"交叉存储" 表明多个类型的 attributes （例如，顶点位置、法向量、UV 和颜色值）被存储到一个队列中。
|
|
<br/><br/>
|
|
如下链接有对交叉存储更详细的介绍: [link:https://blog.tojicode.com/2011/05/interleaved-array-basics.html Interleaved array basics]

<h2>例子</h2>
|
|
|
|
<p>[example:webgl_buffergeometry_points_interleaved webgl / buffergeometry / points / interleaved]</p>
|
|
|
|
<h2>构造函数</h2>
|
|
<h3>[name]( [param:TypedArray array], [param:Integer stride] )</h3>
|
|
<p>
|
|
[page:TypedArray array] -- 一个基于共享缓存的类型化队列。该队列存储几何体相关数据。<br/>
|
|
[page:Integer stride] -- 每个顶点占用类型化队列的多少个元素。
|
|
</p>
|
|
|
|
<h2>属性</h2>
|
|
|
|
<h3>[property:Array array]</h3>
|
|
<p>
|
|
一个基于共享缓存的类型化队列。该队列存储几何体相关数据。
|
|
</p>
|
|
|
|
<h3>[property:Integer stride]</h3>
|
|
<p>
|
|
每个顶点占用类型化队列的多少个元素。
|
|
</p>
|
|
|
|
<h3>[property:Integer count]</h3>
|
|
<p>
|
|
类型化队列中，所有元素的数目。
|
|
</p>
|
|
|
|
<h3>[property:Object updateRange]</h3>
|
|
<p>
|
|
对象存储着需要更新的数据的偏移量和数量。<br />
|
|
- [page:Number offset]: 默认值为 *0*。<br />
|
|
- [page:Number count]: 默认值为 *-1*。<br />
|
|
</p>
|
|
|
|
<h3>[property:String uuid]</h3>
|
|
<p>
|
|
该类所创建的实例的[link:http://en.wikipedia.org/wiki/Universally_unique_identifier UUID]。它是自动被指定的，因此它不应当被编辑、更改。
|
|
</p>
|
|
|
|
<h3>[property:Integer version]</h3>
|
|
<p>
|
|
版本号，每次 needsUpdate 属性设置为 true 时，版本号增加。
|
|
</p>
|
|
|
|
<h3>[property:Integer needsUpdate]</h3>
|
|
<p>
|
|
默认值为 *false*。该值被设置为 true 时，会导致 [page:InterleavedBuffer.version version] 增加。
|
|
</p>
|
|
|
|
<h3>[property:Usage usage]</h3>
|
|
<p>
|
|
Defines the intended usage pattern of the data store for optimization purposes. Corresponds to the *usage* parameter of
|
|
[link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/bufferData WebGLRenderingContext.bufferData]().

<h2>方法</h2>
|
|
|
|
<h3>[method:this copy]( [param:InterleavedBuffer source] ) </h3>
|
|
<p>
|
|
将参数指定的 [name] 拷贝到当前 [name]。
|
|
</p>
|
|
|
|
<h3>[method:this copyAt]( [param:Integer index1], [param:InterleavedBuffer attribute], [param:Integer index2] ) </h3>
|
|
<p> 将数据从 attribute[index2] 拷贝到 [page:InterleavedBuffer.array array][index1]。</p>
|
|
|
|
<h3>[method:this set]( [param:TypedArray value], [param:Integer offset] ) </h3>
|
|
<p>
|
|
value - 被拷贝的源（类型化）队列。<br/>
|
|
offset - 源队列中，数据开始拷贝的偏移量。默认值是 *0*.<br/><br />
|
|
|
|
将源队列数据拷贝到目标队列缓存中。
|
|
</p>
|
|
|
|
<h3>[method:InterleavedBuffer clone]( [param:Object data] ) </h3>
|
|
<p>
|
|
data - This object holds shared array buffers required for properly cloning geometries with interleaved attributes.<br/><br />
|
|
|
|
Creates a clone of this [name].
|
|
</p>
|
|
|
|
<h3>[method:this setUsage] ( [param:Usage value] ) </h3>
|
|
<p>Set [page:InterleavedBuffer.usage usage] to value.</p>
|
|
|
|
<h3>[method:Object toJSON]( [param:Object data] ) </h3>
|
|
<p>
|
|
data - This object holds shared array buffers required for properly serializing geometries with interleaved attributes.<br/><br />
|
|
|
|
Serializes this [name].
