希望大家都多給點(diǎn)意見(jiàn)

歡迎廣大背光朋友提出見(jiàn)解�。�！

我不是做背光的，對(duì)背光也不太了解 2|Of$oMc  
我想請(qǐng)教一下，做背光和做一般照明的區(qū)別。 ib$_x:OO"

謝謝！

還不錯(cuò)，挺均勻，不過(guò)真夠亮的

我也是做背光的，不知為什么，借用一下樓主的圖說(shuō)明一下問(wèn)題，得到的總是發(fā)光強(qiáng)度的分布，不像樓主是照度的分布，請(qǐng)大家指點(diǎn)。。。

新手 看不懂哦

學(xué)習(xí)中.........

你可以建立空間亮度接受器�。�

學(xué)習(xí)一下。。

How Many Rays Do I Need for Monte Carlo Optimization? BXzn-S  
While it is important to ensure that a sufficient number of rays are traced to Qru iQ/t

trace as many rays during optimization as you might to obtain a given level of Lm!/iseGv  
accuracy for analysis purposes. What matters during optimization is that the d ynq)lf

that the overall performance is affected. It is possible to define the merit function so y Tb
