Why that's just not true. There is documentation for Pov v3.1. The
layout is different but it exists as it did before. It even functions
the way it did in in v3.0x where you can place the cursor over a
keyword, press f1, and the documentation menu pops up giving you a
selection of relevant topics to choose from. I am not happy with the
way it's been structured in a non-scrolling format as it was but the
information is still being supplied. It appears you missed something
somewhere.

In support ov my previous post I just copied this from the v3.1
docs concerning the use of the New with Pov v3.1 function "Media"
Previous:Density Maps and Density Lists Main Index
Next:AtmosphericEffects
Multiple Density vs. Multiple Media
It is possible to have more than one media specified per object and it
is legal to have more than one density per media. The effects are quite
different. Consider this example:
object{MyObject
pigment{rgbf 1}
interior{
media{
density{Some_Density}
density{Another_Density}
}
}
}
As the media is sampled, calculations are performed for each density
pattern at each sample point. The resulting samples are multiplied
together. Suppose one density returned rgb<.8,.8,.4> and the other
returned rgb<.25,.25,0>. The resulting color is rgb<.2,.2,0>. Note
that in areas where one density returns zero, it will wipe out the
other density. The end result is that only density areas which overlap
will be visible. This is similar to a CSG intersection operation. Now
consider
object{MyObject
pigment{rgbf 1}
interior{
media{
density{Some_Density}
}
media{
density{Another_Density}
}
}
}
In this case each media is computed independently. The resulting colors
are added together. Suppose one density and media returned rgb<.8,.8,.4>
and the other returned rgb<.25,.25,0>. The resulting color is
rgb<1.05,1.05,.4>. The end result is that density areas which overlap
will be especially bright and all areas will be visible. This is similar
to a CSG union operation. See the sample scene
scenes/interior/media/media4.pov for an example which illustrates this.

it sounds like you're using Windows and he's using DOS. The DOS povhelp
program is indeed gone, but someone was going to revive it; check
.programming (I think) for info on this.

Oh ! If that's the case I apologize for my presumed statements.

If you do not have the documentation for the new features in
Pov v3.1 due to you using the dos version I will volunteer to
copy and paste the passages detailing the new features into
a text formated file for you. May take a couple of days but
I can understand your frustration if this is the case.

There is documentation in a text file, but the old povhelp program that
handled hypertext, paging, and other cool features is gone.

I thank you, but the problem is not getting the documentation itself,
but getting the online popup documentation that I had in pov3.0. I copied
the povhelp program and the pov3.0 documentation to the pov3.1 directory
so I can use that, but that doesn't help with the new features.
Maybe I'll just print the documentation, so I can use the paper version,
although it's not as handy as the popup help. But at least it's definitely
much more handy than a big text file.
I hope that the guy making the povhelp for 3.1 gets it done some day. I
will be thankful forever.

I don't know much about povhelp's features, but if easier browsing is wat you're
after, you might try downloading the HTML docs and use the Lynx browser to read
them. It doesn't support graphics, but at least the hypertext is there.

It's not just the easy browsing, but the popup feature, ie. when I edit
the scene for example with qedit and then place the cursor over a
keyword and press alt-esc then the povhelp pops up with the help about
that keyword; this works because the povhelp stays resident in memory as
a TSR and pressing alt-esc (or whatever you have configured) activates it.
You can also copypaste easyly code from the povhelp to the editor. This
makes povhelp, IMHO, one of the best dos-programs ever made.
I have tried lynx for dos, but it really doesn't help my problem.

A good way to learn is to examine the source of the sample files and the
tutorials, render them, then go in and edit just one thing and see what
happens. Read the docs, then experiment with one keyword or another to
see what it's supposed to do.
Oh yes, if you're shaky on geometry and algebraic math, you _might_ want
to get a couple of textbooks and run thru the areas you're unclear on.
With POV, math helps.
