Game of Life
I'm not sure if this would be possible, but has anybody ever see the game of life? Basically ever pixel is considered a cell and each cell is surrounded by 8 other cells. If there are 2 or 3 cells alive around this cell then it becomes alive. If there are more cells alive than that cell become over-crowded and dies. If there are less cell than that cell becomes lonely and dies. I don't think this would be possible in AVS but it might prove to be an interesting preset. Then again I dont know how to use the convolution filter very well so maybe someone could exploit that... Any ideas?

I have heard of the Game of Life, the one that has you spinning the little spinner to try and make it through life to retire, but I have also heard something like this before. I think a preset was made that was something like this, I can't remember exactly, but I think atero made one...
As far as I am guessing that a condition or something is missing, or maybe I am am just misunderstanding something, but how would and "cells" come alive in the first place?

Atero has done several cellular automata, including Life I think.

Damn well there goes that idea. Anyone care to provide a link to some of these presets?

I might as well just ask here too. Anyone know of any fractal presets? I would imagine creating a mandelbrot fractal in AVS would be quite the challenge if it's possible.

Fractals have been done a *lot*.

Escape-time fractals with constant formula (Julias) can be done through a dynamic movement. Mandelbrots are much harder (but of course possible) and wouldn't be animatable much.

Superscope dot/scanline renderers can do pretty much any fractal slowly.

IFS fractals are easy too, usually a highpoint scope is used.

The hardest are L-system fractals that depend on abstract entities such as lines. We'd need variable sized arrays for that.

I recently used another way of doing a sort of l-system like fractal:
http://www.acko.net/dump/ifs.avs
http://www.acko.net/dump/ifs.png

It starts off with a ^ shape and then uses two additive DMs to change it into _|¯| (move and rotate each copy 45°). By repeating it, you get a nice space-filling fractal.

By definition a fractal is any infinitely detailed, self-similar shape, which is very easy to do in AVS with a simple movement and a constant Renderer. It's tricker to recreate some of the more well-known fractals, but not impossible.

Heh I just figured out why my IFS fractal wouldn't converge on the dragon IFS (as it was intended to do).

There are two ways of aligning each ^ in the _|¯| shape (due to symmetry).

By flipping the sign of the terms in the x= statement in the DMs, you can explore the other ones.

There's the dragon IFS, a dragon-ish IFS, my original spikey IFS and a spacefiller that converges on a triangle.

Here's the real dragon:

so fractals are done...

golden mean?


dont know how you would make something really graphical with it but I'm sure there's a way. and it's probably been done!

if you get an idea in avs, chances are, it has been done before, probably by UnConed, or it is impossible.

:D

Atero did Conway's Life, as well as several other automatum, with some very clever use of the the convulation filter and color clip.

Fractals have been done by nearly everyone, standard fractal presets have been done be unconed, atero and undefined to mention a few. Many other presets use fractal theory dm's to create more general effects.

Phi and the golden mean has been overdone, jheriko and atero both did presets centered around the golden sprial, and many others have done 3d shapes that make use of the golden mean.

these days, you have to get REALLY creative to find something that hasnt been done 10 times over.

The best you can do is to make the old ideas better :)
On the technical side there seems to be less original ideas left to do, but on the other side of the town where i live there is more room to play with.
Presets don't have to be the model example of technical excellence, but you can try to make something new in concept or try to make some really good & fresh looking stuff with aesthetics/design.

I found Atero's life preset in my AVS dir ;) (have waaaaay too much presets here) in case you're interested.

UCD, could you upload your entire crowded avs folder somewhere, please? I've never really been collecting stuff. Now i feel sorry for that and collecting everything from the forum threads seems to be a shitload of work.

Errr not really, it's not that big really :P. For sure not much forum stuff in there.

Search the forums for 'attach*' ?

Hmmm damn it.
Anyone in here having a huge almost complete avs collection from the past 2 years?
I'll provide space for uploading if you don't have any.
