It's firefox, chrome/chromium renders them.

As always they were embedded with the link to the original svg-s;
they are hosted at ocal, with a thumbnail generated with inkscape.
See how they supposed to look when they are "stopped":





-as in this post-

This one is too much to render as an svg so ermbedding the still image instead:




And here it is how it should work alone:

-using the first one in the second row from the pack-

Very cool.  My old laptop doesn't render so well, (might do better if they were smaller),  but I really like these.  very imaginative and some cool use of colors.  The lightning turned out so well too, I can see that being used in Halloween stuff coming up.  keep up the good work.

Thank's!

Design-wise it's very limited what this kind of animation can cover -it was the exact same kind of "wavy" animation -using a hue rotate animation over a fractal noise and using that as an input for a displacement map.
Other limit is by the browsers rendering speed/flickering. Would need some research how to capture these animations to animated gifs.
Batik was mentioned by MC over the irc, haven't dug into it.


Newest pack -quick one, drawn within two hours-:



Edit:
Openclipart uses a previous inkscape version to generate thumbnails, so made an export for the intended look.
Issue is probably related to component transferring and the alpha channel.

Oh, I like those.  I'm always looking for a filter to add to a solid color, to simulate natural things, especially foliage.  But some could be used to simulate bark as well.

Oorr.....are those overlays?  Or like overlays?  You mentioned "painting".  I'm not sure what painting means in this case.  But that one where it's all gray, but still showing a bumpy outline of the coffee pot and apple and camera.  That one gives me the idea about foliage.  The last one gives me more the impression of tree bark.

Oh, the one right under the gray one, that looks very watercolory.

Off-Topic: show
With the amount of time invested in it's a bit of a bummer how these are misinterpreted. Maybe I should rather use these to create new images instead of sharing the source goods in packs.


By overlay you mean a filter that would affect the background image? That's better be avoided as it take ten time more resources to render. Practically it doesn't work.
Just add these to images with a nice colour flow in their fills -smooth transitions like gradients are preferred-. From that matter it works best with photographs.
I'm not sure what painting means in this case.
The output is intended to look as it was painted.
With oil on canvas or whatever, some have transparency/holes for the worn/weathered effect.

Here are some painting details for compare:

 




You are right, having looked for these reference images after, the brush strokes of the oil paintings are more evident in their details.
It's more of a gouache with dry brush then?



Would make a tree bark pack just for compare but now there are others in the same list -one that adds a shading like a bugs back, one that resembles concrete, some carving in filters, foliage (a newer this one) and tree bark.

I meant "overlay" like in the Filters sub-menu.  Not using an existing image behind, but just using a solid color behind, and the filter creates the effects.  See attached.

So for example, the first one.  To me, that looks like leaves scattered on the ground.  (called "Frost"!)  So if I made the background color something more like brown or golden, it might look more like leaves on the ground.

For foliage, I was think of something that looks like a tree or bushes from some distance.  Like in the bottom image you posted above, those trees.  So I might make a roundish object with plenty of randomness, color it green, and the filter would make it looks something like the leaves from a distance.

For bark, I have to admit that I'm a bit of an expert.  I hold (very dated) BS in Forestry 1980.  I've always wanted to make a photographic study of tree bark.  Unfortunately, I only recently got a decent kind of camera.  So don't have the energy to travel the country and collect photos.  It's just something I find very interesting - the variations among species, and even the variation on a single tree, varied by age.  Last years growth will be very thin, smooth, and greenish.  As we move down the tree, at older and older bark, it gets thicker, sometimes darker, and all kinds of variations.

But anyway, don't go to any trouble on my account.  There already is one filter of bark.  Not  ideal, but ok (looks to be some softwood or coniferous species to me).  So anyway, don't go to a lot of trouble.

Oh, I was thinking like "raster paint".  Now I understand better.

For the pointilism example - I couldn't say how many times I've looked at that image, over the years, but this is the first time I notice the monkey!

I see. For such an "emission shader" -kind of useage svg filters don't work so well, there are certain limitations of arealistic look. Stylized one, sure thing.

Anyway, another go at the organic looking:

Oh yeah, that's awesome :D

Why are there limitations?  (if it can be explained in a simple way)

PS - nice Norway maple leaf there (Acer platanoides)  (or some horticultural variety)  :-D

There are limitation of the complexity.
Even making as simple as a paper texture it takes compositing a flood fill into a fractal noise, some displacement and blending it with another flood fill.

For a layer of tree foliage, it would take to generate the "cropping" with a series of fractal noises not to make it look too obvious or at least to look somewhat similar to leaves -next to eachother with no overlapping.
Do the same several time, to generate the "shades" of lighter and darker ones and then maybe place them atop eachother?

No, that wouldn't be enough.
A tree is a "foam" of particles -leaf- within a more-or less spherical shape.
So, what would be the input for the filter besides the shape of the filtered object?

Some blurring added in to that to create a lousy 3D feel with diffuse lighting. That would only result in a single solid spherical shape with no depth.
So instead of generating a single 3D, first that would take to be cut to smaller chunks.
Twice, with inverted colour direction -as you can see through the first layer of leaves and see the "back" of the sphere from the inside.

Then, when all chunks are separated, could be breaking down the shading to separate generated layers of leaves.

Maybe the original fill could also add in an overlay effect -which would also take the ridiculous amount of compositing, displacement and tweaking to look somewhat conveying in the result.

All in all it's a bit more complex than a camouflage filter.

Well, maybe when I finally get around to learning how to make my own filters,  I will understand it better.  But in any case, it would kind of take the fun out of creativity, to have filters which give a completely realistic appearance.  I would be perfectly satisfied with either one of those last 2.  Well done!

Thank's!

Actually that's the same filter as before, just rendered with 0.92.
The colours are coming from the filtered object's fill mostly for the leaf pattern.

Making custom filters is not so complicated -only the gui is a mess.
