Hi there,
Last week, the heise newsticker had an article[1] about the
superformula. It is told that using this formula, you can describe
(almost) every thinkable shape with only a few parameters. Well, they
had a link to a site[2] where you can download a tool to play around
with, and even export a mesh to pov! I couldn't resist and now I think
I would like to share this with you.. even if only the rendering is
done in pov.
There was also someone who implemented the formula in pov[3],
dynamically generating a mesh. I didn't try that yet.
Ah yes, I was so stupid to not store the parameters to the formula for
this object, sorry ;)
Greets,
Dave V.

This isosurface should handle the 2D cases of the superformula as
described in http://astronomy.swin.edu.au/~pbourke/povray/supershape/
//---------------------------------
#declare m = 7;
#declare n1 = 5;
#declare n2 = 5;
#declare n3 = 5;
#declare a = 1;
#declare b = 1;
isosurface {
function { pow(
pow(abs(cos(0.25*m*acos(y/sqrt(x*x+y*y))*abs(y)/y)/a),n2) +
pow(abs(sin(0.25*m*acos(y/sqrt(x*x+y*y))*abs(y)/y)/b),n3)
,1/n1) * sqrt(x*x+y*y) - 1 }
contained_by { box { <-2,-2,-2>, <2,2,2> } }
scale <1,1,0.001>
pigment { Yellow }
}
box {<0.01,0.01,1>,<-0.01,-0.01,-1> rotate<0, 0,0> pigment {Red} }
box {<0.01,0.01,1>,<-0.01,-0.01,-1> rotate<0,90,0> pigment {Green}}
box {<0.01,0.01,1>,<-0.01,-0.01,-1> rotate<90,0,0> pigment {Blue} }

This looks like a fun tool.
export of attached shape to pov mesh turned out to be 3228 kB

Hi there,
Hi Dave
...Well, they
had a link to a site[2] where you can download a tool to play around
with, and even export a mesh to pov!
How are you opening this tool?
I couldn't resist and now I think
I would like to share this with you.. even if only the rendering is
done in pov.
?????????????!!! ;)
Ah yes, I was so stupid to not store the parameters to the formula for
this object, sorry ;)
Ah, you'll find them again, or at least get close.

Unzip, run the .exe file ;)
Be sure to get the 3d Shape explorer, not the illustrator plugin.

the tool supports exporting to povray.

We will see..
see you

Oy, yet another object I wouldn't want to be hit in the head with.
Very nice!

Thanks for the tip. Do you have to register to get the export to POV
feature? Otherwise, how to?
thanks,

Yes, although the POVRay scripts work as well but it takes longer
to experiment to find the shape you want.

The version you see there is the MSWindows one, if you want Mac OS-X
or Linux version see my www site.
