      TracePro Overview KvtJ tql;  
    Z^%aXaf8  
    Like LightTools, TracePro is an solid-modeling based illumination modeling program with a Windows-based interface and CAD import/export capability g!!:o(k  
    BH2JH>'X  
    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 ETrL3W<  
    c>L#(D\\  
    TracePro analysis features are similar to LightTools, but LightTools is much stronger as an interactive design AND analysis tool

    3D texture modeling more flexible and much faster to ray trace in LT vs. TP z'd*z[L~  
    sQ8_j  
    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 -Rz%<`  
    Th[Gu8b3  
    When optimization is available in 2005, these parametric textures will make it much easier to design backlight systems
