|  |  | 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. Post a reply to this message

the suspense is _killing_ me.  :-)

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...

I. e. not just an normal map? Wow!
See you in Khyberspace!

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 ? Post a reply to this message

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...
