材质底色

有没有哪位知道除了第一个参数，其它三个参数分别是什么参数？

材质底色 相当于修改模型本身的颜色
散射强度 则修改的是散射光线的照射强度
镜面强度 同上，
如果不太理解 散射强度 和 镜面强度，可能得看下图形学的书籍。。

No source file, test, or entry point is mentioned; begin by identifying the material-control implementation represented in the attached image and reading the related Cesium or EarthSDK API documentation. Done means documenting what the three parameters after the first one represent and how they affect the material, with wording that a user can understand.
