Some of that looks like stuff I spilled on my lab bench when I was an organic
chemist, and then it crystallized as it evaporated...

That looks like a lot of imaginative fun, and all I can say is - WOW - that's a
really great image that will be fun to explore.  :)
Thanks as always for sharing your talent.

First, since "Avatar" an amateur doesn't seem to have any chance to generate
real 3D art anymore - at least this is my opinion.
All we do is just for fun. For me this insight is kind of relieving.

So I forget having to make nice images - if an idea works, fine - otherwise it
gets stored...

Second, I use win7 and swapping is nearly impossible nowadays.
My main render machine has 32 GB and I plan to upgrade to the maximum of 64 GB
(sic!). This is not only because of the motherboard, my processor (i7-5960X 3.0
GHz) doesn't support more than that IIRC.

I haven't seen a 40 GB scene yet, but perhaps I generate one - it should be easy
without meshes...

Happy rendering
Norbert

Yes, really inspiring... I just have the urge to plagiarize him.

   Somehow I like this part rendering better than the whole image:
subpixel detail is nice, but actually seeing all that nice detail is
better. :)

Your are a chemist - nice to meet a colleague!

Crystals are right keyword! I thought of replacing the prisms with Jaime Vives
crystals - hmm wait, why not doing it...

Hi Jaime,

I know what you mean :-)

But in order to maximise peak memory I placed more details...

In fact I made a 32.000x18.000 image and scaled it down via Photoshop. For me
this way is more effective than rendering with AA 0.00 +am2 +r4 or so. The parts
are from a 8000x4500 image version.

My hope is to get soon better monitors on the market together with faster
networks - 1920x1080 images have severe quality restraints! ;-)
I remember the old days with 800x600 images...

In the meantime I play with your crystals code to replace the prisms in my image
(I hope they don't rise the memory need).

Norbert

It is good. Now I want one with the camera offset so I can make a 
stereogram. ;-)

You make me want to revisit my "Machine at the centre of the Earth" 
animation.

No worries. It did mean that I had to take off my socks to do the

Very good. I love the fact that you could achieve such a result without
light_source. Now I wish to experiment this too in the future.

Thank you!

The method is very simple. It is similar to what I did in my last images (
http://news.povray.org/povray.binaries.images/thread/%3Cweb.56d73e91a21f2b01ee9ab14f0%40news.povray.org%3E/
).

The source for the top right one (Primitives1.pov) contains the method, but is
less memory-intensive than the current image.

Here is my final version.
Only two changes -

hexagonal "crystals" instead of prisms (thanks to JVP),
updated and blurry shuttle texture.

Full source is here -
http://news.povray.org/povray.binaries.scene-files/thread/%3Cweb.56f6c7cb60a8fcae1d8585d00%40news.povray.org%3E/
..

Scene used ca. 30 GB memory, so be careful...
Next week I'll update my render machine to 64 GB - are there any tips for a
scene using this amount of RAM?
