刚好看到一篇文章，我的理解：payload应该是一个自定义数据结构，用于存放进行求交或者着色计算时的一些附加的必要信息，单纯的函数调用或者光线信息并不足以支撑某个点的着色计算，所以需要传递一些附加的信息。参考链接：https://new.qq.com/omn/20190527/20190527A0A2D2.html?pc

谢谢你啦，分析资料很棒！

我顺便查了一payload
英文定义：
1: the load carried by a vehicle exclusive of what is necessary for its operation
especially : the load carried by an aircraft or spacecraft consisting of things (such as passengers or instruments) necessary to the purpose of the flight
2: the weight of a payload

中文翻译：
payload属于名词意思有：有效载荷（卫星或航天器携带的仪器设备等）；收费载重（船舶、飞机等的收费运载量，如乘客、货物而不包括燃料）；（炸弹或弹头的）的炸药量。
