"Interleaved" means that multiple attributes, possibly of different types, (e.g., position, normal, uv, color) are packed into a single array buffer.

<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.
|
||
|

<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.<br />
|
||
|
|
- [page:Number offset]: Default is `0`.<br />
|
||
|
|
- [page:Number count]: Default is `-1`.<br />
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[property:String uuid]</h3>
|
||
|
|
<p>
|
||
|
|
[link:http://en.wikipedia.org/wiki/Universally_unique_identifier UUID] of this instance. This gets automatically assigned, so this shouldn't be edited.
|
||
|
|
</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]().
