Summary

0011772: vtp and vtk cannot handle more than order 120 million triangles

Description

We think 32 bit integers are used in vtp and vtk files to represent the number of coordinates and polygons. In particular, the offset is suspect. In our case, when the number of points and triangles approaches respectively 60 million and 120 million, paraview cannot render the object. We get the following error:

ERROR: In /Users/partyd/Kitware/ParaView-3.8/src/VTK/IO/vtkXMLUnstructuredDataReader.cxx, line 589
vtkXMLPolyDataReader (0x10a504c00): Cannot read cell offsets from Polys in piece 0 because the "offsets" array is not long enough.

Some versions of paraview are able to read the vtp files on unix boxes. It depends on the build. Here is the header of the vtp file:

[dgd]% head test.vtp
<?xml version="1.0"?>
                                                                                                  <VTKFile type="PolyData" version="0.1" byte_order="LittleEndian">
                                                      <PolyData>
                                                                                                             <Piece NumberOfPoints=" 61342156" NumberOfVerts="0" NumberOfLines="0" NumberOfStrips="0" NumberOfPolys=" 118579532">
                                                             <Points>
                                                                                                               <DataArray type="Float32" NumberOfComponents="3" format="appended" offset="0"/>
                                                                                                         </Points>
                                                                                                              <Polys>
                                                                                                                <DataArray type="Int32" Name="connectivity" format="appended" offset=" 736105876"/>
                                                                                       <DataArray type="Int32" Name="offsets" format="appended" offset=" 2159060264"/>

Steps To Reproduce

Make a vtp file wherein the offset exceeds what can be represented using 32 bit integers. In our case, the actual data files exceed 2.5Gb.

Additional Information

We could use some help. We are keen to render the surfaces. Thanks, Doug.
