What is the best way to create shapes and scatter them randomly on the texture, as in that well-known "cereal killer" cheerios in milk texture (sry, can't find link even though I know the name)
I could find one and take a look at how they did it, but what I am after is the best way to execute this effect. Thanks. |

I think the "best way" would depend on filter specifics. I've seen it done differently in different filters, and what works really well on one may not work at all on another.
Like scattering raindrops vs. scaterring cheerios vs. scaterring dirt seem to be done in different way, and each one works the best for that particular scattering style. Is there a specific filter you're working on? |

if i remember correctly, the cereal filter isnt scattering. it simply 'grows' the individual cereal objects from a 'cells' component. the cells are already in the component.

Still looking for that "best way." I made one filter ("Scatter selection") that keeps copying the original image over and over, doubling the number of objects each time. Gets rather slow after a while. I just made and submitted a different approach ("Multireplicate") which works to create a larger number of objects and allows for more variation, scaling, rotation and color shifting the copies. Still rather slow but if you need to make a couple hundred copies from a single object, it works nicely. I'll put up some samples.

Here are two examples with the new Multireplicate filter: A flower garden from a single flower and good return on a one-euro investment. Backgrounds were created separately.

and ya know, i think someone else did one of these a while back. the coins picture is stirring a memory here. If wishes were horses... there'd be a whole lot of horse crap to clean up!

Oh, I better go fix and resubmit this since I already advertised it. Came back to me for being too slow to render.

I revisited this filter, making it slightly faster. Let's see if it makes it through the submission queue this time.
It still competes for the status of The Slowest Filter in Town. |

In the meanwhile, here's another sample. I took my Leaf filter default and ran it through Multireplicate for foliage:
With all settings maxed out (number of duplicates, antialiasing, shadows on, etc.) this one took 9 1/2 minutes to render. Still beats doing it manually. |

it's seems pretty fast - 42 sec using the default preset settings - I'd hate to see what you think is slow   |

Approaches 10 minutes on my laptop with "layers" at max setting, shadows on and antialiasing all pixels 5x5. I've managed to make a couple of fractal-type filters that run about 30 minutes...  |

Just came up with an interesting -- and a very fast -- variation that could be useful for some scenarios: Cellular Tiling.

thanks, TD
i like the multireplicate better. that cellular one doesnt seem to overlap and cover. If wishes were horses... there'd be a whole lot of horse crap to clean up!

Hehe -- madness continues: Each image individually scaled, still renders in a couple of seconds.

Correct -- it isn't multireplicating the entire image, but placing it into every cell. But there are things you could do with it. Imagine, for instance, making just one radial crack and duplicating it into every cell. |

Some mod thereof could also enable making seamless patterns from just a tiny image, for the method (sort-of) centers the image in each cell.
Come to think about it, if you shrink the original image more and overlap four (or more) of these with masks, you can make it very close to the original multireplicate. Runs off to try this... |

That approach has some potential. It's not perfect, but it runs 4X faster than my last Multireplicate.
And the scattering pattern is way more natural. 
Ahh, them falling leaves, snowflakes... |

So, here's the million dollar question: can I rotate each one individually...?

Rotation would be handy in some instances but would be best left as a switchable option. More layers so as to be able to achieve full coverage would also add to usefulness. And definitely a switch for the size variations so that same size could be maintained when needed.

hehe, TD, you ticle me. you remind me of me in my early days
and yeah, i like where you're going with this.
just a thought here, because of a perceived similarity, try dilla's smiley face filter... open the guts and see what he's doing to replicate there. If wishes were horses... there'd be a whole lot of horse crap to clean up!

This be good.
Every instance is individually transported, scaled and rotated and it is still relatively fast (emphasis on "relatively").

Not only that, this render is as fast as the previous one.
Yes, it is chopping off quite a bunch of them, but that might not matter if it was a pile of leaves or other somewhat irregular shapes. |
