I am growing increasingly frustrated with the docs inclded with POVray
3.1. While I think they would be excellent in a classroom setting with
an instructor present, I find them tedious and difficult to learn from
in an individual "living room" setting. Presently, I am looking for an
example Object Media statement. I went to the trouble of printing the
manual so I could jump back and forth from section to section, as is
unfortunately frequently required, and I can't find one example of an
Object Media statement in my hard copy or on screen. Sure there's
pseudo-examples such as:
object{MyObject pigment{rgbt 1.0} interior {media{MyMedia}}}
but without a context, I find it difficult to get anything from that
at all. I have also tried using the statements from the insert menu, to
no avail (keeps giving me syntax errors, but I haven't been able to
figure out how to correct it/them), as well as visually searching the
files and statements included with POVray.
I apologize if I have offended the writers, or if I am simply being a
bonehead and not finding something that IS there, but can someone please
give me an example, or tell me as specifically as possible where I might
find it in the manual? I want to apply media to a Sky_Sphere, if
possible...
Also, while I'm here: Does anyone know of a POV user in Edmonton,
Alberta, Canada? If so, I'd like to communicate with them...

You cannot apply media to a sky_sphere. Sky spheres are not objects
like spheres, cylinders, and boxes. You can think of them as more
like a fancy light source.
Examples of media can be found in the following location / listed by name
if you followed the standard POV-Ray for windows installation.
Directory of C:\Program Files\POV-Ray for Windows v3.1\scenes\interior\media
GALAXY.POV
HOLLOW1.POV
HOLLOW2.POV
HOLLOW3.POV
MEDIA1.POV
MEDIA2.POV
MEDIA3.POV
MEDIA4.POV
MEDIA5.POV
Also check the povray.binaries.scene-files and povray.text.scene-files
groups for more examples posted by visitors to this news server. I have
posted at least four examples that I can recall off hand and many others
have done the same.
A couple of online media tutorials exist at -
http://members.xoom.com/POVRAY3/media1.html
http://members.xoom.com/POVRAY3/media2.html
Also see my home page for a media example that shows you how to use
color list patterns (i.e. brick, checker, and hexagon) using media -

There are also more media examples available at the POV-Ray objects
collection, a candle flame example I submitted, and a flame thrower
flame from H.E. Day - Both in the burning and fire section -
http://povobjects.virtualave.net/
And lastly for the ultimate resource of complex media statement check out
this site based on the IRTC award winning image "First Strike at Pearl" -
