Ep. 009: Real Time Graphics Explainer

We are joined by John Hoggard from the Defence Academy of the UK, in Shrivenham. John is a full time lecturer in Defence Simulation and Modelling, and teaches on a number of courses delivered to civilian and military personnel who go on to work on major simulation projects across industry, defence and the civil service. John guides us through a range of concepts, including how computers draw the virtual world, polygons and pixels, refresh rates, how graphics cards work and the difference between frame and refresh rates. John takes us through the latest developments in photo-realistic graphics, as well as the future development path for VR, Ray Tracing, mobile graphic and advanced sampling techniques.
