fr2bp - convert fullrays to bpipe format rays
fr2bp converts fullray format rays to bpipe format rays. To preserve compatibility with the bp2fr converter and the drat module within OSAC, fr2bp ensures that if the surface number as read from the parameter file is 0, the surface normal data field and the graze angle data field are not added to the bpipe.
If the surface number from the parameter file is greater than 0, these two data fields are added to the bpipe output stream, and a surface number header field is created with a value of 1. Since only a single grazing angle field is written out, the value of surf_num is used to determine which of the two grazing angle fields in the fullray ray is written. A surf_num of 1 causes the first field to be output; values larger than 1 cause the second to be output.
