Guys -- Seth wants us to use .spaces. Can you change your respective code so the next time you generate output, you (a) ditch the .trans. in your output, and (b) use the .rooms extension? I am setting up a full campus run right now, and changing these file names is a pain! -- * * * Patrick James Nichols II Graduate Student, MIT Computer Graphics Group http://graphics.csail.mit.edu/~pnichols
