We are pixels (Read 1712 times)

GianCarlo Junior Member Offline Posts: 78 Italy	We are pixels Feb 20^th, 2009, 4:48pm http://www.openprocessing.org/visuals/?visualID=1053 A text made of moving Particles. Use the key 'A' to create the words "Hello World. We are Pixels." Mouse click to move Particles to another place. It is pretty basic, just an investigation on how to get coords and colors of pre-existing pixels. Hope you like it. GC

Lovely! This has turned out to be a very useful starting point for a performance animation project I'm working on. I worked on the code... found some very significant optimizations that make it fly quite nicely at 640x480 so it can display fullscreen. It also now refers to an offscreen buffer for the swarm to refer to. Check it out:

Thanks Giancarlo!

It has a bug tho. I'm glad you found the skecth useful for you. Cheers GC

I've cleaned up the code and posted it on the same page.

things added you might find useful:

a technique that shuffles the pixels to be inspected in the offscreen buffer to evenly distribute the particles across the whole screen. this way you never seem to run out of particles, but rather they get more thinly distributed,

use of a timerTask to schedule a recurring task in a predictable interval

use of loadStrings to make use of a text file to use as source typography to swarm around. this makes for a more generalized approach to rendering streams text.

attaching a graphic image to a particle to animate it. the particles being attached to are changed perodically, giving the impression that there are more textures in use than in reality.

Enjoy!

Kenneth.
