Defines an arbitrary 2d shape plane using paths with optional holes. It can be used with [page:ExtrudeGeometry],
|

[page:ShapeGeometry], to get points, or to get triangulated faces.

<h2>Code Example</h2>
|
||
|
|
|
||
|
|
<code>
|
||
|
|
const heartShape = new THREE.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 geometry = new THREE.ExtrudeGeometry( heartShape, extrudeSettings );
|

const mesh = new THREE.Mesh( geometry, new THREE.MeshPhongMaterial() );

<h2>Constructor</h2>
|
||
|
|
|
||
|
|
|
||
|
|
<h3>[name]( [param:Array points] )</h3>
|
||
|
|
<p>
|
||
|
|
points -- (optional) array of [page:Vector2 Vector2s].<br /><br />
|
||
|
|
|
||
|
|
Creates a Shape from the points. The first point defines the offset, then successive points
|
||
|
|
are added to the [page:CurvePath.curves curves] array as [page:LineCurve LineCurves].<br /><br />
|
||
|
|
|
||
|
|
If no points are specified, an empty shape is created and the [page:.currentPoint] is set to
|
||
|
|
the origin.

<h2>Properties</h2>
|
||
|
|
<p>See the base [page:Path] class for common properties.</p>
|
||
|
|
|
||
|
|
<h3>[property:String uuid]</h3>
|
||
|
|
<p>
|
||
|
|
[link:http://en.wikipedia.org/wiki/Universally_unique_identifier UUID] of this instance. This gets automatically assigned, so this shouldn't be edited.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Array holes]</h3>
|
||
|
|
<p>An array of [page:Path paths] that define the holes in the shape.</p>
|
||
|
|
|
||
|
|
<h2>Methods</h2>
|
||
|
|
<p>See the base [page:Path] class for common methods.</p>
|
||
|
|
|
||
|
|
<h3>[method:Array extractPoints]( [param:Integer divisions] )</h3>
|
||
|
|
<p>
|
||
|
|

|
||
|
|
|
||
|
|
Call [page:Curve.getPoints getPoints] on the shape and the [page:.holes] array, and return an object of the form:
|
||
|
|
<code>
|
||
|
|
{
|
||
|
|
shape
|
||
|
|
holes
|

|
|
}
|
||
|

</code>
|
||
|
|
where shape and holes are arrays of [page:Vector2 Vector2s].
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[method:Array getPointsHoles]( [param:Integer divisions] )</h3>
|
||
|
|
<p>
|
||
|
|

|
||
|
|
|
||
|
|
Get an array of [page:Vector2 Vector2s] that represent the holes in the shape.
