configuring VRML .mailcap

I've followed Scott Nelson's WWWtest page with mixed success.
You can use the guidance in
http://www-dsed.llnl.gov/documents/WWWtest.html
to set up your .mailcap to have a mosaic-type browser spawn the proper viewer
for .iv and .oogl files. So far so good. When I then point mosaic at an
.iv file on an anonymous ftp server or an .iv file on a local host, only
text pops up.

Attached is an extended dialog on this subject. I've been reading RFC 1521
for Multipurpose Internet Mail Extensions (MIME), the html internet draft
and various www help pages without success. I expect that a "mime.types"
file is needed as Scott suggests, but I haven't found a reference to one.

These messages are being forwarded in the hopes that someone on the list
can devise a clean way to configure .mailcap (or embed Content-Type info in
.html links) to facilitate 3D browser launching. Thanks for any help.

regards, Don

Don,

Re: auv.iv when using ivview as follows on your file, I got the following error:

% ivview auv.iv Reading file(s)... Running ivquicken... Segmentation fault - core dumped Inventor read error: File does not have a valid header string Occurred at line 1 in <user-defined file pointer> Error reading file auv.iv

but if ivquicken was turned off then everything looked OK:

% ivview -q auv.iv

I didn't look to see why ivquicken was failing; I'll leave that little exercise to you...

...

Re: opening local iv files using Mosaic: 1. modify your mailcap file (usually /usr/local/lib/mosaic/mailcap but might be /etc/mailcap. In general, there are several mailcap files on your system -- especially if you have an SGI like I do. Best idea there is to have them all point to a single real file) as follows:

world/vrml; showvrml %s world/iv; showiv %s world/oogl; showoogl %s

where 'showiv' is "ivview", 'showoogl' is "geomview", and 'showvrml' is your favorite VRML viewer.

2. modify your server mime.types file. This is probably why you can see my IV files since my machine is the server. When YOUR machine is the server (i.e. looking at local HTML files) then you have to also modify YOUR mime.types file. This file is usually /usr/local/etc/httpd/conf/mime.types

world/vrml wrl vrml world/iv iv world/oogl oogl

Note also that like mailcap, there are probably several mime.types files on your system. It's best to have them all point to one real file.

If the above solves your problem, then please forward these directions along with any additional comments to www-vrml@wired.com in case others are having the same problem.

Thanks for your interest. Also, feel free to create pointers from any of your pages to our Viewer Test Page: http://www-dsed.llnl.gov/documents/WWWtest.html

If you have an httpd server running then the mime.types file is in /usr/local/etc/httpd/conf

If you have zmail (MediaMail) then the mime.types file is actually one or more of the following: /usr/lib/Zmail/attach.types /usr/lib/Zmail/bin/type-by-suffix /usr/lib/Zmail/bin/type-by-magic

There are also mailcap files (either the above) or in /etc and /usr/local/lib/mosaic

Hope this helps...
