The result of a query object is acquired by the application through the OpenGL API into a client provided memory location. Should the result returned by the API be required for use in a shader, it must be passed back to the GL via a program uniform or some other mechanism. This requires a round-trip from the GPU to the CPU and back. This extension introduces a mechanism whereby the result of a query object may be retrieved into a buffer object instead of client memory. This allows the query rsult to be made available to a shader without a round-trip to the CPU for example by subsequently using the buffer object as a uniform buffer, texture buffer or other data store visible to the shader. This functionality may also be used to place the results of many query objects into a single, large buffer and then map or otherwise read back the entire buffer at a later point in time, avoiding a per-query object CPU-GPU synchronization event. The extension allows acquiring the result of any query object type supported by the GL implementation into a buffer object. The implementation will determine the most efficient method of copying the query result to the buffer.
