The class that manages the camera position is the VTK class vtkCamera. Although internally it transform coordinate systems to place objects, all parameters for vtkCamera (and all other VTK classes) are defined in world space.
If you want to change the coordinate systems of one of the objects in ParaView, you can use the Transform filter. There are also some transformation controls in the Display panel of each object. -Ken On 9/24/09 8:56 PM, "Arsham Mesbah" <[email protected]> wrote: Hi Does anyone know how different coordination systems is being handled in ParaView and How paraview keeps track of the the transformation from one to another one! Here is my train of thoughts, well in any 3D Visualization system we have a "Point of View" which I think in ParaView is handled with a Class (ParaView uses the term Camera I think) which I assume it is in a different coordinate system than Our actual scene! (I would actually like to know name of and the location of the camera class in ParaView Source if you know where it is please do let me know) Further more, we might have more than an object which we are visualizing (reading off of vtk file) and they might be in different coordinate systems how does ParaView handle this? which class is used to handle this kind of differences and how ParaView keeps the track of these transforms? Any specific Proxy or Super class is used here to handle this? I would appreciate any help or comment! **** Kenneth Moreland *** Sandia National Laboratories *********** *** *** *** email: [email protected] ** *** ** phone: (505) 844-8919 *** web: http://www.cs.unm.edu/~kmorel
