Lightmap

A lightmap is a technique used in computer graphics, particularly in the context of 3D rendering and game development, to pre-calculate lighting effects for static objects in a scene. Lightmaps store the indirect lighting information of surfaces in a texture, allowing for more efficient rendering during real-time applications. Here's a breakdown of how lightmaps work: 1. **Pre-calculation**: During the development phase, rendering software calculates how light interacts with surfaces in a scene.
