OPTIONS
   Debug Options
       -debug <integer>        Output intermediate result according debug level.
                               Default -debug 0

   Radiosity Options
       -adapt_area <float>     The threahold of adaptive splitting algorithm.
                               Default -area 5.000000
       -sample_area <float>    When the difference of form factor for each vertex is
                               greater than delta form factor, it should try to split.
                               Default by model-dependent
       -converge <float>       The radiosity B is the energy per unit area unit B is too small.
                               Default -converge 1200.000000
       -delta_ff <float>       The difference of delta form factor which is smaller than delta_ff
                               will consider as the same.
                               Default -delta_ff 0.000005
       -write_cycle <integer>  Write the status of radiosity for each write_cycle iterations.
                               Default -write_cycle 10
       -triangle <integer>     The maximum the number of triangles in the model. If you show image
                               on WebGL, set -triangle 30000 is the best resolution
                               Defulat -triangle 1000000
       -light <float>          Adjust the scale of bright light for testing.
                               Defulat -light 1.000000
   Output Options
       -zip                    Compress output file by zip.
                               Defulat false
       -o </<path>/file>       Assign the prefix filename the output file
                               Defulat ./test
       -interactive            Transfer the result into WebGL each write_cycle
                               Defulat false
