Fish underwater blob topo with pipes and flanges.
Needs a bit of cleanup to remove some parsing errors.
Mostly a material and scene idea study.

Yep...had to resample the bitmaps. Posted a new file. Should be on its way. :)

Also, a bit of warning.
The 'populate' macros are slow to process with the amount of objects I'm using.
Not well optimized - could us some type of culling to remove unseen plants.
The random scale factor needs tweaked. I messed it up but like the size
variations, so I left it for this rendering. :)

I will think about it, some optimization is always necessary.
Write now I can suggest bounded_by:
https://wiki.povray.org/content/Reference:Bounded_By_Object_Modifier
if you still not using it. It's very effective for the scenes with large
amount small objects with complex shapes.

It's possible that certain versions of POV-ray mistakenly remove any manual
bounding shapes that a user adds. I remember reading something about this in old
newsgroup posts, but I am not knowledgeable on the subject. Maybe someone else
can give a more definitive answer?

I tried something like this - I determined what the view frustum was, and then
IIRC did some my own home-brew insidedness tests.

Thanks BW.
I like that idea - using the cameras frustum shape for an inside/outside test.
Using the cameras' hither and yon planes for space partitioning. BSP?

In another age, long, long ago early in this century, Gilles Tran wrote
a macro doing just that. I have always used it since then. I attach it
here. I must have a demo scene somewhere too... I shall try to find it
tomorrow.
Note: The prefix GT_ is a code referring to the original author. It is a
way I use to remember who wrote the code ;-)

Thanks Thomas. Very nice - big help.
Objects not seen by the camera but reflecting in visible surfaces could present
a problem. I guess you could 'add-back' objects not seen but within a distance
of the frustum - if that object type was important to the reflections in the
view.
Mike.
