Just another mcpov render. This is after 8 hours of rendering. Flowers and
mantis modelled in A:M. The grass uses the countrygrass macro by (?)...I
have a countrygrass2.inc by Tony Bennett but can't find the author of the
original.

Nice render though.

In addition, praying mantises (at least the big green species) _appear_ to have
a tiny black pupil in their compound eyes. This is obviously an optical
illusion of some sort, but I've seen it in many images and videos.
Is there a story behind the immature insect?

I never thought about this before, but when I wrote my post, I wondered, "how
can they see if their eyes are covered by opaque green stuff?"
Heh, the answer is quite simple, and is also the explanation to that optical
illusion: Insect eyes are built from tiny facets, each of which receives only
light from a particular direction. Likewise, you can only look "into" a facet
from this very direction. From any other direction, all you will see is
structures that prevent light from entering into the facet - by absorbing the
light, and/or scattering it back outside. In case of the mantis, these are
obviously of the same color as the rest of the insect's body (though that's not
necessarily the case for all insects; e.g. some flies have distinctively red
eyes though their bodies may be brown or black otherwise).
In POV terms, this screams "aoi pattern" (needs MegaPOV though).

If I am correct, that is pigmentation.

Among other things, Cousin Ricky saw fit to write:

I have seen it in real life, in the big green species and in the big
straw-coloured variant (I think it's /Mantis religiosa/ around here). It
gives you an uneasy feeling, not only they move their head, but it looks
like they are always looking directly at you.

I modelled the mantis without wings because it was originally intended to be
one of those orchid mantids...the pink ones that live in flowers. That is
also why it has the wing-like things on the legs. However I went with green
for the texturing so I don't know if there is a mantis that actually looks
like this in the wild.
The eyes do need some work

Since mcpov is a patched MegaPOV the aoi pattern is available. Giving it a
try right now...seems to be working but it is hard to tell at this point how
good it is going to look.
