I need a bicycle model to do an image for a friend's bicycle club
(non-profit). Does anyone have one they can share?

If Dan Connelly is still around, he might be able to help you out. The
email address on his web page is djc### [at] flash net, and you can see his
bike at http://www.flash.net/~djconnel/POV/bike.jpg but unless I'm mistaken,
he hasn't posted here in a very long time.

Thanks. Waiting to see if the email bounces...

What kind of quality do you need? I have a mesh of a street bike but
it's a little rough...

Um... at this point? Any quality as long as it looks like a ten speed
bicycle at 1280x1024

I'll zip it and sent it along and you can decide for yourself.
Look at the bottom of the file for the object parts and textures.
It's ready to render but I never did do more than take a look at
it to see if I liked it.

Anto Matkovic has an sPatch bicycle model for download on his site. Click
on the frog to get to the models page:

Giving up on most of the available models I am attempting to model a
bicycle in MegaPov myself using isosurfaces for the frame. Unfortunately, my
idea about blobbing cylinders is not working too well, because when you
create a simple cylinder at an angle, it is somewhat flattened in one
direction.
Is there a good way to rotate a function in isosurfaces before you blob
it?

Sorry, here is what I am using now... I suspect I will need to make my
cylinders differently so that their end circles are tilted correctly.
#declare R = 0.25;
#declare C1 = function { x*x + z*z - R*R }
#declare C2 = function { y*y + z*z - R*R }
isosurface {
function { C1(x+y,y,z)
* C2(x,y,z)
- 0.001
}
method 1
accuracy 0.001
contained_by{sphere{0,3}}
pigment {rgb .9}
finish { ambient 0.25 }
}

Hello Bill,
Making the bicycle frame with an isosurface
is not an easy task, but the code below may
give you some hints.
(Note that I'm not sure if the possibility
to treat functions like I do below was
provided intentionally by the authors of
MegaPOV.)
Best regards,

Those lines help me to see when I have reached 72 characters per line
and
thus when I should hit the return button. If I don't, the code will wrap
to
the next line if I post the code to this news server (at least for me
when
I'm viewing it)

Yes, it did, thanks!
But... why don't -I- have MegaPOV 0.7? Last I heard 0.6 was the newest
version.

Version 0.7 has been out since February 5...

Don't you have an editor that takes care of this automatically?
External editors such as Vim and Emacs can do that easily,
Netscape's built-in editor, too.

Well, that works fine with text, but with code it might wrap where you
don't want it too, and it destroys indenting.

Hello Adrien.
I really love Emacs, but I'm POV-ing in a windows environment
these days (using POV-Ray for windows).
And therefore I use POV's integrated CodeMax editor, which
allows for far more than 72 characters on each line.
(I don't know if there's any way to limit it's line length.)
I also use those "lines" for separating the different sections
in my code, so I would insert several "separating lines" manually
anyway.
I could probably make a setup with a windows variant of Emacs
with a POV-mode, learn it some anti-line-wrapping tricks,
make it start POV-renderings when I hit e.g. a function key
and have it load the image into image viewer after the rendering.
But: I'm quite satisfied with the CodeMax editor so I probably
won't do this before I'm leaving MS Windows for a (L)Un(u)ix
environment.
