<code>
|
||
|
|
const geometry = new THREE.BoxGeometry( 1, 1, 1 );
|
||
|
|
const material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );
|
||
|
|
const mesh = new THREE.Mesh( geometry, material );
|

|
|
<p>
|
||
|
|
[page:BufferGeometry geometry] —— （可选）[page:BufferGeometry]的实例，默认值是一个新的[page:BufferGeometry]。<br />

||
|
|
<h3>[property:BufferGeometry geometry]</h3>
|
||
|
|
<p>
|
||
|
|
[page:BufferGeometry] 的实例或者派生类，定义了物体的结构。
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Boolean isMesh]</h3>
|
||
|

||
|
|
Read-only flag to check if a given object is of type [name].
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:Material material]</h3>
|
||
|
|
<p>
|
||
|
|

<p>
|
||
|
|
一个包含有权重（值一般在0-1范围内）的数组，指定应用了多少变形。
|
||
|
|
默认情况下是未定义的，但是会被[page:Mesh.updateMorphTargets updateMorphTargets]重置为一个空数组。
|
||
|
|
</p>

<h3>[property:Object morphTargetDictionary]</h3>
|
||
|
|
<p>
|
||
|
|
基于morphTarget.name属性的morphTargets字典。
|
||
|
|

||
|
|
|
||
|
|
<h3>[method:Mesh clone]()</h3>
|
||
|
|
<p>返回这个[name]对象及其子级的克隆。</p>

|
||
|
|
<h3>[method:undefined raycast]( [param:Raycaster raycaster], [param:Array intersects] )</h3>
|
||
|
|
<p>
|
||
|
|
在一条投射出去的[page:Ray]（射线）和这个网格之间产生交互。
|
