hello,

i'm working with mogre and i have a problem.

i'm trying to use PlaneBoundedVolumeListSceneQuery as seen in tutorial 4 for make a Rectangular Selection

with this code



            Camera cam = GetCamera(); //is not null



            Ray topLeft = cam.GetCameraToViewportRay(left, top);

            Ray topRight = cam.GetCameraToViewportRay(right, top);

            Ray bottomLeft = cam.GetCameraToViewportRay(left, bottom);

            Ray bottomRight = cam.GetCameraToViewportRay(right, bottom);



            PlaneBoundedVolume vol = new PlaneBoundedVolume();

            vol.planes.Add(new Plane(topLeft.GetPoint(3), topRight.GetPoint(3), bottomRight.GetPoint(3)));      // front plane

            vol.planes.Add(new Plane(topLeft.Origin, topLeft.GetPoint(100), topRight.GetPoint(100)));           // top plane

            vol.planes.Add(new Plane(topLeft.Origin, bottomLeft.GetPoint(100), topLeft.GetPoint(100)));         // left plane

            vol.planes.Add(new Plane(bottomLeft.Origin, bottomRight.GetPoint(100), bottomLeft.GetPoint(100)));  // bottom plane

            vol.planes.Add(new Plane(topRight.Origin, topRight.GetPoint(100), bottomRight.GetPoint(100)));      // right plane



            PlaneBoundedVolumeList volList = new PlaneBoundedVolumeList();

            volList.Add(vol);



            _selectionRectangleSceneQuery.SetVolumes(volList);

            SceneQueryResult result = _selectionRectangleSceneQuery.Execute();



            if (result.movables == null) return;



            foreach (MovableObject res in result.movables)

            {

                       //HERE DON'T FIND THE ROBOTS THAT RAY QUERY FIND

             }

i don't understand why ray query catch the robot and volume query don't

this is a shot of the selected rectangle
