int main	(	int	argc,

In this unit, we first launch a master thread and initialize the necessary data structures. This include the command line options (cfg), tetrahedral mesh (mesh) and the ray-tracer precomputed data (tracer).

parse command line options to initialize the configurations

The master thread then spawn multiple work-threads depending on your OpenMP settings. By default, the total thread number (master + work) is your total CPU core number. For example, if you have a dual-core CPU, the total thread number is 2; if you have two quad-core CPUs, the total thread number is 8. If you want to set the total thread number manually, you need to set the OMP_NUM_THREADS environment variable. For example, OMP_NUM_THREADS=3 sets the total thread number to 3.
