Shape

Defines an arbitrary 2D shape plane using paths with optional holes. It can be used with ExtrudeGeometry, ShapeGeometry, to get points, or to get triangulated faces.

Code Example


    const heartShape = new v3d.Shape();

    heartShape.moveTo(25, 25);
    heartShape.bezierCurveTo(25, 25, 20, 0, 0, 0);
    heartShape.bezierCurveTo(-30, 0, -30, 35, -30, 35);
    heartShape.bezierCurveTo(-30, 55, -10, 77, 25, 95);
    heartShape.bezierCurveTo(60, 77, 80, 55, 80, 35);
    heartShape.bezierCurveTo(80, 35, 80, 0, 50, 0);
    heartShape.bezierCurveTo(35, 0, 25, 25, 25, 25);

    const extrudeSettings = { depth: 8, bevelEnabled: true, bevelSegments: 2, steps: 2, bevelSize: 1, bevelThickness: 1 };
    const geometry = new v3d.ExtrudeGeometry(heartShape, extrudeSettings);

    const mesh = new v3d.Mesh(geometry, new v3d.MeshLambertMaterial());

Constructor

Shape(points : Array)

points — (optional) array of Vector2s.

Creates a Shape from the points. The first point defines the offset, then successive points are added to the curves array as LineCurves.

If no points are specified, an empty shape is created and the .currentPoint is set to the origin.

Properties

See the base Path class for common properties.

# .uuid : String

UUID of this instance. This gets automatically assigned, so this shouldn't be edited.

# .holes : Array

An array of paths that define the holes in the shape.

Methods

See the base Path class for common methods.

# .extractPoints(divisions : Integer) → Array

divisions — The fineness of the result.

Call getPoints on the shape and the .holes array, and return an object of the form:


    {
        shape
        holes
    }

where shape and holes are arrays of Vector2s.

# .getPointsHoles(divisions : Integer) → Array

divisions — The fineness of the result.

Get an array of Vector2s that represent the holes in the shape.
