Hi, I would like some advice regarding displaying a 2D slice of scalar data on a structured grid in a 3D scene containing polydata using Paraview.<br><br>I have a 2D slice of data from an FE analysis which with I want to view in Paraview. I want to view it on a 2D plane within a 3D 'scene' consisting of 3D polydata. For example I have a vehicle placed in the center of the scene which is imported from a .vtp file I have created. I have analysis results on a plane through the centre of the vehicle. This is scalar data on a 2D structured grid. I want to be able to import the vehicle model in .vtp format and import the analysis results in a standard vtk format and view both. <br><br>The analysis data I have in an vtkimagedata object. One solution is to use the geometry filter and create polydata and write this to a .vtp file. e.g. (assuming the image data is stored in *id);<br><br>vtkImageDataGeometryFilter *idf = vtkImageDataGeometryFilter::New();<br>idf->SetInput(id);<br> <br>vtkXMLPolyDataWriter *writer = vtkXMLPolyDataWriter::New();<br>writer->SetInput(idf->GetOutput());<br>writer->SetFileName(fname.c_str());<br>writer->Write();<br><br>For large data sets the visualisation is slow. What I really want to do is create a plane and texture map the analysis data onto it. I can create a plane with texture coords and export this separately as a .vtp file. I can also export the image data as an image file (png/jpeg etc.). In paraview I can then open the .vtp file containing the plane with texture coords and then apply the texture by reading in the image. <br><br>However, can I do this using a single file? Is there a way to have the texture mapped polydata and texture in one file so that when it is opened you see the texture mapped polydata? Have I gone about this all wrong? Any better ideas as to how I do this?<br><br> Many Thanks,<br><br>JM<br>
