Please use 'run_fit.bat' in each subdirectory to run our fitting process for
reproducing all results in the paper.

The required input file (i.e., volumetric density + direction as well as
extracted fiber curves and ply centers) are provided.

The fitted parameters are stored in config_step2.txt, while fiber.txt contains
procedurally generated fibers in Mitsuba's hair format.

Note: Matlab needs to be available with its 'Initial working folder' set to
'Location based on Matlab startup rules' (under Preferences/General).
