VRweb 1.5 for UNIX
==================
This is the UNIX/X11 version of the VRweb VRML browser. VRweb is
developed by the Institute for Information Processing and Computer
Supported New Media (IICM) of Graz University of Technology, Austria.
More information can be found at the VRweb home page:
http://www.iicm.edu/vrweb
You should have read the README of the VRweb distribution (ftp parent

The current release (incl. source code) is VRweb 1.5.

Installing the VRweb Help Pages
-------------------------------
Having downloaded the VRweb Help files, uncompress them the following
way:
gzip -cd help-1.5.tar.gz | tar xvf -
This will create a subdirectory help, which includes the VRweb
Installation Guide as a file called install.html and the VRweb Help
entry page as vrwebhlp.html.
The information below is also contained in the VRweb Help files, so
you may, if you wish, stop reading here, download the hyperlinked help
pages, and browse those instead.
AsciiText
---------
For AsciiText support (labels/strings in 3D space) please download
file fonts.tar.gz and unpack it in ~/.vrweb (which creates a subdir
fonts):
gzip -cd fonts.tar.gz | tar xvf -
See the online help about how to use a different place.
(In case you have downloaded fonts.tar.gz prior to July 16 1996,
please fetch the current version.)
How to use VRweb for UNIX/X11
-----------------------------
The UNIX binaries are compressed with gzip. Run gunzip on the
appropriate version of VRweb and you have an executable. Make sure
that execute permission is set for the file (if necessary using the
command chmod +x).
Be aware that some internet tools may strip off the .gz extension
without having uncompressed the file. Check the file size with the
table above, then rename and gunzip the file manually if necessary.
Download and unpack the Help files as described above.
The *source* code distribution is a gzipped tar archive. You can
uncompress and untar it in one step with the command
gzip -cd vrweb-src-1.3.tar.gz | tar xvf -
All further necessary steps are explained in file INSTALLATION
contained in the archive.
To use VRweb as a helper application with a Web browser, you will need
an entry for VRML files in your ~/.mailcap file:
a) Netscape:
x-world/x-vrml; vrweb -URL '%u' -remote %s
b) Mosaic:
x-world/x-vrml; vrweb -mosaic -remote %s
In both cases make sure to place the full name of the binary
instead of "vrweb" (e.g. vrweb-ogl on SGI, vrweb-mesa on other
platforms, if you renamed the binary to these shorter name).
VRweb will run gunzip on compressed files automatically if necessary
(this is often done by your Web browser).
Omit "-remote" to start a new instance for every new scene (like in
earlier versions).
With Harmony (the Hyperwave UNIX/X11 client) use the appropriate
version of harscened (for more information on Harmony see
http://www.iicm.edu/harmony).
Call any program with argument -h for a short description of
its arguments.
VRweb Mailing List and Feedback
-------------------------------
See the README file in the parent directory or the VRweb home page
http://www.iicm.edu/vrweb for instructions.
