TracePro is a general raytracing program for illumination analysis, optical analysis, radiometry analysis, and photometry analysis. It is the first optics software to be based on the industry-standard ACIS solid modeling kernel from Spatial, Inc. It is also the first software to combine true solid modeling, powerful optical analysis features, strong data exchange capabilities, and an enjoyable graphical interface.

TracePro is used in a variety of analysis applications including:

* Automotive
* Aerospace
* Display
* Lighting
* Medical
* Laser Component
* Machine Vision
* Consumer Electronics

TracePro is used to model:

* illumination systems
* luminaires and light fixtures
* automotive lighting: headlights, taillights, interior and

instrument lighting

* telescopes
* camera systems
* infrared imaging systems
* remote sensing systems
* spectrometers
* light pipes and multi-mode fibers
* integrating spheres
* projection systems

TracePro has a full set of features for solving your illumination design and optical analysis problems. TracePro Expert, our flagship edition includes many advanced features as well. The following is a brief summary of TracePro features.

* CAD graphical interface including interactive zoom, pan, and rotate, render, wireframe.
* Object-oriented Windows code for unlimited capability.
* Comprehensive geometry modeling - any CAD solid model can be
imported into TracePro and ray-traced.
* CAD data exchange - import any SAT file (included with all TracePro editions), or IGES or STEP file (option).
* Healing module lets you repair faulty geometry imported from other CAD programs (option).
* Lens design file import (option) from OSLO, CODE V ZEMAX ACCOS Vt, or Sigmat.
* Silhouette, wireframe, and rendered viewing modes with graphical editing capability.
* Complete solid modeling capability including Boolean operations (intersect, subtract, and unite).
* Solid Object editing features: Move, Rotate, Scale, Cut, Copy, Paste, Insert.
* Surface editing features: Sweep and Revolve.
* Comprehensive macro language (Scheme) allows complete automation of TracePro including optimization loops.
* Monte Carlo ray tracing with variance reduction techniques (ray splitting and importance sampling).
* Properties database including many standard properties, plus user-defined properties.
