[Radiance-general] trouble in installing radiance on ubuntu 8.03-a new user

[Bernd Zeimetz]

Hi.

running

dpkg -L radiance

will list the files.
You should also install the following packages:
radiance-doc
radiance-materials
- especially if you want to have a look at the examples. They're split
into packages on their own as they're architecture independent. Listing
the files works in the same way, just use the different package name.

The manpages have been patched, so they'll show genrbox.

The commands are available under the old name if you add
/usr/lib/radiance/ to your PATH. Adding something like
export PATH=/usr/lib/radiance:$PATH
to your .bashrc or /etc/profile or to the rc file of your favourite
shell will help. Then you'll also be able to use rview.

The example scenes don't need it, you need to install the
radiance-materials
package, though. If RAYPATH is not in the environment,
/usr/share/radiance will be used automatically.


There's a README which explains these details in
/usr/share/doc/radiance, in case you'd like to have additional details
added, please send me a patch or an updated file.


Hope that helps,


Bernd
