Ideas for interesting 2D effects?

category: gfx [glöplog]
In this day and age I find a lot of cool 3D effects are being made and I really like them. But once in a while a 2D effects sneaks into a demo and I find those awesome.

What are some fun and/or interesting 2D effects which fits our current technology?

just came across this a while ago: http://www.esimov.com/2012/02/organic-turing-pattern

i've a feeling i saw it on another thread on here. But anyway, interesting and 2d. Somebody make it cool and realtime :) (Or better still, 3D and realtime)

haha, right after posting that i checked out this prod. Fastest request -> implementation time ever :D

...and now i remember i saw that other link on the random WIP thread.

Here is a real-time sorta-turing pattern implemented with WebGL: http://cake23.de/turing-fluid.html

I discovered it yesterday. Stunning IMO! Looks like a giant soup of magic! When I find the time I seriously have to look into how those turing patterns work.

You can also play around on a 2D canvas and come up with an interesting effect of your own after a while.

Photon, I was figuring I would play around with some different stuff inspired from different ideas. But just starting out flat would probably be a little slow - you know, inventing the wheel and all :)

So I'd love to get some different techniques to google around for and read about.

Yes, it's time-consuming, and there's no guarantee an effect will look palatable even after lots of work, many ideas will be scrapped in the process. Also, only a few types of display work because of the way we're wired, anything but surfaces, volumes, contours, and basic geometrical concepts like lines and points becomes more, or less, pleasing porridge to the eye+brain. One very useful tip is that artifical lighting, even the simplest kind you could implement, will aid the brain in this respect.

Pure awesomeness!

I bet you could find a lot of inspiration at http://www.shadertoy.com

Unfortunately I can't go there without Firefox crashing.

It's true. Even in my new PC, with I7 and GTX660, the first screen tries to open too many shader at the same time. It doesn't crash, it used to crash,. but sometimes glsl.heroku is much easier to browser and enjoy. But good quality stuff on shadertoy, more categorized. Less copies of the same things as heroku.

Classic 2d themes can always be run faster, bigger / more entities

Cellular Automata, Fractals..

CA combined with Voronoi has been done a bit..

Give the brief I'd think in a more computer science/simulation direction

Feedback effects always have a chance of looking cool.

What is a feedback effect? Google returns a lot of economical articles.

Also, thanks for the all the suggestion. I feel I have some actual specifics to research now instead of just blindly searching around for "2d effects" :)

Feedback effect is when you use actual screen output as a input for the effect.

So currentframe = SomeNiceEffect(previousframe);

Like this one

If you have Winamp+AVS (or MediaPlayer) installed somewhere look at the effects, most effect use feedback.
