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
