Some of you asked me, for some reason, to update an old array-sort-example i´ve rewritten for flash6 in due time - the heapsort. I think it´s not necessary nowadays because flashs built-in array sort-methods are quick and easy to use, but for all those who asked for - here´s a little as3 heapsort class ( download fla and class ).

package fr.utils {
public class heapsort {

var n:int;
var w:int;
var a:Array;

public function heapsort( arr:Array ) {
a = arr;
n = arr.length;
initheap();
}

private function initheap() {
buildheap();
while( n>1 ) {
n–;
exchange(0,n);
downheap(0);
}
}

private function buildheap() {
for (var v:int=n/2-1; v>=0; v–) {
downheap (v);
}
}
private function exchange( i:int, j:int ) {
t=a[i];
a[i]=a[j];
a[j]=t;
}

private function downheap( v:int ) {
w = 2*v + 1;
while ( w
if ( w+1
if ( a[w+1]>a[w] ) w++;
}
if (a[v]>=a[w]) return;
exchange(v, w);
v=w;
w=2*v+1;
}
}
}
}

Last days the company i work for ( anyMOTION Graphics ) released the first betaversion of my 3D room-viewer application. i scripted this api within´ three days, so let´s say it´s a ruff sneak preview of what it´s going to be when it´s finalized later on. So here you have an eye up on it.

- Use the arrow buttons ( down right and left ) to rotate horinzontal

- Use the magnifier buttons ( upper right corner ) to zoom in and out

- Press and hold mouse button down, then move mouse to rotate vertically

last days i played around with papervision3d once again…

my thought was to script some kind of fluid forms in actionscript3 and then use ´em as texture for papervision3D-objects. the result is this little applet i called pv3d waveforms. And for sure you can download the sources…

2 weeks full of pure relaxation are over now. my great efforts there were reading a few good books, spending time at the beach or pool, enjoying the sun and just doing nothing. So i´m recovered now and looking forward to post some as3-snippets i had in my mind in the past 2 weeks…
