments — number of bevel layers. Default is 3.
extrudePath — a 3D spline path along which the shape should be extruded. Bevels not supported for path extrusion.
UVGenerator — object that provides UV generator functions.

This object extrudes a 2D shape to a 3D geometry.

When creating a mesh with this geometry, if you'd like to have a separate material used for its face and its extruded sides, you can use an array of materials. The first material will be applied to the face; the second material will be applied to the sides.

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

See the base BufferGeometry class for common methods.
