Ray tracing will be unavoidable in 2020

Ray tracing has been used in games for some time, but as baked in images. Ray tracing, even at 30 fps, is a computational challenge that has befuddled and frustrated hardware and software engineers for decades. With clever algorithms, Moore’s Law, and dogged perseverance, computer graphics companies have pushed the envelope further every year, with 2018 marking the breakout year that Nvidia and Adshir demonstrated real-time ray tracing—RTRT, in a PC or mobile device—something we didn’t expect to see for several more years. RTRT has been demonstrated before by Intel in the days it was pursuing its Larrabee project, but
