Dear Paraview List, I'm trying to read some HDF files, which contain dense voxel data. In my calculations, I write out the HDF and wrapper XDMF data to store timestep and other metadata.
This all works fine, until I want to have 2 different voxel sizes at 2 different timesteps (different number of voxels in each dimension). When loading up the data as a series of time-steps, everything works until I reach the first set of data from the new size. When loading the data, the values in the voxels seem to become invalid, and the bounding box around the data starts moving in the direction of (1,1,1). I can load each timestep individually correctly, it is just when I try to load the entire timeseries that it fails. Does anyone know a solution for this? I have raw voxel grids in the program that generates the data, so I need to wrap them in something to provide a timestep. I'd rather avoid having to interface with VTK, as the code I am working on does not have a VTK dependency - I'm just post-processing with paraview. I'm opening the series via: File->Open, then select the tree item data-..xmdf each file is written as: data-1.hdf.xmdf data-2.hdf.xmdf .... The XMDF files contain something like this Before problem timestep: ========== <?xml version="1.0" ?> <!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []> <Xdmf xmlns:xi="http://www.w3.org/2003/XInclude"; Version="2.2"> <Domain> <Grid Name="Data" GridType="Uniform"> <Topology TopologyType="3DCORECTMesh" Dimensions="39 39 39"/> <Geometry GeometryType="ORIGIN_DXDYDZ"> <DataItem Name="Origin" Dimensions="3" NumberType="Float" Precision="4" Format="XML">-1.26667 -1.26667 -1.26667</DataItem> <DataItem Name="Spacing" Dimensions="3" NumberType="Float" Precision="4" Format="XML">0.0666667 0.0666667 0.0666667</DataItem> </Geometry> <Attribute Name="second 0" AttributeType="Scalar" Center="Node"> <DataItem Format="HDF" NumberType="Float" Precision="4" Dimensions="39 39 39">data-59.hdf:/voxels</DataItem></Attribute> </Grid> </Domain> </Xdmf> ========== After problem timestep: ========== <?xml version="1.0" ?> <!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []> <Xdmf xmlns:xi="http://www.w3.org/2003/XInclude"; Version="2.2"> <Domain> <Grid Name="Data" GridType="Uniform"> <Topology TopologyType="3DCORECTMesh" Dimensions="31 31 31"/> <Geometry GeometryType="ORIGIN_DXDYDZ"> <DataItem Name="Origin" Dimensions="3" NumberType="Float" Precision="4" Format="XML">-1 -1 -1</DataItem> <DataItem Name="Spacing" Dimensions="3" NumberType="Float" Precision="4" Format="XML">0.0666667 0.0666667 0.0666667</DataItem> </Geometry> <Attribute Name="second 0" AttributeType="Scalar" Center="Node"> <DataItem Format="HDF" NumberType="Float" Precision="4" Dimensions="31 31 31">data-60.hdf:/voxels</DataItem></Attribute> </Grid> </Domain> </Xdmf> ========== Thanks! _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview
