Photon Engineering 非常高兴公开最新版本的 FRED , 我们的高阶光学仿真软件 FRED 7.50.0 版本更新许多功能。包含了 多核心执行效能提升、增加 volume scatter 及 coatings 的 Script 指令、简化 CAD 汇入的对象数量、新增光源档类型及新光源文件汇入界面等等。还有许多配合新功能的 Script 指令被加入到这次的版本更新之中；使用者可以在新版本 Release Notes 中找到新功能说明。

新版本 FRED 在汇入 CAD 档案 (IGES 或 STEP) 后，预设为一个新简化的形式树状列，自动隐藏被用来使用于孔径与削切的线段与表面，使用者可以得到更精简几何结构树状列。

FRED 在建立光源处，新增一个可以汇入二进制档案 ASCII 光源档案，并且可以自由设定汇入的光线数量。

FRED 本次版本更新亦将表面特性设定加入了 Script 控制的接口 . ，使用者可以控制的参数包含有、材质、反射率、工作波长等等，在新的 Scripted Coatings 设定接口中，可利用方程式函数的方式进行编写。

现在使用 FRED 的 开启旧档的对话框 ( 从 File=>Open ，或快捷键 < Ctrl+O > ) ，它的预设档案读取格式，为 FRED 窗口接口的 .frd 及 Script 界面的 .frs 档案类型；在此之前预设档案读取格式只有读取 .frd 的设定。

新版本 FRED 对于多核心系统的运算效能有着显着的提升，包含了追迹光线历史轨迹信息及光线路径记录时不再局限于单核心运算；另外照度运算、能量密度及 Scalar Field 等分析功能，皆可使用高核心数进行运算 ( Standard 版本 FRED 可支持双核心运算及 最高 8 核心运算的 FRED Turbo 版本 ) 。
