Hi everyone,

It's been a while since I've posted an image to these newsgroups. I can 
never seem to finish my projects...

The rock formation is composed of two isosurfaces: one for the head and 
another for the body. Each portion has it's own png file to give the 
impression of character.

The scene was rendered in two passes. The second pass adds the bloom 
effect. Low radiosity and high isosurface settings were used.

The whole thing rendered in just under ten minutes, thanks to the low 
radiosity settings.

Questions and comments are welcome, as always~

Sam

You're not the only one.  Excellent work though.  Has an effect you don't see
too often in POV-Ray.  Kinda like this one.

Thanks. No on the Rushmore idea. I find the whole prospect a 
spirit-crushingly boring one. Unless I did something to the of the 
presidents...

My first impression upon seeing Tek's image was that it was photo. Then
I thought, wait, those rocks somehow resemble the granite pattern. Then
I remember seeing the entry some time ago :)

> Keep it up.

Sure will. Here's another version of the same image, this time with a
little chromatic aberration and film grain (rendered in POV, sans bloom).

An impressive combination of effects.  Now you just need too much unsharp mask ,
excessive channel-dependent noise-reduction -- oh, and some of that hideous
purple digital-camera bloom -- and you'll have yourself a real photo.

I love this!  The "formation" has a lot of character built into it, but it 
still leaves the viewer believing that it's just a natural rock formation. 
Nothing appears to be "man-made" or artificial.  Very nice.

You know you have been raytracing too long when you see a render and 
instantly know what patterns were used.

It would be more worrying if you could recognize the isosurface function 
by looking at a shape, though.

Impressive... the rock texture reminds me of the sandstone cliffs at 
Bamiyan, Afghanistan, the site of the former giant carved rock Buddha 
statues blown up by the Taliban in 2001 - or even of the Buddhas themselves!

Cannot express my thrill that is based on the experience of the Archetypes.
Older than time itself, they are the glue that holds everything together. If
they were to stop doing what they do everything would cease to exist as though
it never were.

There are more than 22 of the Major Arcana renditions.

We usually don’t see code for such magnificence – want to learn more, please.

Ha! Good stuff. I'll keep this in mind, should I ever render a bearded man!

I'm trying to keep this in-POV. There will come a day when I only have 
POV at my disposal. Gotta be prepared....

This might be true with POV, since it's implementation of granite is so 
distinct!

I tried hide the functions as well as I could, while keeping the render 
time down. This meant *no* turbulence could be used.

Here's another idea (even though the RSOCP idea hasn't taken off yet). 
Why don't we make a vast, virtual storehouse of unfinished projects? 
Each object can be placed on shelves, each scaled down to about one unit 
(without stretching). Each member of the community can render a portion 
of the scene, based on the number of volunteers and individual computer 
specs. Of course, we would need some way of handling memory consumption.

Thanks! I can see area for improvement, such as the left portion of the

Thanks Yadgar! I almost made the texture like that of real granite, but

Enough cannot be said of these giants of consciousness. They exist beyond the
edge of time and space. If one were worthy of such a journey they would meet
these huge ten story statues that you never see moving, but look away for
second and they have moved. Able to do it all, they hold the blueprints of
reality creation. Whatever you seek is at hand but first you must give the
requested gift once approved, an approval that is not your decision. No one
journeys here alone and all can be granted. You will be asked to give of
yourself and that is the greatest gift of all and such small price to have it
all.

Okay, I'll just have to make the code suitable for distribution and pack 
the files into a zip. It will be posted to p.b.scene-files.

Is that Jungian philosophy? Psychedelic shamanism? I'm always interested

This comes from my head and my journeys with a friend and a spark of love. I was
informed that Jung had the more correct "philosphy" of all the writers. I have
not had time to read Jung but I am getting that he is the "most correct" Some
of what I have learned would likely be found there.

I'll be looking for your source and thank you. I'll run with it and make
something great as an effort of repayment.

As opposed to Freudian psychology? I would have to agree. I find Freud's 
analysis of the human condition to be much too animalistic; it doesn't 
give enough credit to the higher cognitive states of homo sapiens :)

Perhaps the correlation is linked to an unusually disproportionate 
allocation of project time versus grooming time...

Wow, I don't know if I'll ever be able to match that. The German and

I don't think I ever really used any special tricks for that image. The 
hardest part was making the pigment patterns match up for the isosurface 
head and isosurface body. It was just a matter of translating things. It 
looks like I posted the source here:

Oops, I didn't realize what you were asking for. I just posted an 
updated copy of the code to povray.text.scene-files. It's actually quite 
a simple effect to create. It's not physically accurate, but should be 
enough to get you started :)

Nice.  Not half bad for a demo scene.  Let's see... film grain, bokeh, chromatic
aberration, lens flare, lightsys... I guess JPEG artifacts are easy enough to
add.  That still leaves purple fringing, blue channel noise, crud on the
sensor.  Collect that into a coherent system, and we'd have a pretty
comprehensive camera model!

That's a pretty amazing image.  Bad, but in a good way. ;-)

When I was a kid, I had a camera that took pictures like this (on a large-format
negative!) Rather horrible results--but it was one of my most cherished

The houses? It's rubbish :( It's actually a test scene for a 
neighborhood of houses setup I was working on the other day. I idea was 
to test cells and place the appropriate unit block according to the 
surrounding cells. It works, but adding complexity seems to multiply 
certain problems like roof shingles not meeting up right.

My webcam takes aberrated shots similar to this. I had originally 
designed the code so that I could add fake elements to scenes and tie 
them into real photos. I can still do that, but I doubt I would be able 
to fool any of you :)

stbenge, I tried your aberrate scene today and I can get the film grain to work
but not the chromatic abberation.  I've tried using both the default settings
and some random ones on my own.  Any advice as to what I might be missing would
be greatly appreciated.  I really want to try abberatting some pictures because
it will contribute a lot to my undetailed amateur images. =)  Thank you for the
work you put into this!  If it matters, I'm using POV 3.6.1 on a windows
machine.

Hello,

I tried it with 3.6 and it didn't work for me either. So I came up with 
this workaround. Replace the last object with this:

sphere{<0,0,10>,12
  pigment{
   #if(Noise>0)
    crackle solid
    scale .001
    color_map{
     [0 rgb 0 transmit 1-Noise]
     [1/6 rgb y transmit 1-Noise]
     [2/6 rgb 0 transmit 1-Noise]
     [3/6 rgb x transmit 1-Noise]
     [4/6 rgb 0 transmit 1-Noise]
     [5/6 rgb z transmit 1-Noise]
    }
    #else
    rgbt 1
   #end
  }
  interior{
   ior 1.0
   dispersion Aberration
   dispersion_samples Aberration_Samples
  }
}

I went ahead and uploaded a complete 3.6 version to p.t.scene-files.

Hi,

Thank you very much!  Your work around makes the chromatic abberation work as
shown in your previous pics.

I went through your code and just a few minutes ago saw that it was the effects
plane that was causing the problems.  As a temporary fix I just changed the
plane to box{2,-2 ....[the rest of the code in the plane block]...} .  It seems
to work too, but because you understand your macro more in depth than I do at
the moment I shall use the code posted by you.  Thanks again.
