  TracePro Overview z))rk vL%  
T|p%4hH  
Like LightTools, TracePro is an solid-modeling based illumination modeling program with a Windows-based interface and CAD import/export capability 9*P-k.Bl  
OaKr_m  
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 Pv|sPIIB7  
JkI|Ojmm/  
TracePro analysis features are similar to LightTools, but LightTools is much stronger as an interactive design AND analysis tool

Misc. Comparisons, LT vs. TP AbQnx%$u  
?B`c<H"  
Some large CAD models consume 20-30% more RAM and more CPU time in TP vs. LT H> n;[

TP CAD import repair feature much slower than LT -I z,vd  
hVCxwTg^X  
Inability to edit properties of Booleaned objects in TP (easy and unlimited in LT) .

Luminance meter simulation is simple approximation in TP, much more flexible and accurate in LT X|4Kdi.r@  
ty@D3l  
Most operations in LT can be done by mouse, by numeric input, or any combination (fewer TP features are mouse-enabled) NFG~PZ`6R

LT online help is extensive and useful, but very limited in TP A6xN6{R!

ORA Tech Support for LT is by a dedicated team or experience illumination and optical engineers

3D Texture Comparisons gRw? <U^

3D texture modeling more flexible and much faster to ray trace in LT vs. TP =`!#V/=  
}_Y\6fcd  
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 Z5*O\kJv

When optimization is available in 2005, these parametric textures will make it much easier to design backlight systems

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！
