I have a script that uses a lot of complicated .draw calls with matrix transformation (scale and shift), displaying different parts of a big image (thousands by thousands px) in a kind of navigatior window.
Currently it's done in "old" AS3 for FP10. Is there a way to speed these calls up using GPU and stage3D in the new player FP11?
Can GPU help with that kind of image manupulation?
Good news, thank you!
Can anyone tell me what could be a Stage3D equivalent of this:
var img:BitmapData = .......
var rgn:Rectangle = ........
var scl:Number = ....
var matrix:Matrix = new flash.geom.Matrix();
rgn.x *= scl;
rgn.y *= scl;
rgn.width *= scl;
rgn.height *= scl;
matrix.tx = -rgn.left;
matrix.ty = -rgn.top;
var mapBD:BitmapData = new BitmapData(rgn.width,rgn.height,false,0x000000);
var mapLayer:Bitmap = new Bitmap(mapBD);
Here is an intro to AGAL and shaders:
