November 30th, 2008

Here we are, a small group of freaks travelling to Adobe MAX Milan in a special bus connected to internet and lot of entertaining stuff.

Pixel Bender 2. - filter ve Flashi

November 26th, 2008

V minulém díle (http://tom.krcha.com/pixel-bender-1-uvod/) jsme si představili v kostce jazyk Pixel Bender. Vzhledem k tomu, že je již konečně ke stažení CS4 Trial a všichni si jej můžou vyzkoušet, přešel bych rovnou k věci, a sice aplikaci Pixel Bender filtrů ve Flashi 10.

Aplikace, kterou si dnes vytvoříme je zde.

(MusĂ­te mĂ­t nainstalovanĂ˝ Flash Player 10)

1) Stáhněte si a nainstalujte Flash CS4 z www.adobe.com/cz/downloads/

2) Nachystejte si nějaký Pixel Bender filter (viz. inspirace v minulém díle)

Ideální však bude použít nějaký pokročilejší filtr. Já jsem zvolil twirl.pbk - příklad, který se nainstaluje s Pixel Benderem. 

- Otevřete twirl.pbk v Pixel Bender Toolkit

- File -> Export Kernel Filter For Flash Player … uloĹľte soubor *.pbj - pokud nastane problĂ©m pĹ™i exportu*, odstraňte nÄ›kterĂ© nepodporovanĂ© části nebo pouĹľijte mĹŻj vyexportovanĂ˝ twirl.pbj. 

* Flash Player Pixel Bender Runtime nepodporuje všechny možnosti jazyka Pixel Bender (např. blok needed) - o těchto možnostech si řekneme v dalším dílech. 

3) SpusĹĄte Flash CS4

- Vytvoříme si třídu PixelBenderLoader, která bude načítat filtry za běhu a aplikovat je na jakýkoliv DisplayObject = snad jakákoliv vizuální komponenta, MovieClip, Video, Fotka, Vektor apod.

- PixelBenderLoader je moje třída, kterou můžete používat, nicméně inovaci se meze nekladou a určitě si najdete vlastní cestu pro vaše konkrétní využití.

package
{
	import flash.display.*;
	import flash.events.*;
	import flash.filters.*;
	import flash.net.*;
	import flash.events.EventDispatcher;
 
	public class PixelBenderLoader extends EventDispatcher
	{		
		private var loader:URLLoader;
		private var shader:Shader;
		// ShaderFilter muzeme aplikovat pomoci parametru filters DisplayObjectu
		private var filter:ShaderFilter;
 
		public function PixelBenderLoader():void
		{
 
		}
	        // nacteni filtru
		public function loadFilter(filterURL:String):void{
			loader = new URLLoader();
			loader.dataFormat = URLLoaderDataFormat.BINARY;
 
			// odchytime jen udalost nacteni, doporucuju vsak odchytit pripadne errory
			loader.addEventListener(Event.COMPLETE, onComplete);
			loader.load(new URLRequest(filterURL));
		}
 
		// aplikuje filter pomoci transformacni objektu
		public function applyFilter(displayObject:DisplayObject,transformObject:Object){
			applyShaderWithTransformObject(shader,transformObject);
			filter = new ShaderFilter(shader);
			displayObject.filters = [filter];
		}
 
                // vrati filter pro pripadnou aplikaci volnejsim zpusobem
		public function getFilter(transformObject:Object):ShaderFilter{
			applyShaderWithTransformObject(shader,transformObject);
			filter = new ShaderFilter(shader);
			return filter;
		}
 
                // aplikuje transformacni objekt na shader pomoci cyklu
		protected function applyShaderWithTransformObject(shader:Shader,transformObject:Object):void{
			for(var i:String in transformObject){
				shader.data[i].value = [transformObject[i]];
			}
		}
 
		// po naÄŤtenĂ­ filteru
		protected function onComplete(e:Event):void
		{
			shader = new Shader(loader.data);
			dispatchEvent(e);
		}
	}
}

transformObject:Object - hodnoty parametrů, které filter umožňuje měnit
napĹ™. tranformObject = {radius:150};

- Ve Flashi pak pouĹľijeme filter tĂ­mto zpĹŻsobem

NaÄŤtenĂ­ filtru:

var pbl:PixelBenderLoader = new PixelBenderLoader();
pbl.addEventListener(Event.COMPLETE,onComplete);
pbl.loadFilter("twirl.pbj");

Aplikace filtru - v tomto případě budeme měnit radius:
(deformClip je klasickĂ˝ MovieClip v library, obsahuje fotku a dynamickĂ˝ text)

function applyRadius(radius:Number){
	// transformacni objekt, zmenime jen radius
	var transformObject:Object = new Object();
	transformObject.radius = radius;
 
	// zmen dynamicky text
	deformClip.txt.text = radius.toString();
 
	// aplikuj filtr
	pbl.applyFilter(deformClip,transformObject);
}

Změna parametru při pohybu myši:

// zmen radius pri pohybu mysi
function mouseMoveChange(event:MouseEvent):void{
	applyRadius(Math.abs(event.localX));
}

Odchycení události načtení filtru - v tuto chvíli lze začít filter používat:

function onComplete(e:Event):void{
	trace("filter load complete - aplikace");	
	applyRadius(100);
	stage.addEventListener(MouseEvent.MOUSE_MOVE,mouseMoveChange);
}

Demo soubory ke staĹľenĂ­ zde.

Daily Web Conference 2008

November 20th, 2008

I was speaking yesterday at DWC2008, Bratislava - Slovakia, the conference about web technologies in view of managers, marketing people and PR. There has been many top-business people from Slovakia - banks, web leaders.

My session was about the Platform and what it brings to the business they do. I tried to inspire the people - showed AIR demos, 3D possibilities and Pixel Bender filters.

I liked the Gstrinx.sk - nice girls playing electronic violins during networking and reception. Hopefully this wasn’t the last time I saw them
