Gamers - Working on How Lighting Works to Make Better Game Graphics - Prove the Apollo 11 Moon Landing Conspiracy Theorists Wrong

Modeling how light hits objects - and reflects - is one of the most difficult problem in gaming graphics.

In creating digital environments for game players, naturalistic indirect lighting - based on reflections off objects in the environment - is a key part of making scenes that don't look harsh or artificial. This technique - known as global illumination - used to require too much computational power to render in real time.

Then in 2011, NVIDIA engineers developed and demonstrated a new approach to computing global illumination dynamically in real time.

Now, as seen in the video above and described in a Sept. 18th, 2014 endgadget article, the latest iteration of dynamic global illumination technology - known as VXGI - has been used to show how images taken on the moon's surface were illuminated from a single primary light source - the sun -  and reflections off items known to be on the moon, e.g., the moon's surface, the lunar module itself, and Neil Armstrong's highly reflective spacesuit.
