I use Math.sin and cos for flying of butterfly. First, double wind should be used by sin wave. Second, parent butterfly, too. And this sample use RefrectionView which is new base class of Papervision3D 2.0(GreateWhite).
I discovered PV3D available for depth of field blur by useowncontainer property. The prpperty useOwnContainer can apply filter, alpha, and blendMode on 3D object. And it’s possible to check 3D scene position with new property named screenX, screenY, screenZ.
