TV and Movies have a ton of Computer Generated Images [CGI] to create fantasy worlds with dragons and castles, futuristic intergalactic civilizations, or historically accurate cities of 1700s Japan, such as in the recent TV show Shogun. But have you ever wondered how these CGI / Computer Generated Images are made? And how are these scenes so accurate that they fool the eye into thinking they are real. In this video, we're diving into Path Tracing, a type of Ray Tracing algorithm. We'll explore exactly how Ray Tracing is used to create accurate lighting and realistic scenes and how it uses quadrillions of calculations. We're working on more ambitious subjects like computer architecture and graphics cards. Any contribution would greatly help make these videos. https://www.patreon.com/brancheducation Branch Education Website: https://www.branch.education Branch Education Facebook: https://www.facebook.com/BranchEducation/ Thank you to Cem Yuksel, a professor at the School of Computer at the University of Utah. He helped to proofread the script for inaccuracies, and his only course on computer graphics and interactive graphics was incredibly useful in researching this video.
