The disclosure pertains to techniques for operation of graphics systems and task execution on a graphics processor. One such technique comprises a computer-implemented method for task execution on a graphics processor, the method comprising creating a data structure for grouping data resources, populating the data structure with two or more data resources for encoding into a graphics processing language by an encoding object, passing the data structure to a first programming interface command, the first programming interface command configured to access the data structure's data resources, triggering execution of a first function on a graphics processor in response to passing the data structure to the first programming interface command, passing the data structure to a second programming interface command, the second programming interface command configured to access the data structure's data resources, and triggering execution of a second function on the graphics processor in response to passing the data structure to the second programming interface command.
