Short:
I'm searching some nice images, where an ISOsurface is the
main object... It'd be nice, to have the image as well as
the function for the ISO ...
Long:
I have to hold a paper. The seminar is called "Geometric Modelling"
and I have to talk about "Complex Surfaces". So what am I gonna do?
I'll show them the principal of some simple UV-Surfaces, and how
"normal" 3D-Packages will do when tesselating, but I also want to
show how nice it can be, to have a really complex object, described
with a "simple" function and be rendered without triangulating...
So I'd like to show some stunning images with a nice scene setup
and lighting and then only the ISO in a 3D-Grid, rotating and also
showing the function (maybe explaining this) ...
Has someone incidently lyning something like this around, and
allowing me to show this in class ?

Jan, I'm not sure if any of my isosurface images will
fit into the categories that you describe above.
But if you do want to use any of them in your seminar,
then you're welcome to do so.
If you want the source code for a particular image, just
tell me and I'll see what I can find buried in the mess
on my HD.
Below is a list with links to some of the isosurface
images that I have posted to povray.binaries.images.

Thats very kind of you, thanx very much ..
Here are the scenes, I'd like to use, but
especially with the "old" Megapov ones I've some probs
porting them to a "usable" 3.5 version ...

I'd like to see the source for this one as well...

I'd like to see the source for that scene, so I could render some
different views ... and of course, the whole thing without
any texturing/lighting

I can't get this to work with 3.5 syntax ... I tried to adapt
with what I thought will be the right function, but the resulting
image is quite different ...
The semantik of the old megapov if()-function and the 3.5-select() one
are comparable, aren't they ?

OK, I'll start some archaeological excavations then.
And then I'll see if I can find time for some rewriting.

Sorry about that. I'll dig it out of my job PC tomorrow.

I think that I have v3.5 versions of the scene files
above stored on a PC that I probably will not have access
to before friday.

I have just posted a v3.5 version of this scene to
povray.text.scene-files:

Yes, they should be comparable, but I don't remember if
the order of the arguments are the same.

Well, first, it is "isosurface", a single complete word...the "iso" part
is not an acronym. I don't know why this pops up so often, but it is a
pretty common misunderstanding.
There should be plenty of raw material on these newsgroups, and the demo
files for 3.5 might give you some ideas. I don't know if you could
legally use them directly, though.

in general if you plan show how isosurface modelling can be easy navigated
with smart macros then iso_csg library by Chris (and partially by me) is good
example

- I hope you make it !
(It took some time to find the right files and to clean them up.)
The source code for the last image (Iso-bonds again) is now here:

It will be interested to see this.
