[Radiance-general] X 11 trouble with OS X

[Dave Bosworth]

No, I had to install X11 to run Matlab.  I have installed: X11 1.1.3 - XFree86 4.4.0

Does rview usually open up x11 on its own, or do I have to boot it up separately?

finally, is rvu the same as rview?

thanks for getting back to me so quickly!

cheers

Dave
