AdvancedThe buffer can be used as the destination of a copy or write operation. (Examples: as the destination argument of a copyBufferToBuffer() or copyTextureToBuffer() call, or as the target of a writeBuffer() call.)
The buffer can be used as the source of a copy operation. (Examples: as the source argument of a copyBufferToBuffer() or copyBufferToTexture() call.)
The buffer can be used as an index buffer. (Example: passed to setIndexBuffer().)
The buffer can be used as to store indirect command arguments. (Examples: as the indirectBuffer argument of a drawIndirect() or dispatchWorkgroupsIndirect() call.)
The buffer can be mapped for reading. (Example: calling mapAsync() with GPUMapMode.READ) May only be combined with COPY_DST.
The buffer can be mapped for writing. (Example: calling mapAsync() with GPUMapMode.WRITE) May only be combined with COPY_SRC.
The buffer can be used to capture query results. (Example: as the destination argument of a resolveQuerySet() call.)
the buffer will not be updated frequently
The buffer can be used as a storage buffer. (Example: as a bind group entry for a GPUBufferBindingLayout with a buffer.type of "storage" or "read-only-storage".)
The buffer can be used as a uniform buffer. (Example: as a bind group entry for a GPUBufferBindingLayout with a buffer.type of "uniform".)
The buffer can be used as a vertex buffer. (Example: passed to setVertexBuffer().)
Buffer usage flags. they can be combined using the bitwise OR operator eg : BufferUsage.VERTEX | BufferUsage.INDEX
