Abstract
One embodiment of the invention is a method for accessing and updating data in a buffer object during the execution of a shader program. The method includes loading a plurality of data portions in the buffer object, initiating a first execution of a shader program that accesses a first portion of data in the buffer object, receiving a request to update the first portion of data in the buffer object; updating a version of the first portion of data in the buffer object to reflect the update, initiating a second execution of a shader program that accesses the updated version of the first portion of data in the buffer object, wherein the second execution of the shader program occurs without waiting for the execution of the first shader program to complete.
