光线映射
Sign in to savethumb|Cube with a simple lightmap (shown on the right). 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.

光照图（lightmap），或稱光线映射，是包含了電子游戏中面的光照信息的一种的光强数据。光照图是预先计算好的，而且用在静态目标上（static objects，在三维引擎里是区别于动态目标（dynamic object）的一种分类）。《Quake》是第一个使用光照图来加速渲染速度的電子游戏，同时这样做也可以避免地面的变形。
