ABSTRACT:
A system for validating the output of an updated graphics rendering engine is presented. The system includes two computer systems, with one computer system including an updated graphics rendering engine. The two computers are configured to execute test instructions that cause graphic information to be rendered on the computers. The two computers are further configured to respond to sample requests during the executing of the test instructions. Each computer responds by retrieving the currently rendered data on the computer as a rendered sample. The system also includes a master computer. The master computer is configured to retrieve the rendered samples of the two computers, compare the rendered samples to determine whether there are differences, and if there are differences, report those differences.
