<h3>[name]([param:Array shapes], [param:Object options])</h3>
|
||
|
|
<p>
|
||
|
|
shapes — Shape or an array of shapes. <br />
|
||
|
|
options — Object that can contain the following parameters.
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>curveSegments — int. Number of points on the curves. Default is 12.</li>
|
||
|
|
<li>steps — int. Number of points used for subdividing segments along the depth of the extruded spline. Default is 1.</li>
|
||
|
|
<li>depth — float. Depth to extrude the shape. Default is 1.</li>
|
||
|
|
<li>bevelEnabled — bool. Apply beveling to the shape. Default is true.</li>
|
||
|
|
<li>bevelThickness — float. How deep into the original shape the bevel goes. Default is 0.2.</li>
|
||
|
|
<li>bevelSize — float. Distance from the shape outline that the bevel extends. Default is bevelThickness - 0.1.</li>
|
||
|
|
<li>bevelOffset — float. Distance from the shape outline that the bevel starts. Default is 0.</li>
|
||
|
|
<li>bevelSegments — int. Number of bevel layers. Default is 3.</li>
|
||
|
|
<li>extrudePath — THREE.Curve. A 3D spline path along which the shape should be extruded. Bevels not supported for path extrusion.</li>
|
||
|
|
<li>UVGenerator — Object. object that provides UV generator functions</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
This object extrudes a 2D shape to a 3D geometry.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
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.
|
||
|
|

<h2>Properties</h2>
|
||
|
|
<p>See the base [page:BufferGeometry] class for common properties.</p>
|
||
|
|
|
||
|
|
<h3>[property:Object parameters]</h3>
|
||
|
|
<p>
|
||
|
|
An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.
|
