finally!! I got it! eureka :P
this is how I solved the problem, just in case anyone has gotten this
problem too.
the firs step is to load the avatar, to load the avatar I have my
scripts to get all the clothes, hair style, skin color etc, from the
DB,
from that DB data, I build an away3d model (till here, everything is
just like I had it before the techinque).
now I apply the techinque:
0.- create an array, and create a Bitmap object, also make sure to set
your view.session to a new BitmapSession(1);
1.-I add the avatar to a view3d and use a Rectangle clipping so It
only renders the avatar area, and not the whole scenario.
2.- I create my avatar3d model, and call its own away3d method
playAnimation("animation_name");
3.- instead of using the typicall way to render: adding a ENTER_FRAME
event and inside calling the view.render();
I use a for to render all of the frames, but there is a problem,
animation does not advance, why? cause internally it uses an enter
frame event, so the solution is calling
myAvatar.gotoAndPlay(frameNumber) and just after that, I call the
view.render() method.
the lenght of the for is the number of frames in the animation you
want to render.
4.- inside the for, and just after calling view.render(), you create a
new BitmapData, and use the method view.getBitmapData().clone() to
clone the data gotten from the render. assign this to the new created
bitmapData, and then, push this bitmapData to the array created on
step 0.
at this point you can delete your 3d instance already.
5.- after the for, all renders from every animation's frames, should
've been saved on the array.
6.- add an ENTER_FRAME listener into your Bitmap created on step 0.
and create a variable wich holds the current animating frame.
inside on the event, set your bitmap.bitmapData to the bitmap data
array, on the currentframe possition and then add ++ to your
currentframe. and make sure to reset current frame to 0 when
currentframe> array length.
I repeat those steps for every diferent avatar I want to render.
and that's it, I already tested with 100 avatars, eachone with 300
polys, and it runs just like butter.
here is a sample source code of the algorithm:
hope it helps.
this is for testing 100 avatars:
var data:Array = renderAnimation("walk");
for (var i:int = 0; i < 100; i++)
{
var obj:MovieClip = new MovieClip();
var renderContainer:Bitmap = new Bitmap();
obj.renderContainer = renderContainer;
obj.current3dFrame = 1;
renderContainer.x = (-200)+(i * 10);
obj.addEventListener(Event.ENTER_FRAME, update);
this.addChild(renderContainer);
}
function update(e:Event):void
{
if (e.currentTarget.current3dFrame > 59)
{ e.currentTarget.current3dFrame = 1; }
e.currentTarget.renderContainer.bitmapData =
data[e.currentTarget.current3dFrame];
e.currentTarget.current3dFrame++;
}
function renderAnimation(animation:String):Array{
var render:Array = new Array();
avatar.playAnimation(animation);
for (var i:int = 0; i < 60; i++) {
avatar.getBodyPart(BodyPart.HAIR).gotoAndPlay(i);
avatar.getBodyPart(BodyPart.HEAD).gotoAndPlay(i);
avatar.getBodyPart(BodyPart.PANTS).gotoAndPlay(i);
avatar.getBodyPart(BodyPart.SHIRT).gotoAndPlay(i);
avatar.getBodyPart(BodyPart.SHOES).gotoAndPlay(i);
view.render();
render.push(view.getBitmapData().clone());
}
return render;
}
