[Radiance-general] gensky

[Thomas Bleicher]

Jia.

The current official release is 4.0 from radsite.lbl.gov. This package
contains all files for the core tools. It does not contain source
files for libtiff which is only required if you want to compile the
tool ra_tiff which allows conversion from and to TIF images. However,
there is a small bug in the makeall script: if it can't compile
ra_tiff it will not install any of the other converters. It will
report errors instead.

To avoid these errors you need to download an additional package,
rad3R9supp.tar.gz (or any other archive). This file contains the
libtiff sources and a lot of other material (example scenes, images,
mesh objects). It's a pretty big file and because it's not essential
for the core Radiance tools it was spit out in a separate package.
Don't worry about the version number. The "supp" file should work with
the new 4.0 Radiance from radsite.lbl.gov. All other files on
radiance-online.org need to be updated. The official 4.0 release of
Radiance is only a couple of days old so there was no time yet to
update that site, too.

The best way to compile is:

1) Download and unpack rad4R0all.tar.gz. This will create a "ray" directory
2) Download and unpack rad3R9supp.tar.gz. Unpack this in the same
directory. This will extract its files in the same "ray" directory
that was created before.
3) cd into "ray"
4) compile with "sudo ./makeall install | tee makeall.output"

This will create a file called "makeall.output" with all the stuff
that's scrolling by on your terminal during the process. You can check
it for errors later. If you see the message about errors again send
this file and we can see what was going wrong.
