Trackers
Tracker (base class)– PolarisTracker– AuroraTracker
Support– SerialCommunication
SerialCommunicationForWindows SerialCommunicationForPosix
– NDICommandInterpreter
Object Representation SpatialObject
– Ellipsoid– Cylinder– Images– Mesh– Tube– TubeGroup– Group– Box ?– Cone ?
SpatialObjectRepresentation– Ellipsoid– Cylinder– Images– Mesh– Tube– Box ?– Cone ?– VascularNetwork SO ??– AirwaysNetwork SO ??– Surgical Tools ??
Viewers

Quality Control
Testing Platforms Windows
– Visual Studio 6.0– Visual Studio 7.1
Linux– gcc 3.2– gcc 3.3– gcc 3.4
Cygwin – Windows– gcc 3.4– gcc 3.3
Testing
Goal – 100 % Code Coverage– 100 % State Machine Transitions Testing
Current Code Coverage– IGSTK 93.6 % ( untested 321 / 4714 lines )– Sandbox 92.4 % ( untested 4 / 49 lines )
Dynamic Testing Platforms
Valgrind on Linux– gcc 3.3– gcc 3.4
Valgrind on Cygwin ( setup pending ) Purify (too expensive)
End
