<h1>立方缓冲几何体（[name]）</h1>

<p class="desc">[name]是四边形的原始几何类，它通常使用构造函数所提供的“width”、“height”、“depth”参数来创建立方体或者不规则四边形。</p>

<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>
