Attached images show characteristic of function in pure iso_csg (sharp.png)
and in modified macros/functions (rounded.png) posted by me in
povray.text.scene-files recently. As example I've converted chars.inc CSGs
from standard distribution. Both images are interesting IMO but what do you
think about it ?

btw: anybody interested in iso_chars.inc include file - compilation of
iso_csg.inc and chars.inc ?

Sadly this rounding does not work for intersection/difference...
BTW, it would also be neat to be able to use arbitrary metrics like in the
crackle pattern. Right now these are 'metric 2' and 'metric infinite'.

Sure, i was planning to add some of the standard shapes from 'shapes.inc'
too, having the characters would be nice (especially since you can't use
text objects in iso_csg)

But I think they look more "friendly" :-)

doh, this sentence is above my knowledge :-(

I'm testing another neat idea currently and I'll finish and upload iso_chars
after that.

It's fairly simple in fact. You use the f_r function to calculate the
distance which is our common metric:
distance = ( (x1-x2)^2 + (y1-y2)^2 + (z1-z2)^2 )^(1/2)
the '2' is the reason why this is called 'metric 2' in the crackle
pattern.
When increasing this value the function is approaching:
distance = max(abs(x1-x2), abs(y1-y2), abs(z1-z2))
Which results in the way my original macros work.

I can't figure out how you accomplished the rounded pattern.

I've just used macros I made and posted recently in povray.text.scene-files.

I guess I need to take another look at those. I saw the object stuff, but
missed how the pattern can be rounded.

A sample for using iso_csg in patterns can be found in the iso_csg
package.

Spacey :-)
Somehow reminds me of a Spice Girls video.
