Clipping plane related rendering problem
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Clipping plane calculation seems to have problems when the data bounds include large numbers. Bug report from Renato below. To reproduce, load the attached dataset, zoom until close and rotate.
A friend brought me a question about a rendering problem in ParaView. He created a very simple dataset in VTK legacy format (available in http://www.nacad.ufrj.br/~rnelias/paraview/Celula_reservatorio.vtk) and loaded the data in PV (versions 2.6.2 and 3.1.0) without any problem but, when he tries to move and rotate the geometry it turns completely distorted and messed (as can be seen here http://www.nacad.ufrj.br/~rnelias/paraview/Celula_paraview2.JPG and here http://www.nacad.ufrj.br/~rnelias/paraview/Celula_paraview.JPG). My first thought was that it could be a driver problem so I tried to reproduced the same problem in my computer which showed me the same problematic geometry (only when I move and rotate the model). If you look into the data supplied you can see that the point coordinates are a bit large, here is another suspicious... Maybe VTK or PV is getting a confused about so large point coordinates. Does anyone have any idea about what is happening?
Thanks for any help
