【更新】Local Global Illumination 1.1.0全局照明
What it does
LGI simulates global illumination. Global illumination is the way that light bounces around in the real world. LGI can add realistic diffuse lighting to scenes.
How it works
Local Global Illumination (LGI) uses a reflection probe to constantly re-render the local scene area. This means that LGI creates a map of the light in the area around the camera.
LGI then uses lighting algorithms to convert that map into a diffuse irradiance map. A diffuse irradiance map is a map that shows how much light is coming from different directions.
Finally, LGI uses post-processing to apply that diffuse irradiance map to the scene. This means that LGI adds the light from the diffuse irradiance map to the scene using lighting algorithms.

作用
LGI 模拟全局照明。全局照明是光线在现实世界中反射的方式。LGI 可以为场景添加逼真的漫射照明。
工作原理
局部全局照明 (LGI) 使用反射探针不断重新渲染局部场景区域。这意味着 LGI 会在相机周围的区域中创建光线图。
然后，LGI 使用照明算法将该图转换为漫射辐照度图。漫射辐照度图是显示来自不同方向的光线量的图。
最后，LGI 使用后处理将该漫射辐照度图应用于场景。这意味着 LGI 使用照明算法将漫射辐照度图中的光线添加到场景中。
