<h1>[name]</h1>
<p class="desc">
"Interleaved" means that multiple attributes, possibly of different types, (e.g., position, normal, uv, color) are packed into a single array buffer.
<br/><br/>
An introduction into interleaved arrays can be found here: [link:https://blog.tojicode.com/2011/05/interleaved-array-basics.html Interleaved array basics]
</p>
<h2>Example</h2>
<p>[example:webgl_buffergeometry_points_interleaved webgl / buffergeometry / points / interleaved]</p>
<h2>Constructor</h2>
<h3>[name]( [param:TypedArray array], [param:Integer stride] )</h3>
<p>
[page:TypedArray array] -- A typed array with a shared buffer. Stores the geometry data.<br/>
[page:Integer stride] -- The number of typed-array elements per vertex.
</p>
<h2>Properties</h2>
<h3>[property:Array array]</h3>
<p>
A typed array with a shared buffer. Stores the geometry data.
</p>
<h3>[property:Integer stride]</h3>
<p>
The number of typed-array elements per vertex.
</p>
<h3>[property:Integer count]</h3>
<p>
Gives the total number of elements in the array.
</p>
<h3>[property:Object updateRange]</h3>
<p>
Object containing offset and count.
</p>
<h3>[property:Number updateRange.offset]</h3>
<p>
Default is *0*.
</p>
<h3>[property:Number updateRange.count]</h3>
<p>
Default is *-1*.
</p>
<h3>[property:Integer version]</h3>
<p>
A version number, incremented every time the needsUpdate property is set to true.
</p>
<h3>[property:Boolean needsUpdate]</h3>
<p>
Default is *false*. Setting this to true increments [page:InterleavedBuffer.version version].
</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]().
</p>
<h2>Methods</h2>
<h3>[method:InterleavedBuffer copy]( [param:InterleavedBuffer source] ) </h3>
<p>
Copies another [name] to this [name].
</p>
<h3>[method:InterleavedBuffer copyAt]( [param:Integer index1], [param:InterleavedBuffer attribute], [param:Integer index2] ) </h3>
<p>Copies data from attribute[index2] to [page:InterleavedBuffer.array array][index1].</p>
<h3>[method:InterleavedBuffer set]( [param:TypedArray value], [param:Integer offset] ) </h3>
<p>
value - The source (typed) array.<br/>
offset - The offset into the target array at which to begin writing values from the source array. Default is *0*.<br/><br />
Stores multiple values in the buffer, reading input values from a specified array.
</p>
<h3>[method:InterleavedBuffer clone]() </h3>
<p>
Creates a clone of this [name].
</p>
<h3>[method:BufferAttribute setUsage] ( [param:Usage value] ) </h3>
<p>Set [page:BufferAttribute.usage usage] to value.</p>
