GPUBuffer: unmap() method

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Note: This feature is available in Web Workers.

The unmap() method of the GPUBuffer 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 ArrayBuffers created via GPUBuffer.getMappedRange() are detached.

Syntax

unmap()

Parameters

None.

Return value

None (Undefined).
