[Radiance-general] translate UNIX command into Windows command

[Ji Zhang]

 Dear Thomas and Radiance experts, one more question:

If I want to execute this rtrace command in windows via python, should I use
the tri-quotation symbol?

Is the following python script correct?

##################################################################################
import os

rtrace_command = ''rtrace -I -ab 1 -h -w -oov -u- scene.oct < sensor.pts > "
+\
                               """rcalc -e
"$1=$1;$2=$2;$3=$3;$4=179*(.265*$4+.670*$5+.065*$6)" > result.dat"""

os.system(rtrace_command)
##################################################################################


Thanks!

Ji
