An introduction into interleaved arrays can be found here: [link:https://blog.tojicode.com/2011/05/interleaved-array-basics.html Interleaved array basics]

A typed array with a shared buffer. Stores the geometry data.
The number of typed-array elements per vertex.
Gives the total number of elements in the array.
Default is *false*.
Object containing offset and count.
Default is *0*.
Default is *-1*.
A version number, incremented every time the needsUpdate property is set to true.
Default is *true*.
Default is *false*. Setting this to true increments [page:InterleavedBuffer.version version].
Set [page:InterleavedBuffer.dynamic dynamic] to value.
Copies another [name] to this [name].
Copies data from attribute[index2] to [page:InterleavedBuffer.array array][index1].
value - The source (typed) array.
offset - The offset into the target array at which to begin writing values from the source array. Default is *0*.
Stores multiple values in the buffer, reading input values from a specified array.
