Time to reveal "The Shallows II", the next instalment of the triptych.

I have been asked about a background story for the triptych, but I 
prefer to leave that to the imagination of the beholder :-)

Total cumulated render time was about 39 hours on a i5 laptop.

Very nice.   I like the concrete aggregate texture, the decomposed frame/riser
of the rowboat - and little things like the drag marks in the ground and the way
the plants are aligned.

love the image, wonderful atmosphere (in both senses).  cheers.

Thank you indeed!

The rowing boat was inspired by an image from Nuntasi Lake in Romania:
https://www.swyrl.tv/article/wir-sind-der-meteorit-der-auf-die-erde-faellt-beeindruckende-tv-dokus-zu-klimawandel-und-duerre
It was an illustration from a documentary on Arte earlier this year.

The concrete aggregate is not only a texture, but this texture was also 
processed and used as basis for displacement mapping in Poseray.

Thanks jr. I have to think about III now more seriously, and doing some 
long overdue homework...

Indeed this material really stands out !

Do you think such a result could be achieved using HG POV displacement or
isosurface displacement macros? If yes an include like you did for Granite would
really be worth it, and if not, maybe a tutorial ?

Thank you!
Note that displacement mapping is done using .obj or mesh2 files as 
input in Poseray. I really have no idea if HG POV can do this. However, 
I guess that isosurfaces could do the job but probably would be much 
slower (in render time) than the way through Poseray which generates a 
"heavy" output .geom file but renders almost as fast as a non-displaced 
object.

I gave some sort of tutorial last year:

It can probably be done with the meshmaker.inc that comes with POV-Ray.

A crude crackle cylinder example:

---%<------%<------%<---

#version 3.8;

#include "meshmaker.inc"

global_settings {assumed_gamma 1.0}
camera {
   location  <0,1,-10>
   look_at   <0,0,0>
   angle 20
}
light_source { <500,500,-500> rgb <1,0.9,0.8> }
light_source { <-100,100,-500> rgb <0.3,0.3,0.5> }

#declare Crack= function {
  pigment {
    crackle
    colour_map{
      [0, rgb .01]
      [1, rgb .05]
    }
    scale 0.05
  }
}
#declare R= function(u,v) {
  Crack(u,v,0).gray
}

#declare F1= function(u,v){(.5+R(u,v))*cos(u)}
#declare F2= function(u,v){(.5+R(u,v))*sin(u)}
#declare F3= function(u,v){v}

object{
   Parametric(
      F1, F2, F3,
      <0, -1>,
      <2*pi, 1>,
      500, 500, ""
   )
   uv_mapping
   pigment{rgb 1}
   finish{specular 0.5}
   rotate <60,0,0>
}

Ah! That is an excellent suggestion indeed. Something I shall have to 
play with... sometime...

For those using POV-Ray 3.7, be aware that there is a bug in
meshmaker.inc v3.7: It will set your scene to #version 3.5, no matter
what you put at the top of your scene file.

This bug is fixed in v3.8 and in unofficial patches based on v3.7.1, and
the file should work if you copy it to your v3.7 include folder.

Thank you indeed for this reminder! Personally, I almost always version 
3.8, but sometimes 3.7 also. I now copied the corrected version of 
meshmaker.inc from 3.8 to 3.7.

Hi Thomas,

This is even better than the first image, not really anything to critique. I
especially love the texture/worn paint on the boat, great work.

Looking forwards to the next image.

Thank you indeed Sean!

The boat (and surroundings) were inspired by a photograph of the Nuntasi 
Lake in Romania, from a documentary of Arte 
(https://www.arte.tv/fr/videos/099776-000-A/secheresse-en-europe/) not 
available any more. But I enclose a copy here.
