Hi!
I am relatively new to these newsgroups, so this is the
first picture I post here.
My desire was to make smooth bumps on a sphere with
a non patched POV.
Lately I have played around with trigonometry, CSG
and some of the basic shapes in POV.
This picture is one of the results from this experimenting.
Please comment on it.
I'm not at all good with pigments, textures or light settings.
Any suggestions for a better POV-scene with this shape?
Would anyone be interested in a macro that make these
bumps?
And what about other similar macros?
(E.g. outward bumps or inward bumps with smooth
outward edges.)

What, no checkered floor? ;-)
I like this - are you posting the code? Can the macro be applied to other
shapes or just spheres?

No kidding though, with a checkered floor, this would be a great
variation on the recent flood of interpretations of the traditional
scene.
is that a run-on sentance? :)

Thank you
I'll post the code to p.t.s.f soon.
I just have to tidy up my messy code a bit.
It hasn't become a macro yet, Because I have some thinking left to do to
make it a macro that is "thoroughly useful".

Accidentally I hit one of the control keys together
with the return key and off my last post went before I
had finished it.
(A "feature" in Netscape messenger I think.)
I was about to say that the code I used to make
the bumpy sphere is best suited for spheres.
For making bumps in planes I have made some other code.
The reason I asked about anyone being interested in
such macros is that that would motivate me to write
them sooner.

What do you mean? Do you really want one with a checkered floor???
Well then; how about a floor with smooth up and down CSG-bumps in a
checkered pattern?

Looks real good, I'd guess you used a sphere, a cone and
took a torus away from it and then took the resulting
object away from the large sphere.

Yes, you got the general idea.
And that's the way I would prefer to do it
(making only one last cut from the sphere),
but I haven't figured out the detailed CSG
for that yet! :)
(For me it seemed a bit complicated, because
the top of the cone has to be tangential to
the sphere. An because of that I was afraid
that the cone would leave some tiny leftovers
near the edges of the bump.)
I posted my code to the povray.text.scene-files
news group.
(My bumps are placed in the middle of the
pentagons and hexagons of a Buckminsterfullerene.
And because I was to lazy to calculate the
positions of the bumps and then paste them into
the source code, you will also find the
co-ordinates for a whole such "Buckyball" in
there.)
