The TraceVortex visualizer is TraceVortex.exe in your installation
directory. It also includes TraceVortex.py, the Python source of the
program. Running the source directly requires requires WxPython, and
PyWin32 if you're on Windows.
The TraceVortex Visualizer reads .vstrace log files produced by Vortex
programs that enable tracevortex logging. It provides an interactive
representation of the program's execution, allowing you to see which parts of
the program took various amounts of time.
.vstrace log files contain line number references to the Vortex source
that ran. You'll need the Vortex source code that made the log available
when analyzing the .vstrace log.
