Probably because everyone thought you could search yourself... :-)

as far as I understand it, this is for creating pattarn basing on object.
It doesnt allow i.e. to take hexagonal pattern and blur it to get a 'gird'
with soft half-tones. Using function can do it (for monohrome patterns)

this looks like this wat I suggested , but it's a path
Is there sens to make better version of my blur (gauss), or should I rather
wait for author of path finishes it (and maybe include to new PovRay) ?

Well, that thread was much more specific so nobody mentioned it, but if
you are interested in pattern/pigment blurring in general you could have
searched for it.

I just meant you might want to have a look how it's implemented there,
esp. the difference between my and Chris Huff's approach.

You could use 3 functions, one for each channel, and combine them using
an average pigment of 3 pigments. That would get you a blurred pigment
at about 1/3 the speed of a blurred pattern. Using an average pigment
would probably be faster. The only way I can see to blur a texture is to
use an average texture or write a patch.

Some work on that has been done, search through the older messages on
these groups.

I don't see a macro anywhere in that code. Your function is "parsed"
once, running through the #while() loops, and then executed whenever it
is called.

One of my posts further into the thread was about generalizing it to
work for any pattern. It isn't blurring textures, but neither is your
approach...it is just blurring the pattern.

The main idea of that patch is to make a "smooth" blur effect that would
be suitable for isosurfaces based on the object pattern. The proximity
pattern was too slow, and other blurring techniques result in a
"stepped" pattern instead of a smooth variation. The method I used was
sort of like a voxel map created on the fly and blurred/interpolated to
give the final blurred pattern. I haven't done any work on it lately,
but I haven't abandoned it either...I'll probably do some more
experimenting with it when the 3.5 source is released.

Not sure what you are asking.

I have mentioned my blur/proximity solution in one of yours threads so you
should know it already.

No. It is basing on object patter but it is not limited to this pattern.

I use functions so I assume I can take hexagonal pattern and blur it :-)
