Manual Pages

A manual page provides a description of a single radiance program documenting all options available with the program.  They are a good reference once you are familiar with Radiance, but don't offer much in the way of instruction for a new user.  You can access the manual pages on linux or Mac OSX systems from thee command line by typing 'man' followed by the radiance program name (ie 'man rpict').  If this does not work on your system then you probably need to set the $MANPATH variable.

You can download a PDF of all manual pages (in alphabetical order) or you can download a pdf for individual programs below.
