    Hi,
    I’m trying to calculate 3D position of a mouse click position by detected marker’s plane. Is there any easy way to find 3D postion on the marker’s plane? I’ve tried to intersect 2D position with marker’s plane. I can get the ray vector fo the mouse click position by flarCamera3D’s unproject method. I also can get the marker’s 3D position. But I need to find the normal vector of the marker’s plane. So I can build a plane3D with setNormalAndPoint method. Then I can intersect the ray with this plane and the result will be the 3D position of the 2D mouse position. My codes are here:
    var ray:Number3D = flarCamera3D.unproject(mouse.x,mouse.y);
    var p:Plane3D = new Plane3D();
    var normal: Number3D = I DONT KNOW HOW TO FIND??
    p.setNormalAndPoint(normal, markerPosition);
    var intersect:Number3D = p.getIntersectionLineNumbers(flarCamera3D.position, ray);

    I will appreciated if you can help, I didn’t any solutions for days.
