LightToolsVsTracePro

TracePro Overview

Like LightTools, TracePro is an solid-modeling based illumination modeling program with a Windows-based interface and CAD import/export capability

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

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

TracePro Weaknesses

User Interface
Must move/rotate objects by dialog box only
Default naming convention (for spheres/elements, etc) is confusing and ambiguous

Modeling
Most elements cannot be edited
Must be deleted and recreated (including optical properties)
No unboolean capability
Boolean limited to two objects at a time
3D texture very limited vs. LT

TracePro Weaknesses

Ray Trace
No interactive (point & shoot) ray trace
No point sources; no volume sources
Clipped Lambertian sources are difficult (LED or fiber output)

Analysis
No illumination error estimate
Only 4 preset bins “available”
No 2D intensity distributions of full spheres
Limited ray sorting options
