With the code below, i´m tryign to read a .img (a format that have inside a stack of 40 .raw images of 159x147) and to visualize it like a 3D data set. All of this in JAVA. The error vtk shows is: "ERROR: In C:\martink\vtk42\VTK\Graphics\vtkPolyDataNormals.cxx, line 88
vtkPolyDataNormals (0x0C702AE8): No data to generate normals for!" And i don´t know where is the problem, if the .img is bad for this or i forget doing somethig.
Thank you in advance and sorry for my English.
vtkImageReader reader=new vtkImageReader();
reader.SetDataScalarTypeToUnsignedChar();
reader.SetDataByteOrderToBigEndian();
reader.SetNumberOfScalarComponents(1);
reader.SetFileDimensionality(3);
reader.SetDataExtent(0,157,0,146,0,39);
reader.SetFileName("C:/Documents and Settings/Pc2/Escritorio/VTKs/prueba6.img");
vtkContourFilter skinExtractor = new vtkContourFilter();
skinExtractor.SetInput(reader.GetOutput());
skinExtractor.SetValue(0, 255);
vtkPolyDataNormals skinNormals = new vtkPolyDataNormals();
skinNormals.SetInput(skinExtractor.GetOutput());
skinNormals.SetFeatureAngle(60.0);
