I've been playing with the ambient settings.
<BR>I'm looking for a function that can be used to keep an object's color
roughly the same when you add ambient.
<BR> What I did was place 2 boxes side by side one with ambient set
the other not and adjusted the color of the ambient box until it match
the color in the plain box.They where lit by a spotlight pointed at their
midpoint.
<BR> What I found was that with plain box set to rgb<0,0,1> the
ambient values and color where:
<BR>               
pigment           ambient
<BR>            
rgb< 0,0,1.17 >      0
<BR>            
rgb< 0,0,.633 >      .5
<BR>            
rgb< 0,0,.433 >      1
<BR>This is just a sample I tested every tenth point from 0 to 1.
<BR>From the data I have there is no linear function that works.
<BR>From the help file it says that ambient adds a small amount of white
light but that is as far as it goes.
<BR>If someone knows of a function that can do what I want then THANKS!
<BR>If not then I'll just have to do the math and come up with one that
I'll post here.

I'm not sure I understand what you want to achieve.
When you exclude specular highlights, reflections, transparency etc. the colour
of the surface can be calculated with the following formula:

(pigment * diffuse * light_colour + ambient)

The ambient value (rgb <0.1,0.1,0.1> by default) is simply added to whatever the
apparent colour of the object is at a given point (i.e. it just brightens the
object by a constant amount).
The value 'diffuse' you specify in the finish statement is the maximum value.
The actual value used for a particular point falls off from the maximum (where
surface points straight towards the light_source) to zero (where surface points
away from the light_source).

So the apparent colour of a surface varies greatly depending on how much light
it receives. When it receives less light, a higher ambient value is needed to
balance the lower diffuse lighting. Diffuse varies over the surface. Ambient
does not. There is no universal formula.

Sander,

For the most part it is a matter of courtesy for those who do not have
html enabled browsers. It has been agreed by many of our visitors that
plain text messages would be the best format for all people involved.

Put simply, a binary is any file that is not a plain text file. For
our newsgroup purposes, the following are examples of binary files:

  newsreaders that cannot automatically read HTML posts without

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.

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

I have no problem with a HTML post, as long as it's not loaded with background
images etc. The latter does annoy me though, since my bandwidth is limited and I
am strongly against useless bloat.
Flaming new users about HTML posting is indeed a rash thing to do. But the rule
of using plain text is not unreasonable IMO. After all, HTML has little benefit
in a discussion group - and as such, HTML ability shold not be the highest
priority in newsreader development.
I hope there won't be another flamewar on this subject...

HTML in many cases doubles the size of a message, it doesn't add anything
to the post, just costs me more to dl the groups.

I've seen a Vcard or two recently, but not many I'm glad to say. 

HTML is overkill for a text message, like using Power Point to write
a memo.   

My 2p worth, I'll shut up now.

Well, I just wanted to point out that there is another factor here at play. Ken and
Gilles had some very good points, but I do have a HTML capable news reader and I do
use that for reading, so I have no problems on that end. Where I do have problems is
with the HTML itself.

Often the color scheme looks poor for me (black on a full white background looks nice
on paper, but from a CRT it can increase eye-strain and fatigue). And then there's the
problems with the font specifications themselves. Often the fonts will be specified in
absolute sizes instead of in relative sizes (e.g. "SIZE=3"). This often makes things
almost unreadable for me, since I'm running a hi-res display. I mean, really, why are
you (the abstract HTML poster) forcing me to read 10-pixel fonts??? Why do you know
better than me what is comfortable to read with my setup on my computer? Additionally,
I am one of the average people who are more comfortable reading information that's not
splayed completely across the screen, but is instead kept in nicer columns. Plain text
posting is usually wrapped to 80 columns or less, and is more legible. HTML postings
usually don't as well. Take a peek at your average newspaper or magazine to get and
idea of what I mean about columns.

And then there's the bloat factor. I luckily live in the USA, and have DSL so I
personally don't have to worry much about this, but much of the world actually pays
per-minute for connections. Yes, there are binary posts here, but duplicating text in
HTML posts bloats those by not just x 2, but more. Just take a peek at this before and
after:

before:
        // sphere { <0.6725250, 0, 0>, 1.0, strength 1.0 }
after:
<br>        // sphere { <0.6725125,
0, 0>, 1.0, strength 1.0 }

before:
           diffuse 0.8
after:
<br>           diffuse
0.8

So that second copy in HTML is not only a duplicate, but much larger (for text, that
is). Plus the fact that the HTML version went and threw in extra line breaks where
it's just getting in the way. Bleah.



Anyway, I'm just trying to point out some other possible reasons to stick with
plain-text over HTML. I don't think the "my software doesn't handle it" is a very good
reason. I do think that how it might make things hard on others is more of a good
reason. However, I think it's mainly a point of being aware of different factors and
making an informed choice. Especially if your posting agent does nice HTML that works
well for most readers, then that's not as big of an issue.



And then there are the newsreaders that post in plain text and mark their posts as
such, but don't bother inserting the proper line breaks (guess which one is the worst
offender), which is directly against the actual Internet standards for mail and news
postings. Those realllllly bug me. Especially since I don't have my reader set to
'correct' for that broken behavior (since doing so can cause other problems).

How about this one! 
 I've had trouble lately when I'd load entres from a povray group. I get
a little box that ask if how many file I want to load and if I want to
mark the others as read.
When I load a few or all of them the next time I load the group it winds
up saying that there are fewer files to read. So somewhere trying to fix
it I must have change my output to <HTML>.

  There's no need to use HTML in order to talk about computer graphics. You

  The binaries groups are different. You are allowed to send binary attachments

Netscape seems to d/l the images twice here too, extremely annoying, I thought
it was something to do with the way I upgraded it.

I now read the binaries groups with a text based browser, I can have the 
attachments open in a seperate window at the press of a button (or two).

Off topic, - have you discovered ee *.jpg yet, it opens all the jpgs of the 
current dir as thumbnails, and the first image in a window the size of the 
image, you can navigate (the directory)  on the image toolbar or by clicking
on the thumbnails, very useful for camparing images like those door knobs 
the other day.

I have used Netscape exclusively since I started reading these groups
2-3 years ago. I have never had to download a message twice to see it.
I have heard others mention this before but I suspect it is operator
error rather than a problem with Netscape.

probably not.

It happens to me here, all the time.  On Linux and Win98 both. 4.6 and 4.7. But
since I switched to DSL it's been less painful (i.e. it double-downloads, but is
not too slow to tollerate).

This is only on Linux.  My only real dissapointment of moving to 100% Linux
is that what used to be a fantastic package for win95 totally sucks in its 
Linux incarnation, the mail clients all suck aswell, but it's stable and fairly
fast, and it's interesting.  Oh yess I can run 4 instances of Pov, all long 
(2-5 day) renders at the same time, and read my mail, my news, compile 
software, go surfing with out noticing that I've got so much going on in the 
background.

  It's not that I have to download the message twice to see it; it's that
netscape downloads it twice all by itself although I don't understand why.
The first time it downloads it, it looks just fine, everything is ok. Then
it starts to to download it again, for no apparent reason (funny enough,
this doesn't happen always, but most of the time).
  My expression "it must download the image twice" just expressed my
frustration.

Interesting you mention that, just yesterday I ran into that trap when
generating a simply html page with the Netscape Communicator Composer.
It is a really annoying bug...
