[Papervision3D] flartoolit and Matrix3D

[endrone endrone]

Thanks for the feedback,

@Ross
I tried the lookAt function, but this doesn't seem to work. The plane even
misteriously dissapears :) But it is so that both camera and 3d objects
don't rotate so x, y, z, rotationX,... are all still 0. It justs alterres
the transform property of the 3d objects container (called
baseNode:DisplayObject3D).

@Carlos
I want to try to manipulate the matrix, but I don't know how. The first
thing that I would need to know is how to get te rotations from the original
Matrix3D so I can set them on the transform matrix of the plane. The
Matrix3D.matrix2euler() only seems to be able to set the rotations, not to
read them.
