The story:
I decided to do something *without* isosurfaces and *without* radiosity and
therefore played with some superquadric ellipsoids.  But of course i could not
resist trying out how it looks with radiosity - and it really was much better,
so ...  :-)

concerning isosurfaces - rendering time was already 4h30min ...

The textures were made using displace warps, I do not like the gray/blue one
right now, so it will probably be changed.

Comments, etc. welcome

Christoph

Just in case you didn't know, which it seems you don't, isosurface
superellipsoids render faster than the real superellipsoid object in
POV-Ray... Nice image.

Neat, I like it. Don't like the blue and grey one though. I wonder how it
would look with a chrome texture.

I know, and just checked it for this scene, it's about 25% faster here (without
radiosity), but I originally meant using isosurfaces with some pigment function
instead of the normal statement and that would be much slower anyway.

Thank You.

Thanks, i thought of something metallic too, but i first have to build up
something behind the camera to have a nice reflection.

That's a good thought, maybe try throwing something unexpected into the
reflection.

Nice image, very different but attractive. I like the positioning and
apparent random nature of the SEs.

I would love to see the source for this.

The positioning/randomizing is really not that difficult:

#macro Var_SQ()
superellipsoid { 
  <rand(RX)*0.99 + 0.01, rand(RY)*0.99 + 0.01>   
  material { 
    M_warped 
    translate <rand(RX), rand(RY), rand(RZ)>*10 
  }                      
}
#end  

union {  
  #declare CnY=0;  
  #while (CnY<60)   
    #declare CnX=0;  
    #while (CnX<60)   
      object { Var_SQ() translate <CnX, -CnY-2, -1> }
      #declare CnX=CnX+2;
    #end 
    #declare CnY=CnY+2;
  #end                    
}

That's a funny idea, but i thought about sticking to superellipsoids.

Cool! Looks videogamesque. Texturing/lighting/layout are all good I think.

'cept for that blue 'n' gray one. Say, that pillar reminds me of the cactus guys
in Mario 64. And the 45 degree angles and sandy texture remind me of the pyramid
from the same level.

I like these textures.

Can I please see your code for them. I have looked in the help file for
MegaPOV, but I still do not understand exactly how to use this feature.

I was just thinking, 'Mario' would look good, in tippy-toe position, in
place of the objectionable object.

How do the warps work...
I'm not familiar with displace warp...?

Description is not very detailed in the Megapov docu, i already suggested a
change for that.  Maybe have a look at the displace warp tables on my website.

Source code for the texture is in p.t.s-f

Indeed a nice composition! I like ALL of it's ingredients! It reminds me
of Boulderdash, actually.  ;o)  If anyone konws what that was. A game on
Commodore64 and Amstrad CPC464, and ... there was an Amiga version as
well, etc..

Oh, the good old days could return in some 3D game today, hmmm...

Don't know those games you mentined, but thanks anyway.  

I'm working on some changes, hope to have a new version soon, but real live is
quite a full time job right now ...
