Polar ISO-Candela Plot表示的是什么?
-&UP[Mq 看了help里面的说明,如下: N#!**Q 0 %+F%C=GqI A candela plot is a plot of luminous intensity, or flux per solid angle. In photometric units, a luminous intensity plot is in units of candelas, or lumens per steradian. In radiometric units, the corresponding quantity is called intensity, and has units of watt/steradian. Candela plots are commonly used in the design of illumination systems. +jifbf- ZPO+ #, 但还是不懂,它跟Irradiance/Illuminence maps有什么区别呢? 4eh~/o&h 菜鸟问题,请赐教!
