<HTML>
What I am trying to do is use 'ambient' to make an object's shadow stand
out.
<BR> If you set up the pigment of an object then find that a shadow
isn't right.
<BR>So you add 'ambient' to the finish to get the shadow right then the
pigment is to bright.
<BR>To get the new pigment(in shadow) the way ya want and the new pigment
(out of shadow) to match the old pigment (out of shadow) you need a formula.
I used the program above to try and find one.
<BR>When I got the ruff data in I found that the it was not simple to add
or subtract a number from the pigment.
<BR>I have come up with a formula:
<BR> #declare AV=AmbientValue;
<BR> #declare PA= -.422*pow(AV,3)+1.305*pow(AV,2)-1.62*AV+1.17
<BR>Now if I have a pigment I want to adjust the shadow all I have to do
is mutiply by PA and change the Ambient value.
<BR>I haven't try this 'filter' and 'transmit' and it problily won't with
'defuse'
<BR>Thanks for the formula it'll help in exploring these showdows.
<BR> </HTML>

What, you like having advanced article-management (and moron-management)
features? What kind of throwback are you?

Yep, that's about how it looks for me too. And it's not even valid HTML;
consider "rgb<0,0,1>". That last ">" should be ">".

My 2 cents :
To be frank, this limitation would be logical it if this were, say, a newsgroup
about rural farming in tropical countries where the users are likely to have
limited computer resources. But this NG is dedicated to computer graphics, and
used by people who have up-to-date configurations, if only to run CG software and
Internet connections able to download binaries. I've also noticed that the people
who seem to have trouble with HTML postings are also rather advanced computer
users, which doesn't make sense... When I have trouble reading a file because of
a new popular format, I search for the latest version or patch that supports it
and always find it. This what I did when I started receiving HTML-coded e-mails.
Is that really impossible for HTML post reading, even without using Netscape ? Or
is there something sentimental about using non-HTML supporting newsreaders ?
What annoys me is not actually the ban on HTML posting itself (which I don't find
very useful, though it could come handy sometimes), but the fact that new users
here get flamed for this the first time they post, when sometimes they don't even
know they're doing HTML posts because it's the default mode in popular
newsreaders or email programs. This is not a "courteous" way to welcome people,
IMHO.
For the record, the policy n the French pov group is to allow HTML posting and we
haven't had any complaints so far, except the occasional joke on the occasional
ugly background or HTML mess, which is still better than flaming newbies for
something they're not guilty of, and starting threads about it.

You know Gilles I agree with you almost completely. A very vocal minority
have have asserted that html posts are an -inconvenience- for them and that
in order to read posts that are in html format they have to use a separate
program that will read them. This implies they have the resources at their
disposal to handle html posts but stick with software that does not support
it out of preference. In this case the minority are controlling the majority.
Personally I use Netscape that can and does handle html posts without problem
- even in the French NG's with their tacky backgrounds :)
One last point though is that html posts do take up more space on the
server and if more people posted in html is would chew up server resources
at an alarming rate. Unfortunately the server resources are not unlimited
nor are the funds that provide them. I personally will shed a tear or two
the day that this servers resources become so strained that automatic
expirations on messages has to be applied to provide new resource for future
posts. There are some great messages here and some of them I refer back to
often for my own edification as well as the edification of others.
These facts aside this news server admin. has made it policy on this server
to ban html posts. As one of the people on this server who often greets new
visitors for the first time I try to help enforce this policy. I do however
try to do so as politely as possible when pointing this out to new visitors
and never attempt to "flame" them in the process. I also take the time to
explain why this policy is such as it is in the hopes that they understand
that it is not a flame as much as it is a necessity for all people involved.
I would like to encourage everyone on this server that if they do take it
upon themselves to "correct" someone for posting in html, rather than in plain
text, that they do so politely and take the time to explain it to the person
why plain text is necessary. Otherwise it does come off as a flame and some
people may take it personally and never come back. That might be as much our
loss as it is theirs for you will never know what their future contributions
to the POV-Ray community might have been nor what they might have received
in return from us.

I started asking why you don't like using an html- browser, but I suppose
it's none of my bussiness. The snapshot.gif was very instructive, though!
Was that done in Linux?
Now I realize that my answers to html-posts have been html also,
unwittingly. Especially annoying when you repeat a picture also... Is there
a really quick way to see that a post is html in MS outlook express 5?

The main problem I have with using Netscape to read news is that it has horrible
keyboard support, no support for scoring posts, and a cramped, ugly interface
that makes me scroll far too much (800x600 screen, not by choice) to read a
simple 30-line post. On top of that, having to switch back and forth from the
message pane to the message list is annoying in the extreme. My explanation
for why I use slrn is simple: I touch-type and I have tendonitis. Interfaces
that force me to take my hand off the keyboard and move the mouse to a tiny
scrollbar button to do something I do often are not interfaces that I use for
long. In addition to that, Netscape has far too many bugs and idiosyncrasies
that I don't want to have to deal with. Outhouse Express is worse.
It looks like you're falling into a common trap: you think that just because my
newsreader doesn't support HTML that it must not be state-of-the-art. In fact,
it supports far more _useful_ features, such as scoring and scripting, than
Netscape ever will, and takes up less than a megabyte of hard drive space in
the process. On top of that, it's configurable, so I can add all the NNTP
headers the Netscape designers thought were unnecessary when I need them (such
as Expires: ) And if HTML support is the hallmark of an advanced newsreader,
why is it that only two of the dozens of available newsreaders have it, and
none of the others have plans to add it anytime soon?
Finally, when the next killer ActiveX/Javascript trojan comes along, I'll be
immune. Will you?

Yes, I have Netscape. I use it to look at the pretty pictures in p.b.i,
because it's more convenient in that case. But I use slrn even to read the
non-binary posts in p.b.i, just because it doesn't force me to use the mouse
to do everything useful, and because it does things Netscape just can't do
and has configurations Netscape just doesn't have. Besides that, it's open
source, and I'm kinda partial to open source. I've even modified my copy of
slrn, as you should all recall, to strip objectionable vcards. Let's see you
(the generic you, not Ken or Gilles) do that with Netscape. (Yes, I know
about Mozilla. Come find me when it's ready for normal people to run.)
Someday, I'll teach slrn to strip the common tags from postings made with
Netscape, particularly the nbsp travesty, and then I'll stop complaining
because all that HTML will be human-readable again.
However, I do agree with both of you that if we're going to ask new users not
to post in HTML, we should do it quietly and with respect, and preferably with
directions on how to turn off HTML posting in their newsreader of choice.

Your views on this subject are well documented on this server. Funny
though that when someone suggests that since they are left handed they
are discriminated against by the right handed populace everyone says
learn to live with it Mr. Minority. When the minority non-html compliant
news reader people protest they get all of the support they want. What
a cruel twist of fate. < Insert big smiley >
P.S. I don't recall a single vcard posted here since the big debate.
