Most of what happens within the video games we play is invisible to us. Even the elements we’re looking straight at work because of what’s happening behind the scenes. If you’ve ever watched a behind-the-scenes video about game development, you might’ve seen these versions of flat, gray game worlds filled with lines and icons pointing every which way, with multiple grids and layers. These are the visual representations of all the systems that make the game work.

This is an especially weird dichotomy to consider when it comes to lighting in any game with a 3D perspective, but especially so in high-fidelity games. We don’t see light so much as we see everything it touches; it’s invisible, but it gives us most of our information about game worlds. And it’s a lot more complex than “turn on lamp, room light up.” Reflection, absorption, diffusion, subsurface scattering–the movement of light is a complex thing that has been explored by physicists in the real world for literally centuries, and will likely be studied for centuries more. In the middle of all of that are game designers, applying the science of light to video games in practical ways, balanced with the limitations
