<h2>代码示例</h2>
|
|||
|
|
|
|||
|
|
<code>const geometry = new THREE.BoxGeometry( 1, 1, 1 );
|
|||
|
|
const material = new THREE.MeshBasicMaterial( {color: 0x00ff00} );
|
|||
|
|
const cube = new THREE.Mesh( geometry, material );
|
|||
|
|
scene.add( cube );
|
|||
|
|
</code>
|
|||
|
|
|
|||
|
|
<h2>构造器</h2>
|
|||
|
|
|
|||
|
|
<h3>[name]([param:Float width], [param:Float height], [param:Float depth], [param:Integer widthSegments], [param:Integer heightSegments], [param:Integer depthSegments])</h3>
|
|||
|
|
<p>
|
|||
|
|
width — X轴上面的宽度，默认值为1。<br />
|
|||
|
|
height — Y轴上面的高度，默认值为1。<br />
|
|||
|
|
depth — Z轴上面的深度，默认值为1。<br />
|
|||
|
|
widthSegments — （可选）宽度的分段数，默认值是1。<br />
|
|||
|
|
heightSegments — （可选）宽度的分段数，默认值是1。<br />
|
|||
|
|
depthSegments — （可选）宽度的分段数，默认值是1。
|
|||
|
|
</p>

<h2>属性</h2>
|
|||
|
|
<p>共有属性请参见其基类[page:BufferGeometry]。</p>
|
|||
|
|
|
|||
|
|
<h3>[property:Object parameters]</h3>
|
|||
|
|
<p>
|
|||
|
|
一个包含着构造函数中每个参数的对象。在对象实例化之后，对该属性的任何修改都不会改变这个几何体。
|
|||
|
|
</p>
|
|||
|
|
<p>
|
|||
|
|
使用上面的示例代码来作为基础：
|
|||
|
|
<code>
|
|||
|
|
geometry.parameters; // outputs an object {width: 1, height: 1, depth: 1, widthSegments: undefined, heightSegments: undefined}
|
|||
|
|
cube.geometry.parameters; // as above
|
|||
|
|
cube.geometry.parameters.width; // === 1
|
|||
|
|
cube.geometry.parameters.widthSegments // === undefined.
|
|||
|
|
</code>
|
|||
|
|
</p>
