So basically, you need to read the data from the HDF5 file and render that using VTK. This can be done for your dataset but you will need to write the conversion code. The basic outline would be something like.<div><br class="webkit-block-placeholder"></div><div>Read a timestep of HDF5 data into memory (assuming it will fit)</div><div>Instantiate the appropriate vtk object (would vtkImage be appropriate or vtkStructuredGrid?)</div><div>copy all the data to the vtk object creating scalar and vector attributes as needed.</div><div>save the resulting file to a vtk file (vtkXML....Writer)</div><div><br class="webkit-block-placeholder"></div><div>View data in ParaView (or vtk for that matter).</div><div><br class="webkit-block-placeholder"></div><div>Does this help?</div><div><br><div><div>On Jan 22, 2008, at 11:18 AM, Ogedengbe, Emmanuel wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"> <!-- Converted from text/rtf format --><p dir="LTR"><span lang="en-ca"></span><span lang="en-ca"></span><a name=""><span lang="en-ca"><font size="2" face="Arial">After installation of VTK for use with purely C++ on windows, I have been struggling with how to get started with</font></span></a><span lang="en-ca"></span><span lang="en-ca"><font size="2" face="Arial"> reading my CFD datasets for visualization.</font></span><span lang="en-ca"></span><span lang="en-ca"> <font size="2" face="Arial">I have done some research with HDF5</font></span><span lang="en-ca"></span><span lang="en-ca"><font size="2" face="Arial"> but having problem with</font></span><span lang="en-ca"></span><span lang="en-ca"> <font size="2" face="Arial">having to</font></span><span lang="en-ca"></span><span lang="en-ca"> <font size="2" face="Arial">go into increasing number of third party</font></span><span lang="en-ca"></span><span lang="en-ca"> <font size="2" face="Arial">software</font></span><span lang="en-ca"></span><span lang="en-ca"><font size="2" face="Arial"> and libraries.</font></span><span lang="en-ca"></span><span lang="en-ca"> <font size="2" face="Arial">Recently, I learnt that</font></span><span lang="en-ca"></span><span lang="en"> H5utils</span><span lang="en-ca"></span><span lang="en"> can convert</span><span lang="en-ca"></span><span lang="en"> HDF5 datasets into the formats required by other free visualization software</span><span lang="en-ca"></span><span lang="en"> like VTK.
