Filters in action, filters in pack

[Lazur]

This one is "filter in action".

Got sidetracked with descriptive geometry.
Had modified the render 3D polyhedron extension to have it 3 digit input for the rotation values, set it so a rendered cube's axises were at exactly 22° and 40°.
Then the original idea was to map ellipses with their axises right to the faces, sort of like with the Rytz-construction, and then came this which is more of the result of simply affine transforming clones of the parent cube.

Well, I don't understand the math part.  But it certainly looks interesting!

[Lazur]

Following the previous offspring of cubic idea.

[Lazur]

More filters in action.
Revisited the plaid filter concept as before.
This time a displacement map is added and also the shading is affected by the original tones.
Not completely happy how the skin turned out as it has less contrast compared to the unfiltered one, but didn't want to tweak-troubleshoot the component transfer...

[Lazur]

Some recent "in action" works. Sloppy as it can get, just playing around with the image filter primitive.

[brynn]

Wow, those are amazing!

I'm afraid to try and open one, since this computer is on it's last legs (and the images load slowly, so they much be large).  But when my new computer comes (Friday) I should be able to handle these.  (8 big GB of RAM with space to expand to 16  )

Another test image on the image filter primitive and compositing. This time in a similar use to this one.



1428 lines define the filter in the defs section of the file, took quite bit to edit this together.
On the top half you see the source squares next to eachother, producing the rendering gap of "anti-aliasing",
while at the bottom there is one object filtered based upon them.
Each object is pulled in with the image filter primitive and compositing is used in arithmetic mode to build up the alpha values.

To test out the idea in action.
Probably it's not the best theoretic solution because where two object overlap a different colour is rendered.
Instead it would need a bit more separation between the objects and their alpha/transparency values.

[Lazur]

Back to the beginning, sort of.

Pencil strokes -this time, by using lpe-s.

[brynn]

Nice!  Those look very real -- pencilly.

[Lazur]

Thank's!

The lpe-s are not that handy though. They generate too many nodes which slows down the working and doesn't have a dropdown list as the filters to apply the same setting on other paths as well.

Recent pack of simple turbulence:

Some of those put me in mind of 60's black light posters!

[Lazur]

Will get back to it. Have some ideas with the previous pack. "Work in progress"...

Until then here is a quick one, trying to mimick fur textures:



 

[Lazur]

Before revisiting that 60's filter pack, generating a variety of different fades between two flood fills;
duotone pack.
Flood fills can be changed at once by notepad++, by replacing the rgb values.
Definitely will make it with the mentioned previous pack's 64 pair of colours.
Also have the idea of combining it with turbulence.
Well and putting it into a kaleidoscope and animating the turbulence's values...
anyway, this is how it looks now:

[brynn]

I'm curious why you're using the checkerboard background.  It's one thing I've always liked about Inskcape, is it doesn't use that checkerboard to show transparency.  Any kind of solid background makes it easier to see.  Imo, a solid bg would "sell" your filters better.  Unless I don't understand something....

You've been doing such fancy stuff lately, that I don't always understand it.  When would someone want to use one of these filters, instead of making a gradient?  What is a good use case?

[Lazur]

Using checkerboard because if you open the svg with a browser white gets rendered behind.
No good for showing semi-transparent gradients, especially if one of the colours is white -as on its original.

This filter does not produce a gradient, but maps a gradient on the object.
Only the base square has a black to white gradient fill.
You can use it to make images have a duotone look -as with that mentioned 60's pack.

[Lazur]

Strangely the previous filters were a bit off. Somehow the checkerboard shows through slightly even on solid areas.

Here it is a different approach solving that issue:

[Lazur]

And finally, could finish these duotone packs to a megapack:

[Lazur]

Let's see how two duotone shaded copy can mix -previous filter in action:



Original, colourful image is here.

[brynn]

Wow - interesting - big shortcut!

[Lazur]

Newest one, "duotone filtered" turbulences:

[Lazur]

Now, to post those turbulences in the 64 sixties colour set:

[Lazur]

For the 0.92 about screen contest, just finished this:




"Filter in action".
Uses the new blending modes, use 0.92 to open it.


Edit:
By second look the shading was off so tried tweaking it a bit:

Third variant:

Recent stuff.

Inspired by that old topic, made some wallpapers with a turbulence based filter.

Some of those thrown into a kaleidoscope:
