[vtkusers] pb vtkMarchingCubes: not all the triangles are displayed

[Thomas Deschamps]

Hi vtkUsers,

I have a problem since I downloaded the latest cvs snapshot of the VTK 
directory: When I am using vtkMarchingCubes, not all the triangles 
extracted are represented. For example, a shpere will be partially 
represented (only a connected part of it in fact). The code I use is 
very standard, here it is:


        vtkMarchingCubes * marchingCubes = vtkMarchingCubes::New();
        marchingCubes -> SetValue(0,this -> isoValue);
        marchingCubes -> SetInput(importer -> GetOutput());
        marchingCubes -> SetOutput(polyData);
       
        vtkPolyDataMapper * mapper3D = vtkPolyDataMapper::New();
        mapper3D -> ScalarVisibilityOff();
        mapper3D -> SetInput(polyData);
        mapper = mapper3D;
       
        vtkActor * actor3D = vtkActor::New();
        actor3D -> SetMapper(mapper3D);
        etc...


In fact it looks like there is a limit on the number of triangles 
extracted. Does it mean something to someone?
Thank you.
