If you have a proper inside vector you can bend mesh2 objects with the approach
by Chris Colefax. In this case, mesh2 objects can be handled like other CSG
objects (spheres, boxes and so on). I have done this with my snails
(http://www.tc-rtc.co.uk/imagenewdisplay/stills/index345.html) which consists of
a mesh2 object and a blob with thousands of components. In fact I did not
understood Chris's parameters and wrote an own approach, but very similiar to
Chris, since I judged it easier to implement it by myself than to understand his
parametrisations.
@Thomas: The Mud Maid at the "Lost Gardens of Heligan" (I spend my holydays this
year very close to this garden) is a sculpture consisting of mud, clay, cement,
gras, ivy and moss and she is laying at the left side of her body to the ground,
so no much grass at the left side if standing;-)
Best regards,
Michael

Not sure, but I think that /bending/ an object will be much slower to
render, especially if there are 15000 of them ;-)

Ah yes, the Lost Gardens! I unfortunately missed those when I stayed in
Penzance many years ago. Only much later I heard about them. I hope
/your/ Mud Maid will make it here or perhaps at the TC-RTC.

Yes, indeed, the rendering time is heavily increased with this approach. The
only option to reduce it a little bit is to give proper bounding boxes
(bounded_by) since bounding with csg-differences or -intersections are not
implemented as one would expect in POV. But I think this would be a very hard
job, and so I can understand, that this issue has not been addressed so far.

I really hope that this WIP will make it to the contest. At the moment I have no
idea to link my imagined image to the topic. May be the Men-An-Tol as a stargate
at the background, just to keep it cornish.
Best regards,
Michael

This one is very credible! It needs only some animals, now.
Are you starting a new image for the POV-Ray Hall of Fame?

Thanks Paolo, I am quite satisfied too :-) But it is far from HoF
quality and I guess my work in general generally falls short of that
too. It is not my aim (as if it were me to decide ;-) )

Much better than my attempt of (my god, i'm getting old) seven years
ago. I didn't dare to choose a close camera point at the time.
(The image is of course an illustarion of the glycocalyx, although I
don't expect many of you are familiar with that. It is the layer of long
proteins on the inside of bloodvessels that for a sort of gel and
protect the bloodcells from colliding with the walls.)

Well done.
Friesian cows I assume. But why?

Oh! I remember that one! A humoristic approach to Waterland indeed. ;-)

to emphasize that the scene in the glass container is in fact microscopic.
