  We define a Graphics Turing Test to measure graphics performance in a similar
manner to the definition of the traditional Turing Test. To pass the test one
needs to reach a computational scale, the Graphics Turing Scale, for which
Computer Generated Imagery becomes comparatively indistinguishable from real
images while also being interactive. We derive an estimate for this
computational scale which, although large, is within reach of todays
supercomputers. We consider advantages and disadvantages of various computer
systems designed to pass the Graphics Turing Test. Finally we discuss
commercial applications from the creation of such a system, in particular
Interactive Cinema.
