A lightmap is a data structure used in lightmapping, a form of surface caching in which the brightness of surfaces in a virtual scene is pre-calculated and stored in texture maps for later use. Lightmaps are most commonly applied to static objects in applications that use real-time 3D computer graphics, such as video games, in order to provide lighting effects such as global illumination at a relatively low computational cost.

Illumination Tutorial for Software 3D Rendering (2/2+) [c++20]
In this series we explore how to do illumination in your polygon-based texture-mapping 3D renderer. This time we focus on realistic diffuse lightmaps. We use nothing but standard C++20 (and libSDL for 2D graphics). Become a member: https://youtube.com/Bisqwit/join My links: Twitter: http

What Are Light Echoes? Using Reflections Of Light To See Even Further Back In Time
When we look outward into space, we’re looking backwards in time. That’s because light moves, at the speed of light. It takes time for the light to reach us. But it gets even stranger than that. Light can be absorbed, reflected, and re-emitted by gas and dust, giving us a second look. Th
