[讨论]macros [复制链接]

       最近闲的无聊，看zemax的macro 下面有个宏里自带的macro，原样附下，讨论下标记为 ****************************的作用，为什么要以渐晕为判断标准，这个渐晕的真正作用是干什么的？附下RAYV（）->如果无渐晕则为0，否则为渐晕面的编号。(0 if ray was not vignetted,else vignetted surface number.valid only after a RAYTRACE or RAYTRACEEX call)。若大神赐教，小弟感激流涕············· ]de\i=

Kimclps兄果然学识过人，受教了·····

不敢當，互相切磋。
