Hi(gh)!

For quite a long time I did hardly anything POV-Ray-related than just 
manually editing the Kabul 1:100,000 heightfield or, more recently, 
collecting high-resolution OpenTopMap tiles for a more advanced version 
of that heightfield...

...and now, I want to re-create a level from the Amiga game 
"Rock'n'Roll" in POV-Ray (of course for animating it from the ball's 
perspective later on...) - and fail already at the very first step, 
which is creating a layered texture for a sky_sphere (or, simpler as not 
involving UV_mapping, for six planes forming a cubic space).

The lowermost layer consist of equally spaced squares - so I thought 
using the boxed pigment would be appropriate. But... whatever I try, I 
always only get uniform black!

Is it an idiosyncrasy of 3.7? Or do I simple lose the general ability to 
do anything sensible with POV-Ray?

Here is the code:

#declare P_Cubic_Division_Blue_Layer_1=
pigment
{
   boxed
   color_map
   {
     [0    rgb 0]
     [1    rgb 1]
   }
   translate <0, -1, 0>
}

// ACTUAL SCENE

plane
{
   y, -1
   texture
   {
     pigment
     {
       P_Cubic_Division_Blue_Layer_1
       scale 0.1
     }
     finish
     {
       ambient 1
       diffuse 0
     }
   }
}

camera
{
   location 0
   look_at <0, -1, 0>
   angle 40
}

Remember that that boxed pattern is not a repeating one. It is 1.0 at 
the origin and 0.0 at the sides of the box. You've moved the boxed 
pattern down to the depth of the plane with a translate, but then you 
have a scale 0.1 so the value at the plane is outside the box or 0.0 
always.

Your camera is also quite close to the plane so even moving to a scale 
of 1.0 for the boxed based pigment it might be hard to see the gray 
gradient. Perhaps use a camera angle of 80 instead of 40 or move the 
camera up the y axis.

Lastly, you might find the pavement or tiling patterns of use for what 
you are trying.

I thing boxed is not the pattern you want.
To get an image with it move the plane away from the origin.
Weird pattern.

Hi Yadgar -

I believe that boxed is a non-repeating pattern, and so is wholly unsuited for
what you want, as well as how you're implementing it.
Read the description - it is ONE box.
You would have to translate it -0.5, rather than -0.1 to even see it.
You have no light source.
You have an odd camera position / look at / with no sky to contrast with.

So in essence you're looking at the unlit black plane that you've defined in
your scene.

Here's my quick dabbling that you can edit and see what I mean:

=======================================================

#version 3.7;
global_settings {
 assumed_gamma 1.0
 ambient_light color rgb <1, 1, 1>
}
include "colors.inc"

// Create an infinite sphere around scene and allow any pigment on it
sky_sphere{ pigment { gradient <0,1,0>
                      color_map { [0.00 rgb <0.6,0.7,1.0>]
                                  [0.35 rgb <0.0,0.1,0.8>]
                                  [0.65 rgb <0.0,0.1,0.8>]
                                  [1.00 rgb <0.6,0.7,1.0>]
                                }
                      scale 2
                    } // end of pigment
          } //end of skysphere -------------------------------------


#declare P_Cubic_Division_Blue_Layer_1 =
pigment
{
   boxed
   color_map
   {
     [0    rgb 0.5]
     [0.5    rgb 0.5]
     [0.5    rgb 1]
     [1    rgb 1]
   }
   translate <0, -0.5, 0>
}

// ACTUAL SCENE

plane
{
   <0, 1, 0>, -1
   texture
   {
     pigment
     { //checker Red, Blue
      P_Cubic_Division_Blue_Layer_1
       scale 100
     }
     finish
     {
       ambient 1
       diffuse 0
     }
   }

}

No, it's not unsuited at all - at least when I use warps! So I did, and 
it worked quite well (see attachment)... but now another problem arises 
(of course, that's computing!): the inner boxes (uppermost texture 
layer, see code) should have a concentric color gradient from greyish 
blue to white - but instead, the gradient is centered in the lower left 
corner, as if the box pattern uses only a quarter of the entire box! How 
can I fix this?

The code:

   diffuse 0
}

       [0.00001 rgb <0, 0, 0.192>]
       [1 rgb <0, 0, 0.192>]
     }
   }
   finish { F_Background }
}

Does POV-Ray support infinite sky_box sort of like sky_sphere? This may 
be a good addition in a future version.

boxed evaluate to 1 at <0,0,0>, that value drop to zero at 1 unit 
distance in all 3 directions forming a box going from <-1,-1,-1> to <1,1,1>.
Outside that box, it always return zero.

The other similar patterns are planar, cylindrical and spherical.
planar evaluate as 1 on the X-Z plane and drop to zero at +-Y.
cylindrical is a cylinder around the Y axis with a radius of 1.
spherical drop to zero at radius 1.

All those remain at zero outside those domains.

Hi(gh)!

After deciding to discard the smooth color gradients in favour of sharp 
stripes (which would be more true to the Amiga original), I now fixed my 
problem with the background texture (see attachment).

I now will apply this layered texture to six planes defining the cubic 
space in which the game level is located; they will be animated 
according to the player's (a simple ball) movements, just like in the 
original game!

Congrats on working it out   :)

Nice use of warp and repeat.
I always forget about the warp feature - so many things to use in POV-Ray   :O

...but then I accidentally deleted all *png files in the POVnroll 
project directory - and among them also the level 1 mosaic, cumbersomely 
screen-copied from the Amiga emulator! So I will not be able to resume 
my work, unless I do it all over again! Perhaps not all - a partial 
version of it is on my friend's harddisk, but I have to phone him to 
e-mail it to me, he does not regularly check his e-mail...

Computing sucks!!!

Are you telling me you don't have backups??? My file server runs ZFS in RAID 1
with snapshots. You should consider doing something similar.

Take backups!  Take backups!  Take frequent backups!

And be sure to back them up to a different device--another hard disk, the cloud,
something.  One POVer did his backups to the same disk, and lost every single
one of his scene files.  All of them.  GONE.

I have had my hard disk crash *twice*.  I'm sold on external backups.

I once accidentally erased my user directory after getting my working
directories mixed up.  I'm sold on external backups.

Can't afford an external hard disk?  Live on sandwiches for a month.  It's worth
it.

Good advice! The cost isn't like it was a decade or more ago.

Was easier before I went exclusively to notebook computers, now I must make the
conscious effort to connect the external drive.

I must have several complete sets of backups, excluding the most recent files.
At least 2 always current, using a couple multi-terabyte-sized external drives.

Maybe a dozen copies of older files on tape (tape drive gone though), CD-R,
DVD-R and HDD. Not very organized, so that can be a problem if I had to resort
to locating something again. I certainly can't claim to be efficient, more like
sloppy in how I do things.

Absolutely right! Sandwiches and water (not that delicious Cologne beer!)

And use a synchronising program to copy it all neatly. I have been using 
GoodSync for many years.

A backup to the same drive is NOT a backup at all but a copy, it's just 
a waste of space.

If it's on a single device, it's not backed up.

If it's in a single location, it's not backed up.

Meanwhile, I was able to restore that crucial file, using a free NTFS 
file recovery software... but then I noted that I already had send this 
file as a e-mail attachment to friend, so all that fuss was unnecessary!

So I could continue working on Level 1 of POV'n'Roll... here is what 
I've come up with so far...

See you in Khyberspace!

Oh dear! Is it that bad? Been a long time since I was in Cologne last. ;-)

I did like German beers though (when I used to drink beer) more than 
Dutch ones (with some exceptions)...

Some would say that "Cologne beer" is a contradiction in itself.

I'd disagree, and argue that the contradiction is instead in "delicious
beer".

Before my discovery of Belgian beers, "good beer" was uther non-sense 
for me.
I've changed my mind. Main stream Americans beers are awfull, main 
Canadian ones are somewhat better and micro brewries ones are OK to 
really good.
