  TracePro Overview lLv0lf  
sMK/l @7  
Like LightTools, TracePro is an solid-modeling based illumination modeling program with a Windows-based interface and CAD import/export capability O

TracePro modeling capabilities are similar to LightTools but with significant weaknesses that make it harder to use and less flexible, and is especially limited in 3D texture modeling compared to LightTools `Ii>wb

TracePro analysis features are similar to LightTools, but LightTools is much stronger as an interactive design AND analysis tool

LT (5.1) has flexible features to parametrically vary all 3D texture features (spacing, size, angles, depth, etc.) by equation or by direct “placement lists” imported from spreadsheet or other software Um|:AT}`^

看来楼主对这两个软件深有了解吗！佩服佩服...

Shiloh,你好！你的帖子非常好！谢谢！
