最近閑的無聊，看zemax的macro 下面有個(gè)宏里自帶的macro，原樣附下，討論下標(biāo)記為 ****************************的作用，為什么要以漸暈為判斷標(biāo)準(zhǔn)，這個(gè)漸暈的真正作用是干什么的？附下RAYV（）->如果無漸暈則為0，否則為漸暈面的編號(hào)。(0 if ray was not vignetted,else vignetted surface number.valid only after a RAYTRACE or RAYTRACEEX call)。若大神賜教，小弟感激流涕············· 5W|u5AIw
