A single butterfly follows a spline curve through a marble tunnel.
If there had been three of these following one another, I would have had to bump
max_trace_level up to 8.

I like the butterfly. I'm working on a scene with a wind chime and thought a
bird or butterfly on the fence post might add a nice touch to my scene. How
did you make the butterfly? I downloaded a couple butterfly pictures to use
a an image plane in Wings but haven't gotten a good start with that yet, so
any deatails about you model/method would be appreciated.
Nice job!
Jim

Hi Jim, if you're interested, I've uploaded an .obj model that you
can play with and see how I did it in Wings. It's a very simple model that
you can do what you want with, but you'll see how I kind of drew the
patterns on the wings. It's based on a Peacock butterfly, and is good for
distance shots.

The butterfly is from a photo of mine in which I managed to carefully select
only the butterfly itself and then make everything else black. POV_Ray's
image_map syntax allows transparency. Here is how I did it:
box {< 0, 0, -.001>, < 1, 1, 0.001>
pigment {
image_map {
gif "black3016.gif"
transmit 0, 1
map_type 0 //planar
once
interpolate 0 //none
}
}
finish{ambient .5}
}

ah .... thought it was a model (casts shadows) but i see that transmit 0,1
handles the black area .... thanks

Why the spline curve? Are you planning on animating the little guy??

Definitely, in fact the image is one frame from an animation. I have done a
number of animations which involve butterflies following spline curves. I
sometimes, as in this image, use a union of cylinders and spheres of some
suitable radius, following the spline curve, and subtract that union from a
large sphere or cube, creating a tunnel or tunnels leading in and out of the
sphere or cube. Then I fly the camera through the tunnels and often the camera
is following several objects. Perhaps one or more butterflies.
I have found tho that I must take care to have many many frames or else the
action happens too fast.
Hence, once again, I need a render farm.

:) No problem. Take a look at the underside of the wings, that's what the
top side looked like before I played with it. It was really a matter of
using 'bevel' a lot, deleting certain verts, and then adding certain verts
and then 'connecting' them in a logical manner to get the desired result. I
use this method fairly frequently, and it seems to work well so far. Have
fun with it. :)
