uberBlend - (This changes everything)

Could you upload a demo filter that you would like to use that uberNormalWithAlphaBlend on?

It won't make my fumbling in the dark any better, but will give me a direction maybe

40 iterations...

6:47 to render

Wait in line mister! FF employees are on my case now
I'm talking about this thread:
http://www.filterforge.com/forum/read...MID=103591

My first try with uberBlendStar

The first one I made took me more than 10 minutes. But had to reduce at 5 samples, so it tokk me for this one 3 minutes.

I would loke to know how to use the components in this filter. Which components we can change and we do not have to touch. where we can add controls and where we do not have to add some. Well, a tuto would be nice. Please...

Gislaine, you can replace the shape and it's connected thresholds with whatever you want (at the top of the filter).
Try for example to put a star with transparent background and red with 25% alpha as foreground. Just skip the thresholds.
You will see how the rest of it updates.

Basicaly what happens in the filter is this:
You give it a shape or something to chew on. It makes a matrix of small copies of that shape. Then it transforms (rotate for example) each of the mini copies a little different. Now it makes the shapes big again, so naturaly you can only fit one copy at a time in the window. Now the script does it's magic - It takes each one of the copies in the matrix and blends it with the ones before it.

The itterations is the number of "steps" or samples to blend.
The blends modes are:
1 = normal (Like multiblend)
2 = darken
3 = multiply
4 = lighten
5 = screen

I'm not infront of the filter right now so I don't remember what other controls you have...

Going for a 3d-tunnel effect, sort of lame...

Component still grabs from right-to-left which is the opposite of what I originally wanted

What do you mean?

get that blendmode selection out of the inner loop and gain some speed Since the loop code is very small, you can easily do it like this:

Code
if (BL_MODE == 1) then    while ( i < count ) do       ri, gi, bi, ai = get_sample_map(i + x, y, SOURCE)       r, g, b, a = blend_normal(r, g, b, a, ri, gi, bi, ai, opacity, hdr)       i = i + 1    end; elseif (BL_MODE == 2) then .... end

Remember that this is the innermost parts, getting called w*h*aa*loop count times, so you want to get as much outside the loop as possible

Very well done Ghislaine on the example you have put, I like it much, is elegant, balanced and moving. Well done



Also like much this one from uberzev

Uberzev, is this what you mean right-to-left or left-to-right?

Check out the new control I put, called "LTR \ RTL".

I rewrote the script according to what Sphinx said while I was at it Thanks Sphinx.

uberBlend LTR_RTL.ffxml

Correct

Glad I could help

had the same notion but had left it out since it added complexity to the code

Just thought it would save you some time

Out of curiosity, what are you gonna do with the LTR? I thought it would be useful as a user option since different blends have different reseults with and without LTR. Can you tell me, or is it gonna be a big suprise in your next filter?

Simplified your method a bit

LOL, I was so into adding it as a control that I missed the obvious!

Actually it looks like I messed things up! Results are now flipped horizontal!

(Didn't notice since I was using a symmetrical star to test with... )

correct code appears to be...

Code
get_sample_map(count - i + x - 1, y, SOURCE)

Heh, I was wondering what the "count - x" is all about

Nice examples. In the FF example I like the right F better.

With source image

Like and love much how you have applied a source image to this. Great



Well done this FF effect, it looks very good and interesting if you can define the base shape.

and making a full circle with 21 iterations and Shrinkage value zero

A spirograph black hole that sucks all the graphics

The star circle

15 iterations and Shrinkage value zero

And joining both parts

Cool stuff, SpaceRay!

I see Spiroman has struck again

Is that what you want Spaceray ?

If yes, I'm working on this uber's filter and I'll upload it when finished.
