Marker Coordinates

Oct 4, 2010 at 4:50 PM

Hello everybody,

is it possible to know the position of the marker when it is tracked?

I noticed you can read a WorldTransformation matrix from the markerNode (and from other nodes too), but can't understand if it could be useful or not for my aim.

I did some tries involving matricial calculations but couldn't get to a solution.

Any help, please?

MarkerNode.WorldTransformation gives your exactly what you need for the position of the marker relative to your camera (it's relative position, not absolute).

Ok, so i'll need to multiply markernode.WorldTransformation and scene.CameraNode.WorldTransformation?

This way i'll get a 4x4 matrix where only the first 2 rows and columns are of my interest, right?
