The unmap()
method of the

interface unmaps the mapped range of the GPUBuffer
, making its contents available for use by the GPU again after it has previously been mapped with GPUBuffer.mapAsync()
(the GPU cannot access a mapped GPUBuffer
).
When unmap()
is called, any ArrayBuffer
s created via GPUBuffer.getMappedRange()
are detached.
